The position it should occupy within the genus, however, is still
difficult to determine. The shape of the leaves and particularly the
indument suggest species of Plectostemma section Cieca, but the
operculum is not plicate and the petioles are glandless. The angular,
stipitate fruit suggests P. gracilis, also of Plectostemma, but the
seeds are quite different. Probably Masters' placing of it in Granadilla
is the best disposition possible, though here it clearly represents
a monotypic section. The corona is definitely 2-ranked, and there
is no vestige of a third row of filaments or of tubercles on the smooth
inside of the calyx tube. The operculum is entire at the margin,
without crenations or undulations of any kind.
