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

The Heart of Borneo (HoB) declaration is a conservation agreement initiated by WWF and signed by three countries, i.e., Brunei Darussalam, Indonesia and Malaysia in Bali, Indonesia on 12th February 2007 to protect more than 23 million hectares of forested region on Borneo Island. These forested areas could be well protected when conservation management plan is in place. One of the crucial activities to facilitate the planning and formulation of conservation plan is to conduct scientific expeditions that include botanical exploration. The primary objective of the expedition is to identify the key conservation targets within the forest reserves. For the past five years, several expeditions have been conducted by the Sabah Forestry Department under the auspices of the HoB project to explore various forest reserves with conservation issues within the Heart of Borneo area. This paper will present the findings which include plant richness, endemism and plant conservation status in each forest reserves that has been explored.

Abstract

Two new species of Begonia, Begonia holosericeoides Ardi & D. C. Thomas and B. aketajawensis Ardi & D. C. Thomas, are described from Aketajawe Lolobata National Park, Halmahera, Indonesia. The two species belong to Begonia section Petermannia. Begonia  holosericea, previously only tentatively assigned to a section, is here assigned to section Petermannia based on the examination of newly available material. Additionally, a revised description and an illustration are provided. A key to the Moluccan species of Begonia is presented.

Abstract

The identity of Uvaria nitida Roxb. ex G.Don. (Annonaceae) has not been considered for 180 years. The plant is only known from material grown in the Calcutta Botanic Garden in India following introduction from, reportedly, the Moluccas. Examination of a specimen from the Brussels Herbarium, designated here as lectotype, indicates that the species is a member of Orophea subgenus Sphaerocarpon, similar to Orophea gabra Merr. A new combination in Orophea is made.

Abstract

Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarifyvegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 x 10 m2 in abandoned plantation and 11 of 20 x 20 m2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swieteniamacrophylla –Agathisdammaa community in abandoned plantation where had a land use history of clear felling.Maesopsiseminii–Cyathea spp. community had a history of severe human disturbance. Fagaceae-Schimawallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses, and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery.

Abstract

Local communities have their own means of maintaining their traditional know-ledge and sustaining the production system of natural resources by designating the resources as sacred. Without the states influence, local people have their own strategies to conserve the environment and resources, in ways which are more effective than those enforced by the state. A study done through interview, participatory observation, and ethnographic methods revealed that local people recognized two models of natural resources conservation. The first model is the designation of forests as sacred site, aiming at maintaining the sustainability of ecosystem and the second model refers to adoption of species as a sacred entity to sustain production system. Dynamic processes are operating in the sacredness of both forest and species.

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

The Lesser Sunda Islands of Indonesia are composed of small islands scattered from Bali to Timor Island. We analyzed a molecular phylogeny of Adiantum collected from Lesser Sunda Islands to reveal its phylogenetic relationships. A total of 12 species of Adiantum from this region and seven species from Java Island were collected and used in this study. Two cpDNA regions (rbcL and trnL-F) were chosen as markers and phylogenetic analyses were conducted using Neighbour-Joining (NJ) and Maximum Parsimony (MP) methods. The tree topologies reconstructed by NJ and MP from specimens used in this study and other species downloaded from GenBank are congruent in which trees are divided into five major clades. Adiantum species of Lesser Sunda Islands are not monophyletic and comprises three clades, i. e. Clade I composed of A. hispidulum group, Clade III composed of A. peruvianum group and Clade IV or A. caudatum group, each together with extra-Lesser Sunda samples. No sample from Lesser Sunda Islands examined is located in Clade II (A. tenerum group) and V (A. capillus-veneris group).

Abstract

NISHIDA, S. & VAN DER WERFF, H. Do cuticle characters support the recognition of Alseodaphne, Nothaphoebe and Dehaasia as distinct genera? Reinwardtia 14(1): 53 – 66. ? The Asian members of the Persea group are divided among the genera Alseodaphne, Apollonias, Dehaasia, Machilus, Nothaphoebe and Phoebe. A recent phylogenetic analysis has shown that Machilus and Phoebe are supported as monophyletic genera but evidence that the closely related genera Alseodaphne, Dehaasia and Nothaphoebe are monophyletic or not was equivocal. In this study we analyzed cuticle characters of 95 collections belonging to the Asian members except for Apollonias. We anticipated two possible outcomes. If the genera were not monophyletic, we expected that the groups based on cuticle characters would consist of species belonging to different genera. If the genera were monophyletic, we expected that the groups based on cuticle characters would consist of species belonging to the same genus. We found 16 groups based on cuticles. Of these, 12 consisted of species of a single genus (one group included a single species and thus a single genus).  The four mixed groups included mostly species of one genus with 1 or 2 species of a different genus. Our results support the recognition of Alseodaphne, Dehaasia, Machilus, Nothaphoebe and Phoebe as distinct genera.
