I have not seen the type of O. HofEman's species, which was 

 founded on a plant from Usula-Usiha in Massailand. Elliot describes, 

 I.e., this species as perennial, and includes under it a plant of his own 

 gathering from Fort Dauphin in Madagascar. The following Nos. 

 should be compared with this species : —

 perennial ; leaves radical, glaucescent, rosulate ; flowers whitish. In 

 hilly rather dry sunny places between Trombeta and Cambondo ; fl. 

 .and fr. Sept. 1854. No. 3632.

 year ; root branched, cylindrical, vertical, several-headed ; radical 

 leaves obovate, rosulate ; stems erect, much branched, sparingly and
