two triangular blunt serrulate wings, whitish, as is the column, 
but with purplish dots. The anther is oblong-acute, velvety, 
white, with small triangular valves of the locelli. Pollinia pyri- 
form, retuse, channelled on the inferior side on a broad tri- 
angular caudicula, now rounded, now apiculate at the base, 
bearing a brown small ligulate glandula. We have not seen such 
a narrow caudicula as is represented by Mr. Fitch.

The species of the genus T'richocentrum prefer growing on 
blocks of wood to any other method of growth that they have 
been subjected to at Hillfield. They should never be allowed to 
become dry, should be kept near the light, and shaded from the 
mid-day sun. They do well in the Mexican house. So treated 
the species flower freely, and the plants appear very healthy and 
strong. This plant I received from the rich collection of Mons. 
Linden, of Brussels.—W. W. 8.
