Abstract

Based on comparative floral morphology, and supported by molecular phylogenetic data, the foliose-rooted Thawatchaia trilobata gen. et sp. nov. (subfamily Podostemoideae) is described from northern Thailand. Similarities and dissimilarities in vegetative and reproductive characters between Thawatchaia and related foliose-rooted Asian genera are discussed and the consequence of their bearing on generic recognition is noted. The marginal meristem, which gives rise to the foliose root, was probably established at the base of a lineage leading to Thawatchaia, Hanseniella and Hydrobryum. A key to the Asian foliose-rooted genera is provided.
