Has the habit of the Natal S. longifolia. Hook. f„ but is markedly different in its 

 trilobed lip. From S. fimh-iala, Lindl., it differs in the shape of the leaves, and in 

 various other details. Cultivated specimens introduced by Mr. Buchanan flowered in 

 the Edinburgh Botanic Garden, in 1881.
