Abstract
-
The main purpose of this study is to prepare a taxonomic account of the tribe Andropogoneae (Gramineae) for the "Flora of Thailand". Three major subtribes Andropogoninae, Anthistiriinae and Saccharinae, presenting difficulties in the classification, were selected for the present study. Specimens of the studied taxa were all carefully disected and studied, and both macro- and micro- morphological, geographical and ecological data were utilized for drawing the taxonomic conclusion. Fully described taxonomic accounts have been prepared for all the taxa that I recognized as valid, and selected species were illustrated by line drawings and macroscopic photographs so that the vegetative and floral parts are better shown. Within the whole tribe Andropogoneae, the study covers only a relatively small regional part. Therefore, no attempt has been made to discuss the relationships among the genera and subtribes. Being a floristic study, the effort of taxonomic research was focussed on the specific and infraspecific taxonomic levels and a large number of previously undetermined Thai specimens of the tribe were identified. As a result, a total of 73 species in 19 genera are described. Keys to the Tai species are prepared and their nomenclatural problems have been solved. Four specimens: Adisai 995 (BK); Kerr 10133 (BK); Koyama et al. 15522 (NY); and Smitinand 8423 (BKF), are being studied separately as they may represent new taxa. The taxonomic study is based on the material collected from Thailand from the following herbaria: AAU, BK, BKF, GH, K, NY, UC, and US.
