Otholobium lanceolatum is a small subshrub of up to 20 cm (7.9 in) high, that is assigned to the Pea family. It has up to 7 horizontal stems with raised tips, few hairless, alternately set leaves with only one leaflet and clusters of 15-27 white, pea-like flowers with a purple tip near the top of the short, seasonal shoots. It is endemic to one site near Caledon, South Africa. Flowers only appear in November and December within one year after a fire destroyed the vegetation.
