Diagnostic description

Distinguishing characters of C. woodii are: the densely villous-tomentose leaves and inflorescences which give shrubs a silver-green to grey-white hue, short, robust, upright panicles which bear numerous small flowers, and large, persistent stipules and bracts. Although similar, the fruits of C. woodii are broader and of thinner texture to those of C. sericea. From: Beaumont, AJ; Beckett, RP; Edwards, TJ; Stirton, CH. 1999. Revision of the genus Calpurnia (Sophoreae: Leguminosae). Bothalia 29(1): 5-23. [CC BY]

Habitat

C. woodii occurs on steep, dry slopes in loose, shaley soils undisturbed by cultivation or grazing and occurs at approximately 1 500 m above sea level.

Distribution

C. woodii has a very restricted distribution in KwaZulu-Natal , in the Underberg region and at South Downs, near Estcourt, Weenen County. The southeast-facing grassland slopes overlooking Wagendrift Dam and the Moor Park Nature Reserve near Estcourt, support a locally abundant population of this species.
