238 ORCHIDS: 
E. purum, E. radiatum, &c. Only those known to possess 
good ornamental flowers are, however, described here. 
Culture.—Nearly all the cultivated Epidendrums thrive 
when grown in the Cattleya-house and treated as if they 
were Dendrobiums. E. vitellinum and E. bicornutum are 
exceptions; their treatment is given under their respective 
names. 
E. atropurpureum.—In this species the pseudo-bulbs 
are ovate and wrinkled, bearing a pair of narrow, dark 
green, leathery leaves. From between the latter is pro- 
duced a long spike, bearing several large flowers, which 
have spreading, oblong sepals and petals, of a dark brown 
colour, greenish at the base; the lip is large, spreading, 
three-lobed, and pure white, with a feather-like blotch of 
reddish purple at the base. A very handsome species, 
well deserving a place in the smallest collection of inter- 
mediate-house Orchids. It blossoms in spring and early 
summer. It is a native of America, from Costa Rica 
to New Grenada, and was introduced in 1836. Syn. 
E. macrochilum. 
Botanical Magazine, t. 3534. 
Var. roseum has purple sepals and petals, and a rose- 
coloured lip. 
E. aurantiacum.—A free-growing plant, with pseudo- 
bulbs and foliage very similar to those of Cattleya 
Skinneri. The flowers are produced in short, arching 
recemes, which spring from the apex of the last-matured 
pseudo-bulbs; they are lin. across, the sepals and petals 
nearly equal, spreading, pointed, and of a bright cinna- 
bar-red, a shade darker than the colour of those of 
Lzlia harpophylla; the lip is small, incurved at the edges, 
and lined with crimson on an orange ground. The blossoms 
appear in February or March, and last several weeks. 
The plant should be treated as advised for Cattleya
