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

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. 
fre is only one good flower; but the bifid tip to the posticous calyx-segment 1s 
“emarkable, and indicates an approximation to Crossandra.
