Hanguana podzolicola (Hanguanaceae), a new record for Singapore [Page 157 - 165]
Hanguana podzolicola (Hanguanaceae), a new record for Singapore [Page 157 - 165]
Abstract:
Hanguana podzolicola (Hanguanaceae) is newly recorded for Singapore. Detailed colour plates are given alongside the main characters for distinguishing this species from the two most similar species in Singapore, Hanguana rubinea and H. triangulata. The seeds of Hanguana podzolicola are described for the first time. A local conservation assessment is given. As no original material of Hanguana podzolicola could be traced, a neotype is designated here. Following a recent clarification of several historical Hanguana names it is noted here that the correct name for the large helophytic stoloniferous species often cultivated in Singapore under the name Hanguana malayana is Hanguana anthelminthica. An updated key to Hanguana species in Singapore is provided.

Two new records of Litsea (Lauraceae) from Singapore and the lectotypification of twenty-two names from several Lauraceae genera [Page 167 - 177]
Two new records of Litsea (Lauraceae) from Singapore and the lectotypification of twenty-two names from several Lauraceae genera [Page 167 - 177]
Abstract:
Two species of Litsea (Lauraceae) are recorded for Singapore for the first time (Litsea spathacea Gamble and L. tomentosa Blume). Both species are known only from 19th century specimens and must be considered nationally extinct in Singapore. Descriptions and notes on distribution, conservation status and ecology are given. In addition, twenty-two Lauraceae names are lectotypified: Beilschmiedia curtisii Gamble, B. perakensis Gamble; Cinnamomum subavenium Miq.; Cryptocarya argentea Gamble, C. infectoria (Blume) Miq., C. tomentosa Blume; Lindera lucida (Blume) Boerl., L. malaccensis Hook.f.; Litsea accedens (Blume) Boerl., L. amara Blume var. attenuata Gamble, L. gracilis Gamble, L. gracilipes Hook.f., L. griffithii Gamble, L. lanceolata (Blume) Kosterm., L. machilifolia Gamble, L. machilifolia Gamble var. angustifolia Gamble, L. megacarpa Gamble, L. pustulata Gamble, L. sarawacensis Gamble, L.singaporensis Gamble, L. spathacea Gamble, L. umbellata (Lour.)

Novitates Bruneienses, 9. A synopsis of Epirixanthes (Polygalaceae) in Brunei Darussalam and notes on species elsewhere [Page 179 - 187]
Abstract:
The genus Epirixanthes Blume is revised for Brunei Darussalam. Four species are recognised for the country: Epirixanthes cylindrica Blume, E. elongata Blume, E. kinabaluensis T.Wendt and E. papuana J.J.Sm., with the two latter species being newly recorded for the Brunei flora. A single collection from Brunei that was formerly identified as Epirixanthes pallida T.Wendt is now confirmed as E. papuana. A revised key for the genus is included.

A new species of Zingiber (Zingiberaceae) east of Wallace’s Line [Page 189 - 199]
A new species of Zingiber (Zingiberaceae) east of Wallace’s Line [Page 189 - 199]
Abstract:
Zingiber Mill. is distributed from India to the Pacific but only a few species are known from east of Wallace’s Line, whereas the area to the west is rich in species. A recent collection from limestone at Bantimurung, South Sulawesi, Indonesia represents a new eastern species, Zingiber ultralimitale Ardiyani & A.D.Poulsen, which is described, illustrated, and barcoded using three of the four barcoding loci (rbcL, trnH-psbA and ITS). Placement of this species using morphological evidence is ambiguous but a combination of evidence from morphology, pollen anatomy and molecular analysis indicates that it belongs to Zingiber sect. Zingiber.

Contribution to a revision of Hoya (Apocynaceae: Asclepiadoideae) of Papuasia. Part I: ten new species, one new subspecies and one new combination [Page 97 - 147]
Abstract:
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 brassii P.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. koteka Simonsson & Rodda, H. stenakei Simonsson & Rodda, H. versteegii Simonsson & Rodda and H. yvesrocheri Simonsson & Rodda, one subspecies, H. juhoneweana ssp. lindforsiana Simonsson & Rodda, and make one new combination, H. urniflora (P.I.Forst.)

The taxonomic status of the presumed extinct Singaporean Hoya wallichii (Apocynaceae: Asclepiadoideae) [Page 175 - 187]
Abstract:
After critical study of type material and all available collections, the identity of Hoya wallichii (Wight) C.M.Burton as a species distinct from Hoya campanulata Blume is clarified. Hoya wallichii was previously considered to be endemic to Singapore but had become nationally extinct and consequently globally extinct. This study reveals, however, that it is also found in Peninsular Malaysia and Brunei and, even though it is still nationally extinct in Singapore, it is no longer globally extinct. Hoya campanulata is widespread and locally common in Sundaland but also nationally extinct in Singapore. The two species are fully described and illustrated by line drawings and colour photographs. Two conservation assessments are made, three names are lectotypified, and one name is epitypifed. This paper exemplifies how critical taxonomic understanding is fundamental to meaningful conservation assessments.

Novitates Bruneienses, 5. Polyalthia watui (Annonaceae), a new tree species from Brunei, Borneo [Page 71 - 76]
Abstract:
A new species, Polyalthia watui, is described. It resembles Polyalthia bullata King in having bullate leaves with a cordate base, but is distinguished by its flowers with shorter pedicels, longer sepals and petals, subsessile monocarps with long stiff erect hairs; and broad-obovate leaves with fewer pairs of secondary veins. The new species is only known from Brunei’s Belait and Tutong districts and is very likely endemic to the Belait geosyncline that includes these areas.

An expansion of the genus Deinostigma (Gesneriaceae) [Page 145 - 172]
An expansion of the genus Deinostigma (Gesneriaceae) [Page 145 - 172]
Abstract:
Based on molecular, morphological and cytological studies the previously monotypic genus Deinostigma W.T.Wang & Z.Y.Li has been expanded to include several species previously ascribed to Primulina Hance. Deinostigma now comprises seven species, including one previously placed in synonymy. The new combinations Deinostigma cicatricosa (W.T.Wang) D.J.Middleton & Mich.Möller, Deinostigma cycnostyla (B.L.Burtt) D.J.Middleton & H.J.Atkins, Deinostigma cyrtocarpa (D.Fang & L.Zeng) Mich.Möller & H.J.Atkins, Deinostigma eberhardtii (Pellegr.) D.J.Middleton & H.J.Atkins, Deinostigma minutihamata (D.Wood) D.J.Middleton & H.J.Atkins and Deinostigma tamiana (B.L.Burtt) D.J.Middleton & H.J.Atkins are made. Deinostigma eberhardtii is lectotypified. The genus is defined by a combination of an alternate leaf arrangement, hooked hairs on many plant parts, flowers with the pedicel inserted at an angle and off-centre on the receptacle, and, where known, a somatic chromosome number (2n) of < 36. This new circumscription of the genus expands its distribution from Vietnam into South China.

(Lauraceae) from Thailand and Indochina (Laos, Cambodia and Vietnam) is presented, comprising a key to species, full descriptions, distribution maps, provisional IUCN conservation assessments, ecological information and ethno-botanical notes where appropriate. In this treatment, 16 species are recognised, one species name is validated (Cryptocarya globularia Kosterm. ex de Kok), nineteen names are lectotypified and nine names are placed into synonymy for the first time. Using standard IUCN criteria, most species are considered to be Least Concern, one is assessed as Data Deficient (C. globularia), and six are Endangered (Cryptocarya chanthaburiensis Kosterm., Cryptocarya hainanensis Merr., Cryptocarya laotica (Gagnep.) Kosterm., Cryptocarya pallens Kosterm., Cryptocarya pustulata Kosterm. and Cryptocarya sublanuginosa Kosterm.).

A few last words on Far Eastern Dipterocarps [Page 357 -360]
A few last words on Far Eastern Dipterocarps [Page 357 -360]
Abstract:
Three additions to the Dipterocarpaceae are presented. Recent collections from southern Vietnam have finally revealed the identity of Dipterocarpus condorensis Pierre, necessitating reduction of D. caudatus Foxw. and nomenclatural adjustment of its subspecies; an unexpected novelty, Dipterocarpus pseudocornutus P.S.Ashton, is described from Tawi-Tawi, SW Philippines; while a new lower montane point endemic, Vatica palongensis P.S. Ashton, is reported from West Kalimantan.

A contribution to the systematics of Xylopia (Annonaceae) in Southeast Asia [Page 361 - 386]
A contribution to the systematics of Xylopia (Annonaceae) in Southeast Asia [Page 361 - 386]
Abstract:
Herbarium and field study of Xylopia L. (Annonaceae) for the Flora of Peninsular Malaysia and the Flora of Thailand projects has clarified regional diversity patterns within this ecologically significant lowland rainforest genus. Two species groups represented within Southeast Asian floras are delineated, one centred on Xylopia ferruginea (Hook.f. & Thomson) Baill. and the other on Xylopia malayana Hook.f. & Thomson. In the Xylopia ferruginea group, a new species, Xylopia erythrodactyla D.M.Johnson & N.A.Murray, is distinguished from X. ferruginea, and a new combination, Xylopia sumatrana (Miq.) D.M.Johnson & N.A.Murray, is proposed, based on an earlier name for the species currently known as Xylopia stenopetala Oliv. In the Xylopia malayana group, review of the species Xylopia elliptica Maingay ex Hook.f. & Thomson resulted in the recognition of three additional species: Xylopia platycarpa D.M.Johnson & N.A.Murray, from southern Thailand and northwestern Peninsular Malaysia, Xylopia ngii D.M.Johnson & N.A.Murray, from Peninsular Malaysia, Sumatra and Borneo, and Xylopia heterotricha D.M.Johnson & N.A.Murray, from Sumatra and Borneo. The taxon Xylopia malayana Hook.f. & Thomson var. obscura Kochummen is placed in synonymy under Xylopia elliptica sensu stricto. Xylopia fusca Maingay ex Hook.f. & Thomson var. sessiliflora Kochummen & Whitmore is distinguished from Xylopia fusca, and raised to species status as Xylopia sessiliflora (Kochummen & Whitmore) D.M.Johnson & N.A.Murray. We recognise 23 Xylopia species in the Sundaic region of Southeast Asia, and provide evidence that additional collecting and taxonomic analysis in the region is needed.

Studies in Southeast Asian Melastoma (Melastomataceae), 1. Morphological variation in Melastoma malabathricum and notes on rheophytic taxa and interspecific hybridisation in the genus [Page 387 - 401]
Studies in Southeast Asian Melastoma (Melastomataceae), 1. Morphological variation in Melastoma malabathricum and notes on rheophytic taxa and interspecific hybridisation in the genus [Page 387 - 401]
Abstract:
Morphological variation in the widespread Indo-Pacific Melastoma malabathricum L. is discussed, as well as the possibility of hybridisation or introgression with other species. Hypanthium indumentum is a reliable character to diagnose the group and species. Five rheophytic taxa, including four distinctive species and a variant of the widespread M. malabathricum, which are superficially alike because of their stenophyllous leaf form, are enumerated for Southeast Asia and a key is provided for their identification. Melastoma kahayanense K.M.Wong from Borneo is described for the first time and the Sumatran Melastoma stenophyllum Merr. is considered a distinct species and not synonymous to M. malabathricum. Various putative hybrids or introgression products involving M. malabathricum are identified.

Clarifying the nomenclature of Crateva trifoliata (Capparaceae) [Page 403 - 406]
Clarifying the nomenclature of Crateva trifoliata (Capparaceae) [Page 403 - 406]
Abstract:
Capparis trifoliata Roxb., the supposed basionym of ‘Crateva adansonii subsp. trifoliata (Roxb.) Jacobs’ and ‘Crateva trifoliata (Roxb.) B.S.Sun’, is shown to represent an illegitimate renaming of Crateva religiosa G.Forst. However, Jacobs effectively excluded the nomenclatural type of Capparis trifoliata, thus avoiding creating a superfluous name, and instead described Crateva adansonii subsp. trifoliata Jacobs validated by the citation of the Latin description of Crateva erythrocarpa Gagnep. Sun also excluded the type of Crateva religiosa, but his effective transfer of C. adansonii subsp. trifoliata to specific rank does not have priority over Crateva erythrocarpa Gagnep., which is therefore the correct name for this taxon when it is considered a distinct species. The name Crateva nurvula Buch.-Ham. is formally lectotypified.
