Calpurnia woodii, commonly the woolly calpurnia, is a compact, branched shrub that reaches 2 m in height. Young stems are whitish from a hairy covering, the plant generally hairy.

The distribution is confined to an area in northern KwaZulu-Natal at elevations around 1500 m. The species is considered vulnerable due to its very restricted distribution and overgrazing of and too frequent fires in part of this area (Coates Palgrave, 2002; Beaumont, et al, Bothalia 29,1: 5-23 (1999); www.redlist.sanbi.org).
