Discussion
This species is so close morphologically to S. tessmannii that it might be considered, with nearly as much justification, a variety or subspecies of it. However, it appears that there are cumulatively sufficient distinctions to consider it a separate species, especially in light of the geographic disjunction of the two populations. The primary, most easily used, character for separating them is the presence or absence of pubescence on the gynoecium; S. oraria (pertaining to coastal regions) has larger stipules of different form, longer petioles and petiolules, larger bracts and buds, and a glabrous androecium and gynoecium.
