Discussion:
The apiculate anther-connective of this species and its near relatives clearly connect them evolutionarily with similar species, such as those of the S. cardiosperma complex, which have proportionately a much longer style and shorter ovary. The new species described above is even nearer to S. santanderensis and S. apiculata; the former has differently shaped leaflets and a different type of pubescence, and the latter has smaller leaflets, and shorter pedicels and anthers.
