Closely allied to S. anceps and has been distributed under the same — 
but besides differing in the subterete stem, more numerous and distant um ns 
and more hairy corolla-lobes, the lateral teeth of the corona-lobes are nearer be 
the top of the broad part of the lobe and also relatively to the top of the stamin 
column than they are in S. anceps.
