Adenocalymma marginatum
Adenocalymma marginatum (Cham.) DC.
Adenocalymma marginatum (Cham.) DC., a member of the Bignoniaceae family, is native to northeastern and southeastern Brazil, southern Brazil, Paraguay, Uruguay, and northern Argentina. It is distinguished by its leaflets with chartaceous texture and coriaceous margins, in contrast to similar species like A. bracteatum and A. paulistarum, which have membranous leaflets without such margins. It also features ovate, straight prophylls on axillary buds, differentiating it from A. bracteatum and A. paulistarum, which have triangular or curved prophylls, respectively. The species flowers throughout the year and fruits in March, May, and December.
