摘要
Three new species of Pseudo/Hun/HuDugand (Malvaceae, Bombacoideae) are described and illustrated based on material from Brazil. Pseudobombax minimum. Carv.-Sobr. & L. P. Queiroz is not clearly related to any species of Pseudobombox from central-eastern Brazil. However. P. minimum may he promptly recognized by its extremely reduced flowers (to 6 cm long) and fruits (to 5.5 cm long), the smallest recorded for Psendobombax to dale, in combination with the glabrous androecium and the presence of phalanges. The other two new species. P. calcicola Carv.-Sobr. & L. P. Queiroz and P. parvifolium. Cary.-Sobr. & L. P. Queiroz, seem to he related to P. grandiflorum (Cav.) A. Bobyns based on the number of leaflets and the absence of phalanges in the androecium, but differ due to the absence of intersecondary veins, the larger ovary, and the fruits angled, but not winged.
