380 ORCHIDS: 
with rosy purple; lip three-lobed, narrow in the middle, 
the lobes concave, pure white; crest fleshy, five-toothed. 
The flowers are fragrant, and remain fresh for about 
a month. Well-grown examples of this species are not 
uncommon in collections, and when bearing their numerous 
spikes of pretty flowers in autumn are very ornamental. 
The plant requires cool-house treatment, thriving when 
grown in a pot of peat and sphagnum, and supplied with 
moisture at all times. A native of Mexico; introduced in 
1845. Syn. O. albo-violaceum.

Var. album has flowers wholly white. 
0. Jonesianum.—A beautiful-flowered species, distinct in 
habit, and a very effective plant in every way. It has 
scarcely-perceptible pseudo-bulbs, and thick, fleshy, rush- 
like leaves, which usually hang downwards, and are from 
gin. to 12in. long. The flower-spikes are developed from 
the base of the last-matured growth, and vary in length 
from 6in. to 2ft. The strongest spikes bear as many as 
a dozen flowers, each of which is 2in. across; sepals and 
petals equal, oblong, wavy, r4in. in length, and coloured 
creamy white, with large spots of chestnut; lip large, 
broad, flat, with small, serrated, yellow side lobes, the 
blade white, with a few crimson spots towards the base; 
crest composed of numerous yellow tubercles. Consider- 
able variety in the size and marking of the flowers 
characterises this species. When first introduced it was 
treated as a cool-house plant, but it thrives best when 
grown on blocks in a moist, tropical house, in a rather 
sunny position. Its flowers are developed at various times, 
usually in autumn and winter. Introduced from Paraguay 
in 1883.
