Discussion:It is interesting that this species is both geographically and morphologically intermediate between its near-relatives S. chimantaensis and S. neblinaensis. It has similar flowers but its fruits are more like those of S. chimantaensis, except that they are pubescent on the seed-bearing portion as in S. neblinaensis; the leaflets are quite similar to those of S. chimantaensis but on a longer rachis as in its other relative. The new species differs from S. chimanatensis in its entire sepals and from S. neblinaensis in the shape and pubescence of the fruit.
