Systematics of Arundinelleae and Andropogoneae subtribes Chionachninae, Dimeriinae and Germainiinae (Poaceae:Panicoideae) in Thailand

Abstract

This thesis has provided a comprehensive taxonomic account of tribe Arundinelleae, and subtribes Chionachninae, Dimeriinae and Germainiinae of the tribe Andropogoneae in Thailand. Complete floristic treatments of these taxa have been completed for the Flora of Thailand project. Keys to genera and species, species descriptions, synonyms, typifications, illustrations, distribution maps and Usts of specimens examined, are also presented. Fourteen species and three genera of tribe Arundinelleae, three species and two genera of subtribe Chionachninae, seven species of subtribe Dimeriinae, and twelve species and two genera of Germainiinae, were recorded in Thailand, of which Garnotia ciliata and Jansenella griffithiana were recorded for the first time for Thailand. Three endemic grasses, Arundinella kerrii, A. kokutensis and Dimeria kerrii were described as new species to science.
