 There seems lo be no iiiie of distinciion beiwccn these six forms, dilTerent as is 

 ihe appearance of some of them. They are all deliciously scenied, and among the 

 most valuabie lo cultivators. At one time I ihought. ihat ihc form of ihe lip and ihe 

 keels of ihe cresl , whicli are much lobed or toothed in D and E, might be laken as 

 s))ccific riiaiks : but I fear they ore inconstant and accidcnial. E was cultivaled in 

 1840. by ihe laie Mr. Barker, but I have not seen it since. Of C. no specimcns 

 are now in rny herbarium. 



Wild in Mexico and Guaicmala, very common.
