P., ARINASA, I. B. K. 2004. New species of bamboos (Poaceae-Bambusoideae) from Bali. Reinwardtia 12(2):199 - 204. Five new species of bamboos from Bali are described: Bambusa ooh, Dinochloa sepang, Gigantochloa aya, Gigantochloa baliana and Gigantochloa taluh in the context of a proposal field guide to Balinese bamboos. Description including the distribution and the vernacular names are provided. Keywords: Bamboo, Bali, Bambusa ooh, Dinochloa sepang, Gigantochloa aya, Gigantochloa baliana, Gigantochloa taluh. ABSTRAK WIDJAJA, E.A., ASTUTI, I. P, ARINASA, I. B. K. 2004. Jenis baru bambu di Bali. Reinwardtia 12(2): 199 - 204. Lima jenis baru bambu dari Bali diusulkan yaitu Bambusa ooh, Dinochloa sepang, Gigantochloa aya, Gigantochloa baliana, Gigantochloa taluh dalam mempersiapkan panduan lapangan Bambu di Bali. Pertelaan termasuk persebaran dan nama daerahnya juga dikemukakan. Kata kunci: Bambu, Bali, Bambusa ooh, Dinochloa sepang, Gigantochloa aya, Gigantochloa baliana, Gigantochloa taluh. With the new species Dinochloa sepang, Dinochloa is a new generic record for Bali. Although the Balinese flora is closely related to Javanese one, many species appear to have a very local distribution. Gigantochloa appears to be more diverse in Bali then in Java, and some species appear to be common and have a high usage in Bali. The new species were found in the Bangli District where bamboo community gardens occurs. INTRODUCTION Of the bamboos occurring in Indonesia, 37 species so far have been discovered in Bali, nine of which could not be identified (Widjaja, Astuti, Arinasa & Sumantera, 2004), as without flowering material identification of bamboos is usually impossible. No overall review of Balinese bamboos has been published, although several species have been mentioned in various reports (Arinasa & Widjaja 2003). We aim to prepare a general field guide for which the present publications is a precursor. Recently, four species of the unknown taxa have come into flower making identification possible. One species of Bambusa not previously collected and still only known in the sterile state appears to be sufficiently distinct to allow description. Flowering material of the four remaining species hopefully will become available soon so that the field guide can be completed. Bambusa ooh Widjaja & Astuti sp.nov. – Fig.1 & 2.
