Described by permission of Dr. H. H. Rusby, who long ago recog- 

 nized the novelty of the plant but through pressure of professional 

 duties has been unable to study it in detail and give it published 

 record. The species is dedicated to his associate Mr. Roy W. Squires, 

 who accompanied him on the arduous trip of exploration during which 

 this plant, together with many others, Avas discovered.
