Note
|
This species is distinct in its hairy pods. They are transversely impressed and falsely septate between the seeds, but the transverse ridges are mostly hidden by the pubescence. Although reported to be sometimes showy in nature, on the herbarium sheet the flowers are seldom well preserved and are inconspicuous.
