to no. 1680 of Mr. Loddiges’ collection, which requires further 
examination. Pilumna laxa itself has very thin flat pseudo- 
bulbs, and leaves marked beneath with small purple spots. 
Our drawing was made in the garden of the Horticultural 
Society in October, 1845. Fig. 1. represents the column and 
lip; 2. pollen-masses and gland; 3.a pollen-mass apart: the 
hairiness of these bodies represented by the artist, escaped 
our own observation. © 
The species, now represented, was found in the woods of 
Popayan by Mr. Hartweg. | 
It should be treated in the same manner as most of the 
other Orchids which are natives of Mexico and Guatemala. 
A cool stove, which is shaded from bright sunshine during 
the summer months, and where a damp atmosphere can be 
kept up, suits it very well. It should be potted in turfy peat, 
. in a well-drained pot, and liberally supplied with water during 
the growing season. When the growth is perfected for the 
season less water should be given, and the plant allowed a 
period of rest. 
Like all the other plants belonging to this tribe it is mul- 
tiplied by dividing the pseudo-bulbs, and this is best done 
just before the spring growth commences.
