Tropical Afbica. Uganda, without precise locality-, Daivel 



Described from a living plant sent by Mr. M. T. Dawe from 

 Uganda to Kew, where it flowered in June, 1913. 



This variety may prove to be specifically distinct from S. 

 nilotica, when living plants of both can be compared side by 

 side. Dried specimens of *S. nilotica differ in having longer 

 leaves, more gradually tapering at the apex, ami are very dis- 

 tinctly marked with rather crowded and very zig:?:ng transverse 

 bars, whili>t in the living plant of A^ar. oh-^cvra ih^ transverse 

 paler bars are indistinct and distant. See also a note under 5- 

 suhtilis.

 lanceolate, acute, with a stout green (not hardened) subulate

 the middle into a concave-channelled petiole very variable in
