The fan-like leaf blades are each divided into leaflets which are deeply dissected into narrow segments, the whole blade borne on a long petiole.

A solitary flower is borne on a long, upright stem.

It has five yellow petals, the lower three veined with purple-brown and the upper two stained purple-brown on the outer surfaces.
