Pseudoselago subglabra is an annual herb that grows to 80 cm. It has long, narrow leaves that are sometimes toothed. The plant grows in the southwestern Cape on damp, sandy mountain slopes.

This flat-topped flower cluster at a stem tip was seen in Bainskloof during October. The species is not threatened early in the twenty first century (Manning, 2007; www.redlist.sanbi.org).
