(Vol.10, 2007-12) Phaseolus Texensis (Leguminosae: Phaseolinae): A New Species from the Edwards Plateau of Central Texas

Phaseolus texensis is a new species known only from rocky canyons of the eastern and southern Edwards Plateau of central Texas. Morphological examination and field observations, in conjunction with current molecular phylogenetic analyses based on nuclear ribosomal and chloroplast DNA sequences and a discrete and limited geographical range, support the taxonomic recognition of this species, which is accordingly described and illustrated here.Billie L.
