Abstract

LATIFF, N. A., SUKRI, R. S., & METALI, F. Nepenthes diversity and abundance in five habitats in Brunei Darussalam. Reinwardtia 14(1):  67 – 71. -- The genus Nepenthes is known to be diverse in Bornean forests and has been recorded in Brunei Darussalam in various forest types. We aim to investigate variation in Nepenthes species richness and abundance at five forest types throughout Brunei Darussalam: open secondary, heath, peat swamp, white sand and mixed dipterocarp forests. A total of thirty-nine 5 x 5 m2 plots were set up in these forest types. Within each plot, Nepenthes species abundance was quantified, with Nepenthes voucher specimens collected and identified to determine species richness. No significant differences were detected either for Nepenthes species richness or abundance between the five forest types, despite records of Nepenthes in Brunei showing preferences for particular habitat types. We suggest that average species richness and abundance remained constant regardless of forest types in this study, but that these results would likely change if sampling intensity is increased in future studies.

Abstract

In the area 20 species (one cultivated) are recognized; furthermore one undescribed species is discussed.The genera Cyelaiulrophora Hassk. and Mara/tithes Bl. are segregated from Parinari proper. The genus is subdivided into 2 sections: Parinari and Anareolala.

Abstract

Streblochaete Hochst. ex Pilg. (Gramineae) was not validly published in 1906, but in 1927. Koordersiochloa Merr. (1917) is therefore the correct name. Two new combinations are made.

Abstract

A key is given to 38 species of which 29 are either native or introduced in Malaysia; 9 others have been reported from Malaysia, but no material was found to justify these records. They have been marked by an asterisk before their number.Crotalaria grandiflora Reinw. has been reduced to C. tetragona Andr.C. lejoloba Bartl. is probably the oldest name for C.ferruginea Grah. ex Bth., but as no type material could be located the latter name has been maintained for the time being.Some sheets of the Philippines identified as C. acicularis Buch.-Ham. ex Bth. have proved to belong to C.humifusa Grah. ex Bth. which is a new record for these islands.C. medicaginea Lamk. and C. trifoliasU-um Willd.have sometimes been merged; they are kept apart in this paper.A new record for Malaysia is the African C. cleomifolia Welw. which has been introduced in the Malay Peninsula as a green manure; whether it has spread as a weed is uncertain.Another newly recorded species in Malaya is C.undtiella Lamk. collected in 1954 for the first time locally in abundance along the sandy beach.C. prostrata Rottl.is newly recorded for the Philippines.Among the species a few are indifferent to climate, but most apparently prefer the occurrence of a dry season in various degree. In mapping the areas it has been found that they can easily be arranged in the drought classes distinguished in the first instalment.An index to synonyms and a list of collectors numbers have been added at the end.

Abstract

In Malaysia the genus Orthosiphon has gained some general interest,because one of its species, well-known under its vernacular name kumis kutjing- or remukdjung, has been recognized as a noteworthy medicinal plant, besides being of some horticultural value.In the recent treatment by ADHLBERT in the emergency edition of Backers Beknopte flora van Java(1954) three species have been recognized, viz O. petiolaris MIQ., O. aristatiis (BL.) MIQ., and O. stamineus BTH. In my opinion the differences between the latter two are so small that they cannot be recognized as good species; in the herbarium they appear indistinguishable.My study has been based on the specimens in the Leyden and Utrecht herbaria.

Abstract

This is a fully descriptive account of the 108 species of Carex known to occur in Malaysia. They are arranged in three subgenera: Subgenus Indocarex Baill. (43 species), Subgenus Carex (Eucarex Coss. et Germ.) (57 species), and Subgenus Vignea (P. Beauv.) Nees (8 species). These are in turn divided into 33 sections. The classi- fication of these Malaysian Carices differs radically from past systems (cf. that of Kiikenthal, Engl. Pflanzenreich, 1909) and is based on the phylogenetic views of the author. Following the descriptions are citations of all the specimens seen by the author, and a few not seen but which have mainly been determined by Kiikenthal. The majority of the specimens Came from Bogor (Buitenzorg) (about 1500 sheets) and Leiden (about 600, including important historical specimens). About half of the species are restricted (endemic) to one or another of the island areas into which Malaysia can be conveniently divided: 18 species in New Guinea, 10 in the Philippines, 5 in Borneo and in Sumatra, 4 in the Malay Peninsula, 3 in Java and in Celebes, 2 in the Moluccas, and 1 in the Lesser Sunda Islands. The remaining 58 species have a slightly to much wider distribution, the chief connection being with India, and, to a slightly less extent, Japan and China. Keys are provided to the species as a whole, to the subgenera, the sections, and to the species in each section. The introductory part of the work explains, among other things, the classi- fication, the relative taxonomic value of characters in the descriptions, distribution, and sources of the material,.

Chydenanthus is accepted as a monotypic genus and its type species C. excelsus (Bl.) Miers is redescribed. C. dentato-serratus R. Knuth belongs to Barringtonia and is thus excluded from the genus.

Abstract

Since a large number of characters are now known for Freycinetia Gaudich. and Pandanus Parkinson species, it appears useful to consider their use in identifying plants from Java. Fieldwork carried out for this study has provided stronger foundation for understanding morphological variation within the species. This study was undertaken to have a better understanding on the morphology of the family in order to make a better species delimitation. Characters of habit, stem, leaves, auricles, bracts, peduncle and pedicel, inflorescence, staminate flowers (male), pistillate flowers (female), cephalia and berries were found useful in delimitation and identification of Javanese Freycinetia, while characters of habit, stem, prop root, marginal spine, leaves, bracts, inflorescentia, peduncle, staminate flowers (male), pistillate flowers (female), cephalia, drupes were found to be useful for distinguishing among species of Javanese Pandanus.
