Tropical Africa. Uganda; without precise locality, Dawel 

 Described from a living plant sent from Uganda by Mr. M, T. 

 Dawe to Kew. This and S. nilotica var. ohscvra were received 

 at the same time, without information, and are so very similar in 

 foliage that they were supposed to belong to one species and were 

 planted together in the same pot. When, however, they both 

 flowered at the same time on June 4th, 1913, it was at once seen 

 that they are certainly quite distinct in their flowers, and after 

 separating the two plants it was noted that they can be distin- 

 guished by the foliage of S. snbtllis being uniformly green on both 

 sides, with scarcely a trace of markings and having a shining 

 surface, whilst S~ nilotica var, ohscura has indistinct transverse 

 bars and a dull surface to its leaves.

 3^ ft. long, 1-2^ in. broad, strap-shaped, with the sides for a
