The leaves are rounded at the edges and at the keel, the tips are fairly flat and also rounded. Their surface is velvety. The outer wall of the epidermis contains a layer of crystal sand about 6 micrometers thick .

The one to three flowers are above bracts . There are five equal calyx lobes . Their petals are yellow, orange, or dirty reddish-yellow. The nectaries are wreath-like. The flowers open either in the afternoon or in the evening.
