ZAPATER, M. Alicia  y  LOZANO, Evangelina C.. Notas morfológicas sobre Bauhinia mollis y Bauhinia argentinensis: Fabaceae, Caesalpinioideae), nuevas citas para Argentina y Bolivia. Darwiniana [online]. 2012, vol.50, n.2, pp.339-354. ISSN 0011-6793.

The morphological variation in vegetative and reproductive structures of Bauhinia mollis (var. mollis and 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 geographic distribution 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.
