A PHENETIC STUDY OF THE CALAMUS FLABELLATUS COMPLEX (PALMAE) IN WEST MALESIA

SYAM, N., CHIKMAWATI, T. & RUSTIAMI, H. 2016. A phenetic study of the Calamus flabellatus complex (Palmae) in West Malesia. Reinwardtia 15(1): 27 - 41. — The number of species within the Calamus flabellatus  complex is still under controversy because the taxonomic status of the species is not yet clear. Morphological observations were conducted on 119 collections of Calamus in the Herbarium Bogoriense (BO) and specimen images from the  Singapore Herbarium (SING) and Kew Herbarium (K). The results showed that C. flabellatus complex (all species related to C. flabellatus)  in West Malesia  consisted of eight  species and two varieties, i.e. C. acuminatus, C. amplijugus, C. congestiflorus, C. corrugatus, C. flabellatus, C. hypertrichosus, C. javensis, and C. ruvidus. They can be distinguished using several characters, i.e. leaf sheath, knee, ocrea, leaves, inflorescence, shape of fruit, number scale of fruit and seed. Calamus flabellatus var. laevibus and C. flabellatus var. congestispinosus are two new proposed varieties. Phenetic analysis of C. flabellatus complex in West Malesia divided all species into two major clusters with similarity coefficient of 46%

Calamus Vitiensis (Arecaceae), a New Record of Rattan in Sumbawa Island, Indonesia

Calamus vitiensis, previously known to occur only in Papua New Guinea, Australia (Queensland), the Solomon Islands, Vanuatu, and Fiji is newly reported from Batudulang, a mountainous area in West Sumbawa, part of Lesser Sunda Islands.

ETNOBOTANI MASYARAKAT SAMAWA PULAU SUMBAWA

We have conducted an ethnobotany research in Batudulang Village of Batulanteh Subdistrict, Sumbawa Island, West Nusa Tenggara. This study was a direct observation method and data were collected by interview. This study aimed to determine the interaction of local community and its environment and to determine the local knowledge of useful plants. We recorded the people of Samawa utilized 147 plants, 39 were edible plants, 74 were medicinal including cosmetics plants, 12 were sources for building materials and handicrafts, and the rest of 22 were honeybee feed plants, firewood, and ritual plants. This study also revealed that the Samawa community has a local wisdom in the importance of sustainable used of the forest as a habitat for wild honeybees

INVENTARISASI PALEM DI HUTAN BODOGOL, TAMAN NASIONAL GUNUNG GEDE PANGRANGO

Palms inventory at Bodogol Forest, Mount Gede Pangrango National Park found 19 species of palms from nine genera. All those 19 species are two species of Arenga, three species of Calamus, two species of Caryota, five species of Daemonorops, one species of Korthalsia, one species of Nenga, two species of Pinanga, one species of Plectocomia and two species of Salacca. One species of Salacca is unidentified, further study is needed to clear up its taxonomy status. Identification key, synopsys of each species and its distribution at Bodogol forest are presented. Conservation status of each species presented

Keanekaragaman Palem Di Pulau Mendanau, Belitung

The study of palm in the Mendanau Island, Belitung was conducted in March 2017. There were 11 palm genera consisting of 14 species: Areca catechu, Calamus densiflorus, C. erinaceus, C. scipionum, Calamus sp., Caryota mitis, Daemonorops melanochaetes, Eleiodoxa conferta, Metroxylon sagu, Oncosperma tigillarium, Orania sylvicola, Pinanga malaiana, Plectocomia elongata, and Plectocomiopsis geminiflora. Based on the study of specimens deposited at Herbarium Bogoriense (BO), there were only four species recorded from Belitung Island, namely: Calamus erinaceus, C. scipionum, Eleiodoxa conferta, and Plectocomiopsis geminiflora. One species Calamus densiflorus is a new specimen collection for BO

THE TYPIFICATION OF GIGANTOCHLOA TALUH WIDJAJA & ASTUTI (POACEAE, BAMBUSOIDEAE)

The name of Gigantochloa taluh Widjaja & Astuti (Poaceae, Bambusoideae) was invalid because of failure to meet the requirements of the International Code of Nomenclature for algae, fungi, and plants, that there was no herbarium location of type specimens was mentioned. A typification was provided here to address this issue

Endemic Bamboo (Poaceae, Bambusoideae) of the Lesser Sunda Islands

More than 50 species of bamboo were known from the Lesser Sunda Islands (LSI), including several endemic species. Endemic species are often highly specialized, found in limited geographical areas, and vulnerable to extinction if their habitat is destroyed. This study aimed to provide an account of endemic bamboo species on the LSI. Fieldwork involved collecting samples of bamboo in the LSI. Herbarium specimens of bamboo deposited in the Herbarium Bogoriense (BO), collected from the LSI were examined, and endemic LSI species were recorded. The conservation status followed the International Union for Conservation of Nature (IUCN) red list categories and criteria. The conservation status of unassessed species was evaluated using IUCN red list categories and criteria. A spatial analysis was also conducted. Data were analyzed and presented descriptively. There are 10 endemic bamboo species in the LSI, namely Bambusa ooh Widjaja & Astuti from Bali (conservation status: endangered), Chloothamnus reholttumianus (Soenarko) Widjaja from Sumba (vulnerable), C. schmutzii (S.Dransf.) Widjaja from Sumbawa and Flores (near threatened), Dinochloa kostermansiana S.Dransf. from Sumba and Flores (near threatened), D. sepang Widjaja & Astuti from Bali (vulnerable), Fimbribambusa rifaiana Widjaja from Alor (near threatened), Gigantochloa aya Widjaja & Astuti from Bali (vulnerable), G. baliana Widjaja & Astuti from Bali (vulnerable), G. taluh Widjaja & Astuti from Bali (vulnerable), and Schizostachyum purpureum Damayanto & Widjaja from Sumba (data deficient). They can be found at an altitude of 20–1700 m in various habitats, including forests, bamboo forests, villages, botanical gardens, along a road, slopes, valleys, riverbanks, and around a lake
