This little plant was sent in April, 1840, by Mr. Parkinson, 
English Consul in Mexico, to the “ princely” Woburn collection, © 
as collected by M. Galeotti in Mexico. Sir Wiliam Hooker cor- 
rectly stated it to be ‘‘ quite unlike any other species of the genus 
with which I am acquainted.” ‘he drawing, published in 1841, 
was prepared by Mr. W. Fitch, and may candidly be recommended 
to many now-a-days so-called artists. Itis a chaste and honest 
representation of the plant, as it was, and the few small faults 
(hairs on the back of column, not enough hairs on the callus of 
the lip, and the connate pollinia, in fig. 6) may not have been 
his, but Mr. Swan’s, who engraved the plate. My wild speci- 
mens are all Mexican: Xalapa, Leibold! Mhrenberg!—513
