Abstract

Morphological and phylogenetic analyses of large ribosomal subunit (28S rDNA) and internal transcribed spacer (ITS rDNA) of Terfezia samples collected from several bioclimatic zones in Algeria and Spain revealed the presence of six distinct Terfezia species: T. arenaria, T. boudieri, T. claveryi; T. eliocrocae (reported here for the first time from North Africa), T. olbiensis, and a new species, Terfezia crassiverrucosa sp. nov., proposed and described here, characterized by its phylogenetic position and unique combination of morphological characters. A discussion on the unresolved problems in the taxonomy of the spiny-spored Terfezia species is conducted after the present results.

Keywords: desert truffles, Pezizaceae, phylogeny, taxonomy, Fungi

Terfezia crassiverrucosa Zitouni-Haouar, G. Moreno, Manjón, Fortas, & Carlavilla, sp. nov.  

  Diagnosis:— Ascomata hypogeous, subglobose, substipitate with short basal attachment, <8 cm broad (Fig. 2a). Peridium smooth, light to dark brownish, 100–200 µm thick with emergent hyphae 6–10 µm broad at septa, pseudoparenchymatous, composed of subglobose, polygonal to irregularly oblong cells (9–) 12.5–38 × 15–60(–62) µm, with cell walls 1–2 µm thick. Gleba solid, fleshy, light pink to pale yellow with subglobose to elongate light pink to pale gray pockets of fertile tissue, separated by light yellow to pale orangish yellow sterile veins (Fig. 2b). Asci (4–6)–8– spored, hyaline, often ellipsoid to ovoid or at times subglobose, 51–60 × 60–81 µm, nonstalked (Fig. 2 c & d). Ascospores globose, first hyaline, turning light yellowish to bright orange with age, measuring (16–) 17–21 (–24) µm in diameter including ornamentation, consisting in more or less broad flat truncate to round-tipped warts (0.5–) 1–1.5 × 2–4.5 (– 6) µm, and relatively elongated rounded elements measuring 1–1.5 × 1.5–3 µm. The prominent, crowded ornamentation hides a fine reticulum on the spore surface formed between the warts (Fig. 2 c–h).

Etymology:— The epithet (Latin crassiverrucosa) refers to the large warts covering the spore surface of this species. 

Habitat:— Algerian arid area. In high steppe plains south of Constantine (Chrea, Tebessa), associated with Helianthemum sp.

[Botany • 2017] Aloe belitsakensis • A New Species (Asphodelaceae) from north-western Madagascar ---ScRaBBlE

 Aloe belitsakensis

in Rakotoarisoa & Grace, 2017

@TeamKMCC ||  DOI: 10.11646/phytotaxa.328.3.6 

Madagascar is a major centre of diversity for the leaf-succulent genus Aloe Linnaeus (1753: 319) accounting for roughly a third of Aloe species (Carter et al. 2011). Approximately 128 species and 161 taxa are known from the region and all are restricted to Madagascar (Rakotoarisoa et al. 2014) and/or the nearby Mascarene archipelago. New taxa are described from these islands at a rate that rivals the ongoing discovery of aloes elsewhere in their natural range, on the African continent or Arabian Peninsula (Crouch et al. 2013). Extinction risks are alarmingly high among species of Aloe in this region. Conservatively, 39% of species are known to be threatened, and this figure is likely to be significantly higher (Rakotoarisoa et al. 2014), since several species have not been observed or collected for many decades. The Kew Madagascar Conservation Centre (KMCC) aims to record and collect the rare and threatened flora of Madagascar to ensure its conservation, and the genus Aloe is a priority for the dryland programme.

[Botany • 2018] Rediscovery of the Presumed-Extinct Dracaena umbraculifera || A Botanical Mystery Solved by Phylogenetic Analysis of Botanical Garden Collections ---ScRaBBlE

Abstract
Extinction is the complete loss of a species, but the accuracy of that status depends on the overall information about the species. Dracaena umbraculifera was described in 1797 from a cultivated plant attributed to Mauritius, but repeated surveys failed to relocate it and it was categorized as Extinct on the IUCN Red List. However, several individuals labelled as D. umbraculifera grow in botanical gardens, suggesting that the species’ IUCN status may be inaccurate. The goal of this study was to understand (1) where D. umbraculifera originated, (2) which species are its close relatives, (3) whether it is extinct, and (4) the identity of the botanical garden accessions and whether they have conservation value. We sequenced a cpDNA region of Dracaena from Mauritius, botanical garden accessions labelled as D. umbraculifera, and individuals confirmed to be D. umbraculifera based on morphology, one of which is a living plant in a private garden. We included GenBank accessions of Dracaena from Madagascar and other locations and reconstructed the phylogeny using Bayesian and parsimony approaches. Phylogenies indicated that D. umbraculifera is more closely related to Dracaena reflexa from Madagascar than to Mauritian Dracaena. As anecdotal information indicated that the living D. umbraculifera originated from Madagascar, we conducted field expeditions there and located five wild populations; the species’ IUCN status should therefore be Critically Endangered because < 50 wild individuals remain. Although the identity of many botanical garden samples remains unresolved, this study highlights the importance of living collections for facilitating new discoveries and the importance of documenting and conserving the flora of Madagascar.

[Botany • 2017] Dioscorea irodensis • A New Species of Critically Endangered Edible Yam (Dioscoreaceae) Endemic to northern Madagascar and Its Conservation ---ScRaBBlE

 Dioscorea irodensis  Wilkin, Rajaonah & Randriamb.

 DOI: 10.1007/s12225-017-9677-6 

Summary

Morphological character data are used to show that a distinct morphotype of Dioscorea L. from the Irodo valley (East of Sadjoavato) in Antsiranana Province of Madagascar is an undescribed species, differing in its leaf arrangement, pubescence form and male inflorescence structure from all other taxa. It is described as Dioscorea irodensis Wilkin, Rajaonah & Randriamb., illustrated and a distribution map and ecological information provided. It is known from three sites, but is likely to have been eradicated from one of them. The population that has been studied in the field contains a very low number of adult plants. Tubers have been extracted for use as food at a level that appears to be unsustainable. Thus its provisional IUCN conservation status assessment is that it is critically endangered (CR). Its vernacular name in Irodo is Bemandry.

Key Words: conservation, critically endangered, distribution, edible, ex situ, in situ, Madagascar, morphology, new species, yam

Dioscorea irodensis Wilkin, Rajaonah & Randriamb., sp. nov. 

Type: Madagascar, Antsiranana: Diana, Antsiranana II, Anivorano, Irodo, ala fady S of village towards Irodo river estuary, 12°39'6.3"S 49°31'38.2"E, ♀ fr. 8 Feb. 2015, P. Wilkin, J. A. Kennerley, F. Rakotonasolo, M. Hamido & M. Tsaratiana 1675 (holotype TAN!; isotype K!).

Recognition. Tuber horizontal in soil with a curved apex (derived from digging up two plants and inferring a similar position in others from the shape of extraction holes and the Malagasy vernacular name). Leaves in clusters of up to 7 on short herbaceous branches, clustered particularly towards bases of main vegetative stems (Fig. 1A, 2B), blades thin in texture, densely pubescent below and when immature but coarse and never forming a tomentum as in Dioscorea ovinala. Plants at the locality near Irodo represented by Wilkin et al. 1674 and 1675 often have white spotting on their leaf blades which has the appearance of pathogenic infection (see Fig. 2A). Male inflorescences (Fig. 1 E, F) with irregularly spaced, spirally arranged dense cymules of 2 – 8 pedicellate flowers or rarely solitary, vs flowers (sub)sessile, or rarely with a pedicel to 0.5 mm long and solitary or in groups of 2 – 4 (D. ovinala). Fruit not inflated and fleshy during development but thin-lobed and capsular throughout, single layered at dehiscence. Restricted to a small area East of Sadjoavato in Antsiranana Province.

Distribution and habitat. Endemic to the Irodo river Valley and Sahafary forest in Antsiranana Province (Map 1) at altitudes from 30 – 230 m. It is possible that the three collections from South of the village of Irodo represent two subpopulations on either side of the river as opposed to two distinct populations (the term population is used here in an ecological sense, except in the Conservation Status section), but the specimen from Sahafary forest is spatially isolated. At Irodo, it is found in semi-deciduous forest with a canopy to 10 m and a clear shrub layer, the principal canopy trees being Colvillea and Tamarindus, with Pachypodium in the shrub layer. Soil a brown sandy loam, possibly alluvial, or red sand over limestone bedrock. The Sahafary Forest specimen states that it was from scrub forest on red sand.

Etymology. Named for the village of Irodo and the Irodo River valley where this species is found.

Vernacular name. Bemandry in the village of Irodo. This name appears to be applied particularly to species with horizontal tubers, for example the element of Dioscorea soso Jum. & H. Perrier sensu lato with the same tuber habit.

Uses. Tuber edible cooked. Rather watery following cooking and thus not fully satisfying the appetite. Dioscorea maciba, known as batatala in Irodo, is the more sought after species of the two that are found in the Irodo valley and surrounding areas. Not believed to be sold in markets but consumed usually in March/April.

[Botany • 2017] Satyrium liltvedianum • A Newly Discovered Orchid Species from the Kogelberg Mountains of the Cape Floristic Region, South Africa ---ScRaBBlE

Satyrium liltvedianum Van der Niet

DOI: 10.1016/j.sajb.2017.03.018 

 Highlights

• A new orchid species was discovered in the well-botanised Kogelberg Mountains.

• The new species was not present among historical museum collections.

• The new species resembles other Satyrium species, but is phylogenetically distinct.

• The compound β-Linalool dominates the floral scent, indicative of moth pollination.

Abstract

Individuals of plant populations with traits which are inconsistent with any existing species description may represent intraspecific variants, products of hybridisation, or a novel species. To distinguish among these possibilities for a population of unusual Satyrium individuals from the Kogelberg Mountains in the Cape Floristic Region (CFR), morphological traits and floral scent were documented, and phylogenetic analyses implemented. Plants from the Kogelberg population were characterised by long-spurred white flowers and a bifid rostellum. Floral scent was dominated by the common floral monoterpene volatile β-linalool. Although these traits characterise several southern African members of the genus, DNA sequences from the nuclear and plastid genomes of an accession from the Kogelberg population were highly distinct from other Satyrium species. The Kogelberg accession occupied an isolated phylogenetic position within the ‘Satyrium clade’ and was not sister to any other species with similar traits. There was weak support for membership of a clade of species with which plants from the Kogelberg population share the possession of lateral sepals that project at a perpendicular angle to the median sepal, and cover the side of the labellum, and which also produce β-linalool as dominant scent compound. Given the congruence of phylogenetic relationships inferred from plastid and nuclear DNA sequences respectively, a hybrid status of the Kogelberg population was rejected. Based on these results, the new species, Satyrium liltvedianum, which is uniquely characterised by the size, shape and orientation of sepals and lateral petals, is described in this study. Other Satyrium species with similar floral traits are pollinated by crepuscular moths, which therefore can also be inferred for the new species. A dichotomous key to the white-flowered, long-spurred Satyrium species of South Africa is provided. The restricted distribution range, a typical phenomenon for many CFR plant species, in combination with the isolated phylogenetic position, suggests that S. liltvedianum represents a palaeoendemic species.

DOI: 10.1016/j.sajb.2017.03.018

Satyrium liltvedianum Van der Niet sp. nov. is morphologically similar to S. candidum, but differs from this species by having lateral sepals that overlap with the outside surface of the labellum and project at a ninety-degree angle from the median sepal instead of projecting from the same plane, and lateral sepals and petals that are approximately equal in size instead of smaller lateral petals than lateral sepals, and a median sepal that is narrower and longer than the lateral sepals instead of more or less similarly-sized.

TYPE.— Western Cape Province, 3418 (Somerset West): Steenbras Catchment area near Rockview Dam, Kogelberg Mountains (–BB), 18 Nov 2009, W.R. Liltved 120 (NBG, holo.).

Distribution: S. liltvedianum is known from a single population in the Steenbras Catchment area of the Kogelberg Mountains.

Etymology: This species is named in honour of William Rune Liltved (1960–) who, over the past two decades, has made an invaluable contribution to recording the orchids of the Cape Floristic Region. This work culminated in publication of the book, The Cape Orchids ( Liltved and Johnson, 2012).

Conservation status: Similar to several other orchids from the CFR, S. liltvedianum is known only from a single localised population of about 50 individuals (Linder and Kurzweil, 1999). The species is therefore considered highly vulnerable.

Conclusion: 

There are many reasons why efforts to discover and describe species should be ongoing. Only recognised taxa can be adequately conserved; the success of scientific research often depends on sound taxonomic classification; beneficial properties of species can only be communicated if a species has a formal name; and recently Dijkstra (2016) argued that because naming species is inherent to human nature, continued exploration for the vast majority of species that are still unknown will improve our consciousness of the natural world. Much of Earth's biotic diversity is currently highly threatened and many species are on the brink of extinction, or have recently gone extinct (Wake and Vredenburg, 2008; Barnosky et al., 2011;  McCallum, 2015), which provides a great sense of urgency to taxonomic enterprise. Several studies, including this study, have shown that new species are regularly still discovered in the field (e.g. Linder and Hitchcock, 2006 ;  Steiner, 2011). Therefore, taxonomy cannot solely rely on historical herbarium or museum collections, even from within relatively well-botanised areas such as the Kogelberg Biosphere Reserve of the CFR, only 70 km from the city of Cape Town.

[Botany • 2017] Taxonomic Revision of Rhodalsine (Caryophyllaceae): A Plant that Linnaeus Forgot ---ScRaBBlE

Rhodalsine geniculata  (Poir.) F. N. Williams

in Kool & Thulin. 2017.

DOI: 10.3372/wi.47.47313 

Abstract 

The mainly Mediterranean genus Rhodalsine (Caryophyllaceae) is revised and a single species, R. geniculata, is recognized, distributed from the Canary Islands in the west to Somalia in the east. The history of the taxon, which was known already during the 17th century but entirely overlooked by Linnaeus, is outlined. Variation and taxonomy are discussed and illustrations and a distribution map are provided. Many names are placed in synonymy and most of the names are typified, including six lectotypes designated here.

Keywords: Caryophyllaceae, Mediterranean region, Minuartia, nomenclature, Rhodalsine, Sperguleae, taxonomy, typification

Description — Herbs perennial or sometimes annual, with indumentum of glandular hairs. Leaves opposite, without stipules, but leaves of each pair with shortly connate bases. Flowers in lax cymes. Sepals 5, connate at base into a short hypanthium. Petals 5, pink or white, inserted at apex of hypanthium, shortly clawed at base. Stamens 10, in 2 whorls, those of outer whorl inserted at base of petals, those of inner whorl antisepalous, inserted on a low, ring-shaped rim surrounding base of ovary; pollen trizonocolpate. Ovary shortly stipitate, subglobose, thin-walled; styles 3, filiform. Capsule opening by 3 valves. Seeds many, orbicular-reniform, wingless; radicle of embryo accumbent. Chromosome base number x = 9.

Distribution — A genus of a single variable species distributed in the Canary Islands, around the Mediterranean and in the Horn of Africa region.

— Holotype: without locality, [Poiret] s.n. (P-LA! [P00287174]).

Distribution and ecology — Rhodalsine geniculata is known from Portugal, Spain (including the Canary Islands, Melilla and the Balearic Islands), Gibraltar, Italy (including Sardinia, Sicily, Pantellaria and Linosa), Malta, Greece, Cyprus, Morocco, Algeria, Tunisia, Libya, Egypt and Somalia (Fig. 3). It occurs in sandy, stony or rocky places from near sea level up to 2050 m. In most of its range it is found at elevations below 600–700 m and it is often confined to habitats on or close to sea shores. However, in Morocco the species is also found at elevations up to about 1500 m in the Atlas Mountains, whereas in Somalia the known altitudinal range is 1350–2050 m.

[Botany • 2017] Begonia nosymangabensis & B. pteridoides • Two New Species of Begonia sect. Erminea (Begoniaceae) from Nosy Mangabe in Madagascar ---ScRaBBlE

Begonia pteridoides & Begonia nosymangabensis

DOI:  10.15553/c2017v722a3 

Abstract

Begonia nosymangabensis Scherber. & Duruiss. and Begonia pteridoides Scherber. & Duruiss. are described and illustrated. Both new species belong to Begonia sect. Erminea A. DC. Begonia nosymangabensis is compared to Begonia keraudreniae Bosser, from which it differs in having larger and more deeply incised leaves which lack adaxial hairs. Begonia pteridoides is related to Begonia bogneri Ziesenh. but differs by its very divided leaves. Both new species are micro-endemics, restricted to Nosy Mangabe island in northeast Madagascar and are assessed as “Vulnerable” according to the IUCN Red List Categories and Criteria.

Résumé: Begonia nosymangabensis Scherber. & Duruiss. et Begonia pteridoides Scherber. & Duruiss. sont décrits et illustrés. Les deux nouvelles espèces appartiennent au genre Begonia sect. Erminea A. DC. Begonia nosymangabensis se rapproche de Begonia keraudreniae Bosser, dont il diffère par ses feuilles plus grandes et plus profondément incisées et l'absence de poils à la face adaxiale. Begonia pteridoides est apparenté à Begonia bogneri Ziesenh., mais en diffère par ses feuilles très divisées. Les deux nouvelles espèces sont des micro-endémiques, restreintes à l'île de Nosy Mangabe au nord-est de Madagascar et sont considérées comme «Vulnérables» selon les Catégories et Critères de la Liste Rouge de l'UICN.
