This genus contains, besides seven new species, a great number of 

 those which have usually been placed under Hyraenophyllum ; and 

 the author arranges them under three subdivisions, which he names 

 Stellata, Pilosa and Glabra : he speaks of the great difficulty of ac- 

 complishing a subdivision satisfactory to himself, and acknowledges 

 the probability of better diagnostics being hereafter found : the names 

 of the divisions now employed sufficiently show the characters he has 

 selected.
