Studies on Schismatoglottideae (Araceae) of Borneo XXXIV β The Fruits of Schottariella mirifica
The fruits of Schottariella mirifica P.C. Boyce & S.Y. Wong are described and illustrated for the first time and shown to be dehiscent berries, the second recorded example of this fruit type for tribe Schismatoglottideae, and the third for the family Araceae. The berries of Schottariella mirifica dehisce basally with the shed portion of the berry
containing 3β5 comparatively large seeds, each fully enclosed in a fleshy white aril
Studies on Schismatoglottideae (Araceae) of Borneo XXVI β Schismatoglottis scintillans, a new species with horticultural potential from Sabah, Malaysian Borneo
Schismatoglottis scintillans Scherberich & P. C. Boyce sp. nov., a taxonomic novelty with horticultural potential, is described from Sabah, Malaysian Borneo. Schismatoglottis scintillans belongs to the Calyptrata Group by the presence of hapaxanthic shoot modules, but differs from all species hitherto described for this Group by the combination of refractive variegated leaf blades, a pistillate flower zone extensively adnate to the spathe, a staminate flower zone only half exserted from the lower spathe portion, and a bullet-shaped appendix basally abruptly wider than the adjacent top of the staminate flower zone. The new species is keyed out and illustrated from living plants
Studies on Monstereae (Araceae) of Peninsular Malaysia I: Rhaphidophora megasperma, a New Record for West Malaysia
Rhaphidophora megasperma Engl., a species hitherto regarded as endemic to Sarawak, East Malaysia, is published as a new record for Peninsular Malaysia. It is the first species in the Rhaphidophora Spathacea group recorded for western Sunda. The species is illustrated and a key to the perforate-laminated Rhaphidophora in Peninsular Malaysia is presented
Studies on Schismatoglottideae (Araceae) of Borneo LVIII : Further novelties described for the genus Piptospatha, and a note on Piptospatha Sect. Gamogyne
Piptospatha bella S. Y. Wong & P. C. Boyce
and Piptospatha lurida S. Y. Wong & P. C.
Boyce are described and illustrated from
Sarawak, Malaysian Borneo. Their
recognition takes Piptospatha to 18 described
species. Piptospatha lurida is most similar to
P. burbidgei, a species formerly allotted its
own genus, Gamogyne, later made into a
section of Piptospatha. Notes on Gamogyne
are provided and a correction to published
information on the placentation of
Gamogyne offered
Schismatoglottideae (Araceae) of Borneo XIX β Piptospatha pileata, a remarkable new species from Kalimantan Timur, Indonesian Borneo
Piptospatha pileata, a new species of the Araceae tribe Schismatoglottideae from Kalimantan Timur province, Indonesian Borneo, is described, comparatively illustrated and delimited from P. burbidgei and P. elongata, and included in a revised key to the species of the genus
The Araceae of Indomalaya I: Piptospatha N.E.Br.
A review of the genus Piptospatha
N.E.Br. is presented with new generic
boundaries implemented since the last full
revision. 10 species are recognized, two of
them (P. marginata (Engl.) N.E.Br. & P.
repens H.Okada & Tsukaya) recognized
only recently as distinct species. Two
species (P. angustifolia Engl. ex Alderw.
and P. remiformis Ridl.) are treated as
inadequately known. A key to accepted
species is given, and all species are
illustrated, the majority from living plant
Studies on Schismatoglottideae (Araceae) of Borneo XXIX - Piptospatha manduensis-The Ultimate aroid calciphile ?
Piptospatha manduensis A. Hay & Bogner is highlighted as a truly calciphilous aroid obligated to travertine in north eastern Indonesian Borneo. Based on new collections and cultivated plants an updated description is offered. A brief overview of the other very few calciphilous aroids in Borneo is presented, and together with P. manduensis, all are illustrated
Studies on Homalomeneae (Araceae) of Borneo XV: A Novel Limestone-Obligated Homalomena from SW Sarawak, Malaysian Borneo
Homalomena selaburensis P.C.Boyce & S.Y.Wong is described as a taxonomic novelty of the Homalomena Supergroup from forested Karst limestone in Samarahan Division, SW Sarawak, and compared with the most similar species described so far from Sarawak (Homalomena passa S.Y.Wong & P.C.Boyce), and from Peninsular Malaysia (Homalomena curvata Engl.). An identification key is provided and Homalomena selaburensis is illustrated from living plants
Studies on Schismatoglottideae (Araceae) of Borneo XXXIV β Schismatoglottis iliata, a new species from NW Sarawak, and notes on the Schismatoglottis Multiflora Group and the Schismatoglottis mayoana Complex
A summary of the Schismatoglottis Multiflora Group of Hay & Yuzammi is presented and the group shown to comprise about 15 species, including that described here. Schismatoglottis iliata P. C. Boyce & S. Y. Wong is described as a taxonomic novelty from forested sandstone riverside bluffs of the Ulu Batang Kayan, Lundu District, Kuching Division, NW Sarawak, Malaysian Borneo, and compared with the morphologically most similar species, S. mayoana Bogner & M. Hotta and S. nicolsonii A. Hay, with which S. iliata shares leaf blades adaxially matt olive green and abaxially with very fine and dense (c. 2 veins per mm) pellucid secondary venation, and stamen thecae each with two pores. A key to this newly recognized S. mayoana Complex is provided, and all described species for the S. mayoana Complex are illustrated
Studies on Schismatoglottideae (Araceae) of Borneo LVII: Bucephalandra filiformis β a new species from Maligan, Sarawak, Malaysian Borneo
Bucephalandra filiformis is described as a
new species with uniquely stiff linear leaf
blades, illustrated from living plants from
the Maligan Range (Sarawak & Sabah,
Malaysian Borneo), and inserted into the
most recent identification key to
Bucephalandra species
