Savinov (Laos, Thailand), a new record for China, G. tonkinense Pitard (SE Yunnan) and a new record for Cambodia, G. quadrangulare Prain ex King, a new record for Indonesia - G. euonymoides Merr. and a new record for Philippines, Mindanao island - G. loheri Merr.

Abstract

We studied the floristic composition and structure of the logged-over peat swamp forest in the PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been set aside by the company. In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect, thus covering a sampled area of 1-ha. The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness. The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth. Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high (3.05) Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46 %). The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium and based on this association combined with high IVs, the two parameters of species characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and Gonystylus bancanus vulnerable, hence they should be protected.

Abstract

Cercospora brunfelsiicola on Brunfelsia uniflora is proposed as a new species based on a combination of molecular phylogenetic and morphological data analyses. The molecular phylogenetic analysis based on combined multilocus analyses of the Internal Transcribed Spacer (ITS), part of the elongation factor 1–a gene (EF1–a), and part of the calmodulin (CAL) gene regions showed that C. brunfelsiicola is phylogenetically distinguishable from other Cercospora species, including members of the C. apii s. lat. complex. Morphologically, C. brunfelsiicola differs from other closely related Cercospora species, in particular C. acaciae-mangii, by forming lesions with indistinct margin, larger stromata [(32) 48.5 ± 10.6 (68) ?m diam.], and filiform to narrowly obclavate conidia [(45) 59 ± 9.1 (72) × (2.5) 2.5 ± 0.2 (3) ?m].
FLORA OF BALI: A PROVISIONAL CHECKLIST Max M. J. van Balgooy; Elizabeth Anita Widjaja

Abstract

Compared to Java the flora of Bali is poorly known. A checklist has been prepared based on literature and collections. The focus is on indigenous species, but the distinction between indigenous and naturalized species is not always clear. This checklist is therefore very provisional. The flora of the much smaller island state Singapore is much richer, probably mainly due to undercollecting of Bali.

Abstract

Cross sections of leaves of Pandanus spp. showed that their leaf anatomy is similar, whilst paradermal sections indicated that crystal numbers differ. Variation was found in the anticlinal epidermal cell walls, stomata, hypodermis, sclerenchyma, mesophyll and crystals, as discussed in this paper.

Abstract

A total of 126 species are currently named and described from Borneo (Brunei - 16 species, Kalimantan – 5 species, Sabah – 41 species and Sarawak – 72 species). However, based on our survey of the begonia collection in the Sarawak Herbarium, the un-named taxa (about 110 species) significantly outnumber the 72-named species. The situation is probably the same for Sabah, so with many more new species than the 41 named ones at a conservative estimate the Sabah begonia flora can be expected to exceed 100 species. For Kalimantan (5 named species), the total number of un-named species is likely to be even higher considering that Kalimantan occupies a larger land area, its begonia-rich mountains and limestone areas are hardly collected, and the begonia flora has hardly been studied at all. We can therefore expect the begonia flora of Borneo to exceed 600 species. In view of the high level of narrow endemism (80% of species are known from a single locality), expeditions to unexplored areas are necessary to document, in particular, areas that are experiencing irreversible land-use change. Alpha-taxonomy on a large scale is needed to tackle the backlog of literally hundreds of new undescribed species.

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.
