Discussion:la. Burdachia sphaerocarpa Adr. Jussieu var sphaerocarpa Burdachia atractoides Niedenzu, Arb. Bot. Inst. Ak. Braunsberg 5: 59. 1914. Syntypes. Amazonas, Brazil, Glaziou 13592; Manaus, Schwacke III 266 (RB!). The collection from Rio l├žana, Froes 21413, has unusually wide leaves and 2-6 flowers in each cincinnus instead of the 1-2 found in most plants of Burdachia sphaerocarpa. Perhaps it deserves recognition as a variety, but that would best await further collection, especially of material with flowers.
