D. Dalhousieanum.—This is a noble plant, requiring 
considerable space if it is to be grown in anything like 
perfection, as it attains a height of 3ft. to 4ft. The stout, 
erect pseudo-bulbs are veined with purplish crimson in 
a young state; they become hard and woody with age, 
and they usually continue to produce flowers for several 
years in succession. The leaves are lance-shaped, broad, 
from 4in. to 6in. long. The flower-spikes, which are some- 
times in pairs, are produced near the apex of the leafless 
pseudo-bulbs, each raceme bearing from three to ten 
flowers; these are very large (from 3in. to 5in. across) ;
