CRISTATO-GRACILE Могу (Woll.) 
Mr. |, Moly. 5. Devon. 1868. 
1ft. Sin. 
‚Syn. PERCRISTATUM Могу. 
So thoroughly crested in ай their parts are the true forms of 
ristato-gracile, that the name percristatum might with propriety be 
given to them. The original form was found in 1862 in S. Devon 
by Mr. Grey. Shortly afterwards Mr. Jackson found his in 
М. Devon. It is believed that Mr. Wollaston, Mr. Wills, and Mr. 
Charles Cowper are the only other discoverers of the true form of 
this variety. Mr. Elworthy's and Mr. Padley's crested forms, 
called by this name, lack the percristate character which is now 
considered as the only claim to this name. Mr. Moly's form is 
now generally admitted to be the finest and most characteristic of 
the class—next probably in excellence come two of Mr. Wills's, 
the pale-complexioned one found in Dorset, in 1872, and the 
Sidbury one found in 1874, and Mr. Grey's well-known dark green 
form. Мг. Moly has two forms. |
