N. B. This genus has been inserted inBixineae, p. 297. vol. 1. 

 of this work, but since that part of the work has been printed 

 the genus has been discovered to belong to Homalinece. We 

 have therefore given a fresh character both of the genus and 

 species.

 parted, spreading, with the segments somewhat imbricate in 

 aestivation. Stamens indefinite, many sterile.
