is a distinct species easily distinguished from all others in the genus by the dense, velvety indumentum of the stems and lower leaf surfaces. It is also distinctive in its side shoots with more numerous leaves than other members of the genus (6-8 versus 2-5), which are almost all elliptic (versus variously ovate to broadly ovate).
