PLANTS COLLECTED IN NY AS ALAND 



475 



North Nyasa District: Nyika Plateau, occasional in montane forest secondary 

 growths and in grassland shrubberies, shrub 1 m. high, leaves greyish-green, 

 flowers purple, 2400 m., Aug. 18, 1946, 173 19 . New to Nyasaland; the var. ex- 

 tending northward to Kenya and Uganda. 



Levyns in her revision of Stoebe (I.e.) does not mention the var. densiflora, 

 and recognises no varieties of 5. kilimandscbarica. To me, however, var. densi- 

 flora appears worth distinction. Plants from Kilimanjaro and other peaks in north- 

 eastern Tanganyika have short incurved and rather appressed foliage on the ma- 

 ture shoots, and these represent typical S. kilimandscbarica. From elsewhere — 

 southern Tanganyika, Kenya, Uganda and now Nyasaland — the foliage is longer, 

 mostly spreading and not incurved. I have not seen the type of var. densiflora 

 (Goetze 1198 from the Kinga Mountains in southwestern Tanganyika), but the de- 

 scription does not leave room for doubt, and there are in the Kew Herbarium gath- 

 erings from southwestern Tanganyika, where typical 5". kilimandscbarica does 

 not seem to occur. From the description, S. elgonensis Mattf. Notizbl. Bot. Gart. 

 Berlin 8: 236 (1922) is a synonym of var. densiflora.
