Monographs Details: Macrolobium savannarum R.S.Cowan
Authority: Maguire, Bassett & Wurdack, John J. 1957. The Botany of the Guiana Highland -- Part II. Mem. New York Bot. Gard. 9 (3): 235-392.
Family:Caesalpiniaceae
Discussion:

In the original description of this species, characters of the fruit were not supplied because material was not then available. Now a single fruiting collection (Maguire & Wurdack 34522) from the type locality has been received and they may be described as follows: Fruits glabrous, 6.5-8 cm long, 2.5-3 cm wide, oblong, carpophore about 4 mm long; seed laterally compressed, 15 mm long, 12 mm, wide, broadly oval, the testa tan, very thin-crustose.

As might have been expected, the fruits of M. savannarum are quite similar to those of its nearest relative, M. pendulum.
