358 ORCHIDS. 
0. pulchellum.—A distinct and pretty little kind, with 
pure white, deliciously fragrant flowers. Pseudo-bulbs long, 
narrow, thin, and two-leaved. Leaves grass-like, rather 
stiff, gin. to 12in. long. Flowers borne on erect spikes, 
suggestive of lily of the valley. There is a small, yellow 
blotch on the crest of the lip. The flowers are more 
fragrant at night than in the day, and are developed 
in spring, lasting about six weeks. This charming little 
Orchid is easily grown, and never fails to flower. It 
prefers cool treatment, but may be grown along with 
Cattleyas; it likes plenty of moisture. Owing to the erect 
habit of the spikes, the flowers are arranged with the lip 
uppermost, and appear to be upside down. Introduced 
from Guatemala in 1840. Syn. O. Egertontz.

0. ramosissimum.—A _ distinct plant, with oblong, 
flattened pseudo-bulbs, bearing each a single leaf about 
Ift. in length. Spike 3ft. or more long, branching, and 
bearing numerous flowers 2in. across, with narrow, wavy 
sepals and petals, and a narrow, reflexed lip; the colour 
is pure white, spotted with pale purple. Introduced from 
New Granada in 1871. It should be grown in the cool 
house, where its flowers are developed in March and 
April. The pretty, graceful flowers have been likened 
to large spiders. 
0. Rossiii—This is one of the best and most popular of 
the smaller kinds. It grows and blossoms freely, and its 
beautiful and lasting flowers are produced during the winter 
months. It may be grown in an ordinary greenhouse 
along with O. crispum, &c. If we had to make a selection 
of six Odontoglossums, this would certainly be one of them. 
It has small pseudo-bulbs, with one short leaf each. The 
spikes are 6in. long, and bear two to five flowers, each
