 uted throughout America and perhaps elsewhere. 



10. OREOMYRRHIS Endl. Gen. Plant. 787. 1839. 



A genus of wide distribution, represented within our range by the 

 single polymorphic Andean species O. andicola Endl. (cited by 

 Hemsley as O. andifia). The two new species doubtfully referred 

 by Hemsley to this genus he has since transferred to his new genus 

 Neogoezia. 



II. NEOGOEZIA Hemsley, Kew Bull. 354. 1894. 



Mr. Hemsley founded this genus upon two species that he had ten- 

 tatively described under Oreomyrrhis^ viz., N. gracilipes and N. 

 planipetala^ and added a new one, A^. minor. The genus is restricted 

 to Mexico, so far as known, and there are indications of a fourth 

 species not yet described.
