The Genus Koilodepas Hassk. (Euphorbiaceae) in Malesia

The Malesian genus Koilodepas Hassk. has been revised based on the morphological and anatomical character using available herbarium collection in Herbarium Bogoriense and loan specimens from Kew Herbarium and Leiden Rijksherbarium. The present study is based on the observation of 176 specimens. Eight species has been recognized, namely K. bantamense, K. cordifolium, K. frutescns, K. homalifolium, K. laevigatum, K. longifolium, K. pectinatum, and two varieties within K. brevipes. The highest number of species is found in Borneo (5 species), three of them are found endemically in Borneo, K. cordisepalum endemically in Aceh, and K. homalifolium endemically in Papua New Guinea. A phylogenetic analysis of the genus, with Cephalomappa as outgroup, show that the species within the genus Koilodepas isin one group, starting with K. brevipes as a primitive one and K. bantamense occupies in an advance position.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeyword: Koilodepas Hassk., Malesia, outgroup, phylogenetic analysis, outgroup

Vegetative character and reproductive at Argostemma from Mount Gede-Pangrango, Mount Halimun, and Mount Salak have been used for the identification of 101 herbarium specimens from Herbarium Bogoriense and new specimens from field. Identifying of herbarium specimens based morphology character on Argostemma hybrid group by previous author still identified as Argostemma montanum. Ovary at Argostemma consist of 2-3 celled, ovary 2 celled is found at A. montanum and A. borragineum, while the ovary of A. uniflorum account of3 celled. Amount of flower do not range from 3-6, but between 1-8. Study on Argostemma morphology also can be concluded that in Mount Gede-Pangrango, Mount Halimun, and Mount Salak there are 3 Argostemma species, that is A. montanum Blume ex DC, A. borragineum Blume ex DC, and A. uniflorum Blume ex DC. Spreading of Argostemma vertically in Mount Gede-Pangrango, Mount Halimun, and Mount Salak range from 560-2,600 m above sea level. with spreading center 1,000-2,000 m above sea level.© 2005 Jurusan Biologi FMIPA UNS SurakartaKey words: Argostemma, morphological characteristics, herbarium specimens, Mount Gede-Pangrango, Mount Halimun, Mount Salak.

Taksonomic study on Micromelum Blume (Rutaceae) in Indonesia

Taxonomic study on Micromelum Blume was conducted at Herbarium Bogoriense (BO) and Kew Herbarium (K) and using 84 collections number of herbarium specimen. This research used descriptive method based on morphological characters. Terminology by Stearn (1983) was used, whereas the revision method as described by Rifai (1976) and Vogel (1987) were used. Based on this study were produced two species only of Micromelum respectively which occurred in Indonesia. They were Micromelum diversifolium Miq. and M. minutum (Forst. f.)Wight. & Arn. M. diversifolium had two varieties, i.e. M. diversifolium Miq. var. diversifolium and M. diversifolium Miq. var. cuneata Miq. Whereas M. minutum had three varieties, i.e. M. minutum (Forst. f.) Wight. & Arn. var. minutum, M. minutum (Forst. f.) Wight & Arn. var. tomentosum Tan. and M. minutum (Forst. f.) Wight & Arn. var. villosum Tan. New record specimen collections of M. diversifolium from Biak Island (Papua) was reported also.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: Micromelum spp., taxonomy, Rutaceae, Indonesia.

R E V I E W: Ecological distribution of Dipterocarpaceae species in Indonesia

Dipterocarpaceae is one of the biggest family with >500 species in the world, and most of dipterocarps population aregrown in Indonesia which have high economical value of wood. One of the most important value from dipterocarps species is high on endemicities; there are up to 128 species (53.78%) from 238 dipterocarps species in Indonesia. Distribution of dipterocarps species would be affected by some factors especially edaphic, climate, and altitude. In Indonesia the dipterocarps species distribution could be shown from islands groups, number of species and forest types. Based on the observation of herbarium collection in Herbarium Bogoriense the distribution of the most dipterocarps species was in the altitude of 0-500 m and 500-1000 m on the dipterocarps forest type. Kalimantan and Sumatra were the two bigger islands with have the dipterocarps species distributed relatively high on population and species.© 2004 Jurusan Biologi FMIPA UNS SurakartaKeywords: Dipterocarpaceae, ecological distribution, altitude, Indonesia.

Diversity of Selaginella across altitudinal gradient of the tropical region

Setyawan AD, Supriatna J, Darnaedi D, Rokhmatuloh, Sutarno, Sugiyarto. 2016. Diversity of Selaginella across altitudinal gradient of the tropical region. Biodiversitas 17: 384-400. Selaginella prefers moist environment for its growth and requires water for fertilization; therefore it is often found flourish in plateau and hilly mountains with high rainfall. The aim of this research was to know species diversity of Selaginella along altitudinal gradient in the southern part of Java, Indonesia. The research was conducted between July 2007 and January 2014across the altitudinal region of Java, Indonesia, which includes the districts of Wonosobo, Purworejo, Kebumen, Banjarnegara and its border areas, with altitudes between 0 and 2500 m. asl. The research found 12 selaginellas species, 10 species collected from field research, namely: S. aristata, S. ciliaris, S. intermedia, S. involvens, S. opaca, S. ornata, S. plana, S. repanda, S. remotifolia, and S. uncinata; and two species only known from herbarium collection of Herbarium Bogoriense (BO), namely S. singalanensis and S. willdenowii. This research was the first publication of the Selaginella flora along altitudinal gradient from the coastal area to the high mountains of Central Java, Indonesia.

THE GENUS TEIJSMANNIODENDRON KOORDERS (VERBENACEAE)

1. The present notes on Teijsmanniodendron are based on a study of the specimens from Herbarium Bogoriense and the Herbarium of the Singapore Botanic Garden. 2. The taxonomic value of the principal characters and their variation are discussed. Each of the species recognized is annotated. 3. A delimitation and subdivision of the genus in two sections, 'Plurifoliolatae Kosterm.' and 'Unifoliolatae Kosterm.,' is proposed. 4. A key to the 12 species and 1 variety distinguished, is included. 5. One new species is provisionally described (but not named), and one new variety, Teijsmanniodendron pteropodum var. auriculatum Kosterm., is published. 6. The following new combinations are made: Teijsmanniodendron coriaceum B. Clarke) Kosterm., T. hollrungii (Warb.) Kosterm., T. holophyllum (Bak.) Kosterm., T.novoguineense (Kan. & Hatus.) Kosterm., T. sarawakanum (H. H. W. Pears.)Kosterm., T. smilacifolium (H. H. W. Pears.) Kosterm., and T. subspieatum (Hallier f.) Kosterm. 7.. The genus Xerocarpa H. 3. Lam (non Spach) is rejected; its only species,X. avicenniaefoliola H. J. Lam, is referred to Teijsmanniodendron ahernianum (Merr.)Bakh. In addition, the following reductions are made: Teijsmanniodendron monophyllum Kurata = T. hollrungii (Warb.) Kosterm.; Vitex bankae H. J. Lam = T.ahernianum (Merr.) Bakh., V. bogoriensis H. J. Lam = T. ahernianum (Merr.) Bakh.;V. koordersii H. J. Lam t= T. pteropodum (Miq.) Bakh.; V. tetragona Hallier f. =T. sarawakanum (H. H. W. Pears.) Kosterm.; V. venosa H. J. Lam = T. coriaceum (C. B. Clarke) Kosterm. Possible identity of T. longifolium (Merr.) Merr. and T.bogoriense is suggested: the identity of T. simplicifolium Merr. and T. smilacifolium(H. H-, W. Pears.) Kosterm. is indicated as probable. 8. Vitex subspicata Hallier f. and V. holophylla Bak., included by Lam in Vitae hollrungii Warb., are reinstated as distinct species of Teijsmanniodendron.
