ОЕ WELWITSCH'S ANGOLAN HERBARIUM. 263 
mentis lanceolatis acutis per totam latitudinem laxe nervatis. Stamina perianthio 
paulo breviora, antheris linearibus 4 lin. longis. Ovarium basi inferum, loculis 4-7- 
ovulatis. Capsula cernua. Ми а, in collinis petrosis, alt. 3800-5500 pedum. 
Intermediate between JF. nutans and W. Mackenzii of Zambesi-land. They may likely 
prove all three, as Dr. Welwitsch suggested to me, varieties of a single species.
