There is also considerable variation in the relative length of corona to anthers and in the size, shape, and indumentum of fruits.

Young shoots, pedicels, petiole and ovary stipitate-glandular and tomentose; upper layer of leaf indumentum spongy.

Indumentum stellate. Leaves large, opposite or whorled, petiolate.

Abaxial leaf indumentum initially yellow, later becoming deep red-brown, splitting.

indumentum especially of young plant parts and inflorescences reddish to yellowish.

abaxial surface indumentum thin, silvery-white, never developing a coppery sheen.

indumentum dark orange to pale beige-brown.

Key characters such as flower color and corolla indumentum show more variation than has traditionally been accepted.
