Abstract

SADILI, A., KARTAWINATA, K., KARTONEGORO, A., SOEDJITO, H. & SUMADIJAYA, A. 2009. Structure and composition of subalpine summit habitats on Mt. Gede-Pangrango complex, Cibodas Biosphere Reserve, West Java, Indonesia. Reinwardtia 12 (5): 391–404. We undertook a phytosociological analysis of the subalpine herbaceous and shrubby vegetation at the Mandalawangi and Suryakencana meadows and the scrub at the Crater Side at the tops of Mt. Gede and Mt. Pangrango in the Cibodas Biosphere Reserve. We recorded 30 species of 18 families of saplings, shrubs, seedlings and herbs in 78 quadrats with a total area of 7,800 m2. Anaphalis javanica, a woody tall herb and long-lived pioneer was the dominant species in the sapling and shrub stratum, while Isachne pangerangensis, Tripogon exiguus and Carex verticillata were prevalent in the seedling and herb stratum at Mandalawangi and Suryakencana. Stunted shrub is Vaccinium varingaeifolium, dominant in the Crater Side scrub. Based on the importance values, the Mandalawangi meadow may be designated as the Anaphalis javanica-Isachne pangerangensis community type, the Suryakencana meadow as Anaphalis javanica-Tripogon exiguus community type and the Crater Side scrub as Vaccinium varingiaefolium-Seliguea feei community type. The similarity indices between Mandalawangi and Suryakencana community types were very high (>75 %) while those between the Crater Side and Mandalawangi and the Crater Side and Suryakencana were very low (

SUMADIJAYA, A. & VELDKAMP, J.F. 2009. Notes on Bothriochloa Kuntze (Gramineae: Andropogoneae) in Malesia. Reinwardtia 12(5): 415 – 417. — The note is preliminary part for studies of Bothriochloa Kuntze in Malesia. Special caution should be given to Bothriochloa intermedia (R. Br.) A. Camus, now B. bladhii (Retz.) S.T. Blake, because of the variation, synonyms, and natural hybridization to generic level.

Abstract

Thirty two species of non-bambusoid grasses from 28 genera were recorded for the Raja Ampat Archipelago, Papua Barat Province, Indonesia, mostly from secondary forest. The result was compiled from Widya Nusantara Expedition (EWIN), Takeuchi (2003), and Van Royen (1960). This is a first attempt to record non-bambusoid grasses for a remote archipelago in Indonesia.

Abstract

The Herbarium Bogoriense (BO), an integrated part of the Botanical Division, Research Center for Biology, Indonesian Institute of Sciences, receives plant specimens to be identified on a daily basis. In a six year period from 2005 to 2010, data were extracted from thousand of identification requests by hundreds of clients. Patterns were observed based on variables such as time, plant groups, client expertises, and taxonomic level. Outputs from these analysis are being expected to become one of the pillar to build a unifying scheme for botanical research at the Herbarium Bogoriense by focusing on human resources development to deal with biodiversity issues about frequently encountered taxa.

YUZAMMI, ERLINAWATI, I., ASIH, N. P. S., DAMAYANTO, I. P. G. P., SUMADIJAYA, A., SULISTYANING-SIH, L. D., ARDIYANI, M., RUSTIAMI, H., WITONO, J. R., KEIM, A. P. & RAYHANNISA. 2025. Synthesis of Bucephalandra Schott (Araceae: Schismatoglottideae) studies in Kalimantan, Indonesia: checklist, key, and updated distribution maps. Reinwardtia 24(2): 185‒198. — Bucephalandra, a member of the Araceae family, is an endemic rheophyte genus of Borneo. The majority (26 out of the 32 species) of this genus, are found in Indonesian Borneo (Kalimantan). Bucephalandra oblanceolata (M.Hotta) S.Y.Wong & P.C.Boyce, previously known from Brunei and Sarawak, has been identified in Kalimantan. This study presents a comprehensive overview of Bucephalandra in Kali-mantan, accompanied by a detailed map and an identification key.
