Authority: Maguire, Bassett. 1965. The Botany of the Guayana Highland. Mem. New York Bot. Gard. 12 (3): 1-285.
Discussion:Cunninghamia sarmentosa (Aubl.) Willd. Sp. PI. 1: 651. 1798.
I have interpreted this species in a restricted sense. The photo of the type shows leaves revolute, conspicuously rugose both sides with prominently sulcate nerves above, oblong-obovate to oblong leaf-blades obtuse at the apex, and an inflorescence 8-10 cm long, the lowest of the 4-5 flower-clusters on short axes 8 mm long. A specimen from British Guiana, Sandwith 1163, matches the photo of the type.
A large number of specimens have been identified as this species, but an examination of all this material has resulted in the segregation of a number of taxa, obviously related to M . sarmentosa, but differing from it in sufficient characters of specific value to justify a separation. Within 31. sarmentosa is found a range of variation, expressed in the following key to varieties and forms.
