Nephelaphyllum is a relatively small genus, containing only 11 species distributed from China through Indochina to Thailand and from Peninsular Malaysia eastwards through Indonesia to the Philippines (Chan et al. 1994). The species are easily recognised, even when not in flower, by their characteristic light green or yellowish leaves and dark green venation and blotches (Comber 1990). All species grow in deep, well-drained humus in dark conditions on the forest floor, especially in areas without severe dry seasons (Comber 1990).

As part of current research on the taxonomy of the palms (Arecaceae or Palmae) of New Guinea, ten new species of the rattan genus Calamus are described and illustrated here: Calamus baiyerensis, Calamus capillosus, Calamus erythrocarpus, Calamus heatubunii, Calamus jacobsii, Calamus katikii, Calamus kostermansii, Calamus papyraceus, Calamus pintaudii and Calamus superciliatus. An eleventh species, Calamus novae-georgii, from the neighbouring Solomon Islands is also included here. The palm flora of New Guinea now includes 62 species of Calamus, 34 of which have been described since 2002, demonstrating the remarkable scale of botanical discovery on the island.
Key words: Calamoideae, Indonesia, lianas, Palmae, palms, Papua New Guinea, Papuasia, South-East Asia

The large majority of Hoya R.Br. species known from Papuasia were described in the first half of the 20th century and most of these are endemic. Along with Borneo and the Philippines the region is a centre of diversity of the genus. Since 2006 herbarium materials have been studied for a revision of Hoya of New Guinea along with field investigations on Papuasian Hoya since 2010. In the present paper we publish ten new species,Hoya brassiiP.I.Forst. & Liddle ex Simonsson & Rodda, H. carrii P.I.Forst. & Liddle ex Simonsson & Rodda, H. edholmiana Simonsson & Rodda, H. evelinae Simonsson & Rodda, H. juhoneweana Simonsson & Rodda,H. krusenstierniana Simonsson & Rodda,H. kotekaSimonsson & Rodda,H. stenakeiSimonsson & Rodda, H. versteegiiSimonsson & Rodda and H. yvesrocheri Simonsson & Rodda, one subspecies,H. juhoneweana ssp. lindforsiana Simonsson & Rodda, and make one new combination, H. urniflora(P.I.Forst.) Simonsson & Rodda, which is also lectotypified.

A new species, Brownlowia latifiana (Malvaceae-Brownlowioideae), endemic to Terengganu, Peninsular Malaysia, is described and illustrated. This new species has most of its morphological characters that are related to those of the genus Jarandersonia. Therefore, a standard morphological taxonomic revision and morphometric analysis were carried out to assess the status of Brownlowia latifiana. Results of the morphometric analysis based on morphological characters showed that Brownlowia latifiana is embedded within the clades of Brownlowia but distanced from the clades Jarandersonia. Brownlowia formed a distinct clade in the clustering tree well separated from the Jarandersonia. A distribution map and a conservation assessment using the IUCN Red List categories and criteria are provided.
Keywords: Conservation, endemic, flora, Malaysia, taxonomy, Malvaceae, Eudicots

Brownlowia latifiana R.C.K.Chung, sp. nov.
Type:— PENINSULAR MALAYSIA. Terengganu: Dungun, Jerangau Forest Reserve, buffer zone by the stream of Compartment 95, 65 m altitude, 21 July 2009 (flowers and fruits), Y.C. Chan & C.L. Lim FRI 65055 (holotype KEP [barcode 246218]; isotypes A, K).
Brownlowia latifiana is closely related to B. argentata and B. tersa in leaf texture, type of indumentum and other flower and fruit characters. However, the former differs from the latter, B. argentata and B. tersa, by its narrowly elliptic leaves (vs. ovate to broadly ovate or lanceolate), glabrous beneath (vs. densely covered with scales), 10−20 pairs lateral veins (vs. 4−10), large transversely ellipsoid fruits (vs. small depressed obovoid), absence of androgynophore (vs. presence and elongated to 6 mm long, 3 mm thick), persistent calyx lobes (vs. absent), and thick fruit stalk (vs. thin stalk). The main morphological differences between these three species are shown in Table 3.
.....
Etymology:— This species is named after the current Director-General of Forest Research Institute Malaysia (FRIM), Dato’ Dr Abd. Latif bin Mohmod, for his contributions in securing fund of RM7.6 million for the Project of Safeguarding the Forest Plant Diversity of Peninsular Malaysia under the Ninth Malaysian Plan; successfully in acquiring the ownership of FRIM land area of 544.3 ha from the Selangor State Government in 2007; and in obtaining the recognition for FRIM as the Natural Heritage Site in 2009 and the National Heritage in 2012.
Distribution and habitat:— This species is endemic to Peninsular Malaysia, known from Jerangau Forest Reserve and Sg. Jerangau in Dungun, Terengganu. It occurs in undulating and riverine areas of lowland dipterocarp forest on clay sandy and alluvial soils at about 65 m elevation.

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 dauaeN.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 Vietnamocasiadauae 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.

Two new Orchidantha species discovered in Sarawak, Orchidantha micrantha and O. megalantha, are described and illustrated. They may well represent the species with the smallest and the largest flowers currently known in the genus and certainly from Borneo. With its small flowers, O. micrantha is similar to O. borneensis to which it is compared. The large-flowered O. megalantha is compared to the morphologically closest species, O. holttumii, from nearby Brunei. The conservation status of both new species is assessed and a key is provided to all Bornean species.

Orchidantha micrantha only known from Kubah NP, Sarawak, Borneo (Poulsen & Leong-Škorničková, 2017. Blumea.62: 157). The flower is the SMALLEST of all species of Lowiaceae. Like its big sister, O. megalantha, its smell may attract pollinating dung beetles.
Etymology. The epithet refers to the small flowers relative to other species of the genus.
Orchidantha megalantha from Mulu National Park, Sarawak, Borneo. We described it recently in the journal Blumea. The flower is the largest of the family Lowiaceae and its putrid smell may attract dung beetles to pollinate it.
