Notes
Vernacular names as recorded in specimen data include: “mologa” (setstwana); “cassaca” (Tete area); “kanunkila” (Tok.).The flowers remain in bud all through the dry season and open with the first rains (Mrs Lugard).The dried flower buds when crushed smell strongly of certain Labiatae (e.g. Thymus, Salvia spp.).
