Abstract

Vietnamocasia, a new monotypic aroid genus in the Alocasia-Colocasia clade, is described with the type species, Vietnamocasia dauae. Vietnamocasia is distinguished by possessing free individual staminate flowers, lacking expanded synconnectives, and having nodding inflorescences. Vegetatively Vietnamocasia is reminiscent of species of the distantly closely related Alocasia Cuprea Group, although Vietnamocasia is so far only known from the type locality in Central Vietnam, over 1200 km NE from the nearest representative of the Alocasia Cuprea Group. The phylogenetic analyses of Vietnamocasia dauae together with representative taxa from all genera of the Alocasia-Colocasia clade recovered Vietnamocasia as a strongly supported clade sister to Alocasia, together nested in a clade to which Leucocasia is a sister taxon. Vietnamocasia dauae is illustrated from living plants and with a line drawing. A key to all genera of Alocasia-Colocasia clade is included.

Vietnamocasia N.S.Lý, S.Y.Wong & P.C.Boyce, gen. nov.

Type: Vietnamocasia dauae N.S.Lý, S. Y. Wong, T.Haevermans & D.V.Nguyen, sp. nov.

Etymology:— Vietnamocasia is compounded from the Greek classical name kolokasia, itself from an old Middle Eastern name qolqas (Nicolson 1987) and the root of Alocasia and Leucocasia (and the more distantly related Colocasia) + Vietnam.

Distribution:— Vietnamocasia is so far known only from the type locality and its vicinity.

Ecology:— At Mount Dầu Vietnamocasia dauae grows in moist shady understory of hillsides in secondary broadleaved forest dominated by dipterocarps at 150–490 m elevation. At the other known locality, Cà Đam, it occurs in primary evergreen broad-leaf forest at about 790 m elevation.

Vietnamocasia dauae N. S. Lý, T. Haevermans, Y. S. Wong & D. V. Nguyen, sp. nov.

Etymology:— The specific epithet is for Mount Dầu, the type locality, treated as feminine.

[Botany • 2017] Arisaema brinchangense Y.W. Low, Scherberich & Gusman (Araceae), A New Threatened Species Endemic to the Cameron Highlands (Peninsular Malaysia) ---ScRaBBlE

Arisaema brinchangense Y.W. Low, Scherberich & Gusman

DOI: 10.15553/c2016v711a10

Abstract

Arisaema brinchangense Y.W. Low, Scherberich & Gusman (Araceae) is described as new and illustrated. The new species is similar to Arisaema anomalum Hemsl. but differs by the morphology of its spathe. It is placed under Arisaema sect. Anomalum Gusman & L. Gusman based on morphological and growth characters, the latter observed in the field and unique to that section. Arisaema brinchangense is endemic to the Cameron Highlands, Pahang, Peninsular Malaysia, and is assessed as “Critically Endangered” following IUCN Red List Categories and Criteria due to habitat loss.

Keywords: ARACEAE, Arisaema, Peninsular Malaysia, Cameron Highlands, Taxonomy, New species

Etymology. – The species epithet refers to Mount Brinchang (2,031 m), where the type specimen was collected.

Distribution and Habitat.– Arisaema brinchangense is so far known only from around the summit of Mount Brinchang, Cameron highlands where it grows in the montane forest c. 2000 m on moist forest floor covered with thick organic litter under deep to semi-shaded condition.

[Botany • 2018] Cryptocoryne joshanii (Araceae) • A New Species Serendipitously Discovered in Sulu archipelago, Philippines ---ScRaBBlE

Cryptocoryne joshanii Naive & Villanueva

in Naive & Villanueva, 2018.

DOI: 10.6165/tai.2018.63.248

Photos by: M.A.K. Naive.

ABSTRACT

A new species, Cryptocoryne joshanii Naive & Villanueva, from the island of Basilan, Philippines, is herein described and illustrated. It is comparable to C. usteriana, but differs significantly in having lanceolate leaves, acicular, outwardly recurved, purplish red stigmas and an erect spathe limb. Information on the geographical distribution, ecological data, phenology and conservation status as well as an identification key to the Philippine Crytocoryne species are provided.

KEY WORDS: Aroids, Basilan, Cryptocoryne, Mindanao, New species, Sulu archipelago, Philippines.

Scale bar: C, D = 5 cm; E, F = 2 cm; G = 1 cm.

Cryptocoryne joshanii Naive & Villanueva, sp. nov.

Type: PHILIPPINES, Mindanao Region, Sulu Archipelago, Basilan Island, elev. 850 m, May 2013. R.J. Villanueva 001/2017 (holo HNUL, iso USTH) - Full locality data withheld owing to the risk of potential exploitation of wild populations for commercial purposes.

Diagnosis: Somewhat similar to C. usteriana in the spathe, but it differs significantly in having an acicular, outwardly recurved, purplish red stigmas and an erect smooth limb. The leaves are clearly different by being smooth, light green with markings.

Distribution: This Philippine endemic species has only been observed and documented in Sulu archipelago, particularly on the island of Basilan, Philippines. It is very local and despite of extensive survey along the stream and in other areas, it occurs only on the site where the sample was collected.

Ecology: The population of this species was found growing in a slow flowing montane forest stream in the interior of Basilan Island. The forest is relatively dense with only 40% sunlight reaching the stream bed. The population grows on volcanic rock in the stream several meters from the waterfall at elevations of about 800– 1000 m a.s.l. The roots and rhizomes were noted to penetrate deep into the pebble/sandy substrate rich with decaying leaves. The entire clump was submerged or partly submerged with leaves exposed.

Eponomy: Named after Joshan Vlad A. Villanueva, son of the discoverer/second author.

Notes: Based on overall morphology, Cryptocoryne usteriana, appears to be the closest ally of C. joshanii. However, C. joshanii differs significantly in having these following characters: lanceolate leaves, an erect apex of the limb and in having acicular, outwardly recurved, purplish red stigmas.

[Botany • 2018] Idimanthus amorphophalloides • A New Aroid Genus (Araceae-Caladieae) from Rio de Janeiro State, Brazil ---ScRaBBlE

Idimanthus amorphophalloides E.G. Gonç.

in Gonçalves, 2018

DOI: 10.11646/hytotaxa.351.1.8

Abstract

The monotypic genus Idimanthus (Araceae-Caladieae), represented by the species Idimanthus amorphophalloides, is here described and illustrated. It differs from all Caladieae by its connective ending in a rostrate beak turned downward, but the combination of cormous geophytic stem, copious endosperm, densely arranged fertile flowers and sterile flowers densely arranged in an apical appendix did not match any other genera in the tribe. It was collected in a marble outcrop in Northern Rio de Janeiro state, in the county of Italva, nearby the city of Cardoso Moreira as an understory herb. The aspect of leafless inflorescences with a long apical staminoidal area appearing directly from the soil is remarkably peculiar for Southeastern Brazilian aroids.

Keywords: Atlantic forest, geophyte, rocky outcrop, Monocots

Figure 2. Idimanthus amorphophalloides. leafy specimens covering the ground in the habitat.

Idimanthus E.G.Gonç. gen. nov.

Eponymy:–– The generic name honors Idimá Gonçalves da Costa, an active plant collector from Rio de Janeiro, which spotted this plant in the wild for the first time and cultivated it.

Idimanthus amorphophalloides E.G. Gonç., sp. nov.

Etymology:— The specific epithet aludes the resemblance with a miniature specimen of the aroid genus Amorphophallus, mainly because of its peculiar habit of flowering much before any sight of the leaves.
