There are no examples from South Africa which admit of being unquestionably 
referred to Nusia congesta, R. Br., a species that in its typical form extends from 
the Shire Highlands to Abyssinia. The two varieties which occur in South Africa 
are readily distinguishable from each other and from the type, with which var. 
tomentosa agrees as to flowers and var. emarginata agrees as to leaves.
