Opinions differ as to the claims of Odontoglosswim brevi- 
_ folium to be considered specifically distinct from 0. coro- 
~ narium, Lindl. They are regarded as varieties in Veitch’s 
_ excellent ‘‘ Manual ;”’ to which is added as another variety 
O. chiriquense, Reichb. f., but which latter, as Rolfe has 
pointed out (Orchid. Rev. vii. p. 49), differs far more from 
both than these do from one another. Referring to Mr. 
Rolfe, who kindly aids me in all my labours on Orchids for 
the Magazine, he informs me that O. brevifolium is well 
distinguished from O. coronarium by habit, by the closer 
pseudobulbs, larger (not smaller, as stated in Veitch’s 
* Manual’’) flowers, and shorter column. Theyfurther come 
from different countries, 0. coronarium from New Grenada, 
O. brevifolium from Peru, near Loxa, and differ in the first 
DECEMBER Ist, 1899.
