 would appear from the characters given not to be separable from Synantherias. 

 It was founded on a Canara plant collected by Hohenacker, of which I have 

 seen no specimen ; and is described and figured as having a few gibbous neuters, 

 and a slender subulate appendage shorter than the spathe. In other respects it 

 agrees with S. sylvatica.
