Abstract

A floristic survey was undertaken in mountains forest of West Sumbawa and some surrounding lower forests, an area of Indonesia receiving limited biological study. Three hundred sixteen species of Angiosperms and ferns were collected from this area in 2004 and 2005. The collection represents 101 families and 234 genera.

Abstract

GIRMANSYAH, DEDEN. 2009. A taxonomic study of Bali and Lombok Begonia(Begoniaceae). Reinwardtia 12(5): 419–434. A taxonomic study of Bali and Lombok Begonia was based on an investigation of morphological characters from 60 specimens in Herbarium Bogoriense.This study shows that there are 8 species that can be recognized: three species already in the genus (Begonia coriacea, B. longifolia, and B. tenuifolia) and five new (Begonia baliensis, B. lempuyangensis, B. pseudomuricata, B. multibracteata, and B. lombokensis).

Abstract

One hundred forty-five individual lianas were distributed on 2 East facing ridges on the second highest mountain on Java, Mt. Slamet (3418 m.), Central Java, Indonesia. Twenty one colonies were observed on small flat areas on ridges. The liana species observed include: Embelia pergamacea, Toddalia asiatica, Elaeagnus latifolia, Schefflera lucida, Vaccinium laurifolium and Lonicera javanica. Diameter of each liana was measured and liana density/flat area calculated. Floristic collecting was under- taken within the elevational gradient of liana distribution. Data suggest an ecotone transition from lower to upper mon- tane forest is observed between 2200 and 2300 m, though forest types are difficult to determine due to disturbance caused by fire at the upper elevations. Observing lianas at these unusuall high elevations with near pluvial rainfall, con- tradict established scientific theory concerning global distribution and abundance of lianas.

Begonia mekonggensis and Begonia watuwilensis belong to Begonia section Petermannia. Both species have characters which are very unusual amongst species in this section. Begonia mekonggensis is dioecious, and Begonia watuwilensis exhibits protandrous inflorescences with basal male flowers and several distal female flowers. Begonia aptera Blume subsp. hirtissima belongs to Begonia section Sphenanthera.
