when fully exposed to the sun and light, this is the one. It will grow well 

 enough when shaded, but in order to flower it well it must be fully exposed, 

 more especially as its young growths approach their full development. Our 

 plants here have been grown in the comparatively hot and dry temperature of a 

 fruiting pinery, where their growth, though short, has been fully ripened ; and it 

 is no uncommon circumstance to see small bulbs three or four inches long pro- 

 duce flowers when so treated. Still, the longest jDscudobulbs are produced in a 

 moist, warm temperature. It will do well grown in a warm vinery or plant- 

 stove, but should not be included in the " cool " list, or disappointment would in 

 all probability ensue.

 well established, after which it will require but little attention. When well 

 grown it is a most profuse bloomer, flowering from the old back bulbs for two or 

 three successive years. Dr. Ainsworth's plant, though a fine specimen, has only 

 seven pseudobulbs, still it bore this year five spikes of glowing rosy-purple 

 flowers, two of which were very fine when exhibited. One of the greatest draw-
