查看更多>>摘要：Rhaphidophora latevaginata M.Hotta, a neotenic, shingling, climbing aroid, hitherto considered a Bornean endemic, has recently been found and collected from the southern part of the east coast of Peninsular Malaysia (Johor: Kota Tinggi and Mersing), where so far it appears to be restricted to kerapah and the drier (raised podzol) facies of seasonally inundated peatswamp forest. This discovery of R. latevaginata takes to 18 the number of Rhaphidophora known to occur in Peninsular Malaysia, of which three are endemic. An updated description of R. latevaginata, a key to the Rhaphidophora species of Peninsular Malaysia, and a plate illustrating the diagnostic characters of those with shingle-stage juveniles is presented. A brief note on the significance of the new record with regard the Riau Pocket is made.

It has recently been discovered and collected from several localities in southern Peninsular Malaysia, representing both a new record for Malaysia, and through clonal propagation via various tissue culture techniques would supply a sustainable potential source of a local commercial ornamental horticultural product. An enlarged description of S. lucens, and a key to the Peninsular Malaysian Scindapsus are offered. A plate illustrating the diagnostic characters of S. lucens is given.

查看更多>>摘要：Endiandra trees are not frequently encountered in the forest in Indonesia. Recent exploration in Waigeo Island resulted in the collection of three species of Endiandra. All three species were collected for the first time from Waigeo Island. The three species are restricted in distribution to eastern part of Indonesia (Papua Province) and Papua New Guinea. Key to the species and species description are provided.

The five species of Marasmius are M. cf. purpureostriatus, M. guyanensis, M. coklatus var. mentarangensis, var. nov., M. caryote var. pa'rayeensis, var. nov., and M. gypseus, sp. nov. Comprehensive descriptions, illustrations, and comparison with similar taxa are presented.

查看更多>>摘要：The subfamily Ptychanthoideae of the family Lejeuneaceae (Hepaticae) in West Java is still poorly known. A study of Ptychanthoideae in this area reveals the occurrence of 26 species, in 8 genera: Acrolejeunea (Spruce) Schiffn. (3 species), Archilejeunea (Spruce) Schiffn. (1 species), Lopholejeunea (Spruce) Schiffn. (10 species), Mastigolejeunea (Spruce) Schiffn. (3 species), Ptychanthus Nees (1 species), Schiffneriolejeunea Verd. (2 species), Spruceanthus Verd. (2 species) and Thysananthus Lindenb. (4 species). Mastigolejeunea indica and Thysananthus minor are newly reported for Java. The altitudinal and geographical ranges of the species of Ptychanthoideae from West Java are presented as well as a key to the species and an assessment of their phytogeography. It appears that the species are rather widespread; none of the species are endemic to Java or western Malesia. The widespread distribution of the species is probably due to their dispersal by spores, which may be easily carried by the wind over long distances, and by the rather old geological age of the group.

查看更多>>摘要：Two new combinations are made here: Haplopteris hirta (Fee) S.Linds. and Haplopteris angustissima (Holttum) S.Linds. In preparation for the account of the Adiantaceae for the Flora of Peninsular Malaysia new combinations are necessary in the genus Haplopteris C.Presl. The family delimitation to be used in the Flora account is modified from Smith et al. (2006, 2008) who recognized a broadly delimited Pteridaceae but acknowledged that there are five monophyletic groups within the family that could be raised back to family level. The Adiantaceae, comprising Adiantum L. and all members of the former family Vittariaceae, is one of these monophyletic groups. As so defined, the Adiantaceae in Peninsular Malaysia consists of the five genera Adiantum L., Antrophyum Kaulf., Haplopteris C.Presl, Monogramma Comm. ex Schkuhr., and Vaginularia Fee. The generic delimitation of the Vittarioid genera in the Flora account will largely follow Crane (1998). In this work it was shown that the Old and New World Vittaria species did not form a monophyletic group. All Vittaria species in Peninsular Malaysia (see Holttum, 1955) now belong in the genus Haplopteris. Crane (1998) and Zhang (2003) made most of the necessary name changes but two new combinations are still required.
