Discussion
The relationship of this species to S. polyphylla is obvious, the most conspicuous difference being the different aspect of the lower surface of the leaflets in S. schomburgkii. The buff-colored lower surface, like that of S. duckei, S. gigantea, and S. jenmanii, is caused by the presence of a dense covering of microscopic peltate hairs. Var. guayanensis is distinguished from the other two varieties by its densely pubescent gynoecium and its depressed-globose buds; var. rigida is distinguished from the typical variety by its rigid-coriaceous leaves and larger verruculous buds, but the two are similar in the form of the buds and in the lack of gynoecial pubescence.
