Abstract

GRADSTEIN, R. et al. 2010. Bryophytes of Mount Patuha, West Java, Indonesia. Reinwardtia 13(2): 107-123. - This paper presents the results of a two-day survey of the bryophyte flora of Mt. Patuha and its surroundings near Bandung, West Java, carried out in the framework of the 5th regional training course on bryophyte and lichen diversity and conservation organized by SEAMEO BIOTROP, Bogor, in July 2009. A total of 159 bryophyte species were identified, including 98 mosses, 60 liverworts, and 1 hornwort, representing almost 1/6 of the total bryophyte flora of Java. Three moss species, Bryohumbertia subcomosa (Dix.) J.-P. Frahm, Fissidens gymnogynus Besch. and F. polypodioides Hedw., and one liverwort, Lejeunea pectinella Mizut., are new additions to the Javanese flora. The bryophyte diversity of Mt. Patuha is well representative of the Malesian flora and is rich in uncommon species. However, the relatively poor representation of shade epiphytes and commonness of sun epiphytes and generalists reflect disturbance of the forest by anthropogenic activities. Careful attention should be given to conservation of the remaining natural forest in order to prevent further losses of the rich bryophyte diversity of the area.

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 collector's numbers have been added at the end.

Abstract

POWLING, A. 2018. An assessment of present plant diversity on the Natewa Peninsula, Vanua Levu, Fiji. Reinwardtia 17(2): 125‒132. ‒‒ The Natewa Peninsula, part of the Fijian island of Vanua Levu, is naturally afforested but the forests have been extensively logged in the last 50 years. It is now planned to protect some of the forests from further logging by incorporating them into a National Park. A survey of plant species in the regenerating forests and surrounding land on the Peninsula was performed to assess the taxonomic and ecological diversity of the trees and shrubs, including figs and palms, and also the orchids presently to be found on the Peninsula. The degree of invasion by introduced plant species was also assessed. Of 67 tree and shrub species it was found that 17 were endemic to the Fijian islands, 40 others were indigenous and ten were introduced. The normal habitats of these species included dense, open and secondary forest, showing that trees with a range of ecological characteristics were still present. Endemic and indigenous species of both figs and palms were found, and also terrestrial and epiphytic orchids. No severe infestations of introduced species were observed. It is concluded that the forests of the Peninsula are of sufficient conservation value to justify National Park status. 
CODONOBOEA (GESNERIACEAE) SECTIONS IN PENINSULAR MALAYSIA Chung Lu Lim; Ruth Kiew

Abstract

Codonoboea is the largest genus of Gesneriaceae in Peninsular Malaysia with 92 species. Nine sections, Boeopsis, Codonoboea, Didymanthus, Glossadenia, Heteroboea, Pectinati, Reptantes, Salicini and Venusti, have been erected based on morphological characters, such as habit, leaf arrangement and shape, type of inflorescence, number of flowers, corolla type and nectary type. Recent molecular phylogenetic study using ITS and trnL-F sequences show that only section Heteroboea is monophyletic. While the sections of Codonoboea can no longer be maintained as formal taxonomic taxa, as informal groupings they are useful in identification and in constructing keys.

Abstract

LATIFAH, D., CONGDON, R. A. & HOLTUM, J. A. 2016. Growth responses of palm seedlings to different light intensities stimulating canopy gaps with an ecophysiological approach. Reinwardtia 15(2): 81 – 98. — Palms (Arecaceae) mainly grow in rainforests and many occur in disturbed areas like canopy gaps created by natural disturbances such as cyclones in Australia. Knowledge of seedling growth in different light intensities is essential to assist rainforest restoration in disturbed or marginal lands. The aim of this research was to investigate the effects of different light intensities on the seedling growth of Arenga australasica (H. Wendl. & Drude) S. T. Blake ex H. E. Moore, Calamus australis Mart., C. moti F. M. Bailey, Hydriastele wendlandiana (F. Muell.) H. Wendl. & Drude and Licuala ramsayi (F. Muell.) H. Wendl. & Drude. Seedling growth experiments (pot trials) were conducted in a glass house using shade cloth providing four different levels of shading: 59, 29, 17 and 6% sunlight. The growth rate, leaf turnover, leaf area, total chlorophyll, chlorophyll a:b ratio, vigor, above-ground and below-ground biomass and growth indices (LAR, SLA and LWR) of palm seedlings were measured. As a result of these measurements the relative shade tolerance of the five species was determined. The seedlings of Arenga australasica were classified as intermediate-shade intolerant species. Hydriastele wendlandiana seedlings were shade-intolerant. Calamus australis and C. moti seedlings are intermediate-shade intolerant. Licuala ramsayi seedlings were found to be a shade-tolerant.

Abstract

A historical sketch of the genus Catantlicra is presented and its relationship with the two allied genera Dissockaeta Bl. and Mediniltu Gaud, is discussed. The 16 species recognised in the genus Cntantkcra are described and a key to the species so far known is presented. The genus Cata-nthera is entirely restricted to Malesia, occuring in New Guinea, Borneo and Sumatra. They are ivy-like climbers which form a canopy in the tropical rain forests. Five new species, Catanthera royenii Nayar, C. pifosa Nayar, C. novoguinevnsis Nayar, C. Hleuineri Nayar and C. peltata Nayar are described and illustrated.
