  • Discussion

    The principal difference separating this species from S. laurifolia is the sparsely strigulose gynoecium in contrast to the sericeous one of S. laurifolia. In addition, there is a difference in the shape of the leaflets of which there are fewer pairs in S. fraterna; there is also an obvious difference in the form of the petal. In most other respects, however, there is considerable similarity, hence the specific epithet.
