[1] Yvonne Su and Richard Saunders, the botanists who first formally described the species, named it after its slightly uneven (obliqua, in Latin) leaf bases.

The young, light to dark brown branches are very densely hairy and have sparse lenticels.

The bases of the leaves are slightly uneven and pointed to broadly heart-shaped.

Its very densely hairy petioles are 6-15 by 1.5-2.5 millimeters with a broad groove on their upper side.

Its Inflorescences occur in clusters of 2–4 on branches, and are organized on indistinct peduncles.

The cream-colored to light brown, oval, outer petals are 1.5-2.5 by 1.5-2 millimeters with hairless upper and densely hairy lower surfaces.

The inner petals sometimes have a solitary, rod shaped, smooth, raised gland on their upper surface.
