The section Myanthum was established by Lindley (Fol. 
Orchid., p. 11), for the reception of a few species of 
Odontoglossum, in which the lateral sepals, instead of being 
widely spreading, are more nearly parallel and deflexed 
more or less under the lip, and the lip is sessile, or nearly 
so; the lateral sepals should further be manifestly clawed, 
but this is not the case in the plant here figured. 
O. retusum was discovered by Hartweg in 1841, on 
rocks in the mountains of Saraguru, near Loxa, in Ecuador 
(not Peru, as stated by Lindley) in no doubt a temperate 
climate, the Loxa valley being 6-8000 ft. above the sea. 
It was imported into this country upwards of fifteen years 
ago, as there are specimens in the Kew Herbarium received 
from Messrs. Veitch in 1884. There are also others re- 
ceived from Messrs. Sander & Co. in 1891, and in the 
same year from Mr. Linden’s establishment (L’Hortic. 
Internationale) in Brussels. The specimen figured was 
communicated by E. H. Woodall, Esq., of St. Nicholas 
House, Scarborough, in April, 1897.
