The locality, West Africa, given by Lindau is presumed an error.

It has been doubted whether this is specifically distinct from S. Vogelii. The 

 habit of the almost gnarled slender branches is different, the posticous calyx-segment 

 is twice as broad at least, and the habitat is remote. 



7. S. scissisepalus, C. B. Clarke. Bracteoles J by i in., lanceo-

 as S. Holstii.

 The nodose crooked branches and inflorescence are altogether like those of S. 



Holstii ; the calyx is very minutely pubescent, as also the rhachis of the spike. 



There is only one good flower; but the bifid tip to the posticous calyx-segment is 



remarkable, and indicates an approximation to Crossandra.
