Morphological notes on Bauhinia mollis and Bauhinia argentinensis (Fabaceae, Caesalpinioideae), new records for Argentina and Bolivia

Abstract

The morphological variation in vegetative and reproductive structures of Bauhinia mollis (var. mollisand var. notophila) and B. argentinensis (var. argentinensis and var. megasiphon) were studied. This detailed morphological study enabled us to correctly identify herbarium specimens and expand the geographicdistribution of the taxa. New records of B. mollis var. mollis for Argentina and B. argentinensis var. argentinensis and B. argentinensis var. megasiphon for Bolivia, the latter considered endemic to Argentina, are here confirmed. Lectotypes were designated for Bauhinia mollis, B. mollis var guaranitica and B. appendiculata
