ABSTRACT
In Peninsular Malaysia, Coleus is represented by five species. Two, C.hairulii Kiew and C.rafidahiae Kiew, are new species. Both are narrowly endemic and restricted to limestone hills as is C.kunstleri (Prain) A.J.Paton. All three are Critically Endangered. Coleusscutellarioides (L.) Benth., although widespread, is probably not indigenous. It is also a common ornamental, while C.monostachyus (P.Beauv.) A.J.Paton is a recent introduction that has spread rapidly and threatens to become a troublesome weed.
ABSTRACT
Vatica najibiana Ummul-Nazrah (Dipterocarpaceae), from the Relai Forest Reserve, Gua Musang, Kelantan and Gua Tanggang, Merapoh, Pahang, is described and illustrated. This species is Endangered and known from small populations restricted to two isolated karst limestone hills. The type locality, Relai Forest Reserve limestone, is currently under threat from encroaching oil palm plantations and ongoing logging, which, if it continues, will threaten the Kelantan population with extinction. The morphology of V. najibiana and the similar V. odorata subsp. odorata and V. harmandiana is compared.
ABSTRACT
Two new species, Phlegmariurus iminii Kiew (Lycopodiaceae) from limestone karst and P. monticola Kiew from montane habitats, are described from Peninsular Malaysia and a new combination is made for Phlegmariurus pinifolius (Trevis.) Kiew. Phlegmariurus iminii, known from a single hill threatened by quarrying, is Critically Endangered; while P. monticola and P. pinifolius that are relatively widespread are of Least Concern.
ABSTRACT
A new species of Asplenium is described from two collections made on limestone hills in Peninsular Malaysia. Conspicuous by its extremely narrow pinnae, it is probably allied to A. salignum but differs in sufficient characters (scale size, size and shape of lamina, venation and sorus length, position and orientation) to be a species in its own right.
