The abaxial surface is covered in white pubescence.

The sessile, actinomorphic, perfect, complete, solitary flowers occur in the leaf axils. A stipular sheath subtends the flowers. The calyx has 4 fused, triangular sepals.  The corolla has 4 fused pubescent orange-yellow petals that form a short, pubescent tube.  There are 4 stamens that are fused to the perianth forming a hypanthium. The ovary is half inferior with 1 locule and many ovules.  The fruit is a capsule at maturity.
