Bentiani himself (Mart. Fl. Brasil, Joc. cé#.) says that S. florc- 
bundum = A. pulcherrima Willd. and that it is very closely allied 
to Piptadenia (or Stryphnodendron) guyanensis; but the two 
species are kept separate and Bentham makes a note in which he 
quotes Schomburgk no. 799 as S. floribundum. 
The originals of S. guyanense in Herb. Paris have the leaflets 
very variable in size, but none of them has such small ones as our 
plant. Therefore Bentham was entitled to keep the two species 
separate; butif S. floribundum (= A. pulcherrima) is a distinct 
species, it must bear the prior name S. pulcherrimum. 
DIMORPHANDRA BIRETUSA Tul. Arch. Mus. Paris 4: 184 
Brasilia trop. (Blanchet no. 3092) in Herb. N. Y. Bot. Gard. 
If we compare Blanchet no. 3092, which is the type of D. 
btretusa Tul., and Gardner no. 1944, which is the type of D. 
Gardnerana Tul., we find them specifically different. D. Gard- 
nerana has smaller and thicker leaflets, with recurved margins, 
and shorter petiolules than in our species; they are always less 
than 1 mm. long. Besides, the anatomy of the leaflet is different, 
the epiderm of D. Gardnerana being characteristically sclerose. 
The inflorescence axes of D. Gardnerana also seem a little thicker.
