Described by permission of Dr. H. H. Rusby, who long ago recos- 
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, was discovered.
