Abstract

New species are described in Cinnamomum (12), Cryptocarya (8), Endiandra (2) and Litsea (1). New combinations are proposed in Actino-daphne (1), Cinnamomum (20), Endiandra (1), Litsea (1), Neolitsea (1). Moreover new names are proposed in Cryptocarya (1) and Litsea (7). The generic name Kubitzkia van der Werff is considered invalid and numerous species are reduced to synonymy for the first time.

Abstract

KARTAWINATA, K., PURWANINGSIH, PARTOMIHARDJO, T., YUSUF, R., ABDULHADI, R. & RISWAN,S. 2008.Floristics and structure of a lowland dipterocarp forest at Wanariset Samboja, East Kalimantan, Indonesia.Reinwardtia 12(4): 301– 323. — The results of a floristic inventory of trees with DBH < 10 cm in a lowland dipterocarp forest in East Kalimantan show that 553 species of 192 genera in 62 families, represented by 5847 individuals, with the total basal 2 area of 350.01 m occurred in the plot of 10.5 hectare sampled. The two leading families in terms of number of species were Myrtaceae and Lauraceae while according to the total sum of importance values for families were Dipterocarpaceae and Euphorbiaceae. The forest had the second highest species richness in Indonesia. We recorded 225 species of dipterocarps , constituting 4.53 % of total species with basal area of 85.53 m . or 24.44 % of the total basal area in the plot. Shorea laevis (a diptererocarp) and Pholidocarpus majadum, (a palm) were the most prominent species occurring here and were two of the ten leading species. The species-area curve rose steadily even up to an area of 10.5 hectare, with a very slight indication of levelling off at about five hectares, indicating high heterogeneity of the forest. Three largest trees were Shorea pauciflora (DBH = 196.50 cm) Dipterocarpus cornutus (DBH = 170.90 cm), and Alstonia scholaris (DBH = 170.00 cm) , Some species could be identified as fruit trees and medicinal plants.

Abstract

Palms (Arecaceae) are an important component of many tropical rainforests. Many have also been cultivated widely for agricultural commodities with high economic value. They are also important components in rehabilitation of disturbed or marginal lands. Knowledge and application of germination strategies are essential in the cultivation of palms. Many species have seeds that do not germinate readily, even when light conditions are favourable. This research determined the effects of seed coats, light and temperature on germination of Arenga australasica (H. Wendl. & Drude) S. T. Blake ex H. E. Moore, Calamus australis Mart., Hydriastele wendlandiana (F. Muell.) H. Wendl. & Drude and Licuala ramsayi var. tuckeri Barford & Dowe. We examined physical treatments to promote germination or break dormancy, as well as different light and temperature conditions. The results showed that the hard seed coats of the four species slowed imbibition. Scarified seeds germinated best for A. australasica, C. australis and L. ramsayi. The germination of all seeds was inhibited by far red light. The red light requirement suggests that these species prefer to colonise open areas. This implies that dispersal agents, canopy gaps and forest margins may play important roles in promoting regeneration as well as conservation of these palm species.

Abstract

1. In this continuation of the authors nomenclatorial enumeration not only the three families mentioned in the subtitle are taken into consideration: about ten generic names of fungi which at one time or another have been attributed to the Exobasidiaceae and which are now excluded from the Hymenomycetes, are also dealt with.2. The name Cryptobasidiaceae is validly published.

Abstract

A monograph of Pometia, which extends from Ceylon throughout Malaysia to Samoa, with a few stations in SE. Asia and Formosa. Two species are recognized: P. ridleyi and P. pinnata, the latter having a particular pattern of alternating- nerves. Pometia pinnata is extremely variable and clearly still in process of differentiation. From the wealth of forms, 8 formae have been selected for taxonomic recognition, 1 of them is newly described, 7 are new combinations; characters are found in the leaves and the inflorescence. Besides, a number of unnamed paramorphs have been described. The distribution of the variability has been sketched for each region. Details about ecology etc. are given. Specimens are cited where appropriate and a general Identification List is given at the end.

Abstract

Using the Braun-Blanquet and ordination techniques, nine dry-grass community types were recognized on Oahu,seven of which were dominated by exotic grasses and two by native grasses, Hctcrnpogna eontortus and Erarjrostis variabilis.These community types occured in summer-drought, summer-dry and humid climates.The distribution of certain community types could be correlated directly with rainfall and soil pH. In the summer-drought climate the occurrence of the community types was related to topography,wind exposure, rockiness of the land surface and stoniness of the soil.The nine community types were not related to the established soil series, organic matter content and watsr retaining capacity of the surface soils.Three distinct soil-water regimes were recognized in five community types: drought, dry and wet types.Seasonal variations in soil-water content were correlated closely with the rainfall pattern.The introduction and spread of exotic species resulted in a gradual disappearance of the native grass communities in the summer-drought zone. In the summer-dry zone, Grevillea robiista. trees and Meliiiis minutiflora grass mats were invading the Rhynchelytrum repens community. Artdropogon virginiciis, introduced in 1932, formed a wide spread herbaceous community in the humid zone. In some places, this community was invaded by Dicranopteris linearis fern mats and trees of Acacia, koa or Metrosideros collina. Fire in both the summer-dry and humid zones maintained and extended the grass communities.
