0. Papilio—This is the Butterfly Orchid, which most 
people are acquainted with and admire. The flower is 
very remarkabie in form, even for an Orchid, whilst in 
beauty it ranks among the best. The pseudo-bulbs are 
roundish, compressed, wrinkled, and so crowded as to over- 
lap each other; they are one-leaved, each leaf being from 
6in. to 8in. long, 2in. broad, leathery, deep olive-green, 
mottled with reddish brown. The flower-scape is basal, 
from 2ft. to 3ft. long, flexuose, jointed, flattened, winged, 
with a sheath at the top, from which the flowers spring, 
one at a time. The three sepals are all erect, 3in. long, 
narrow, and purplish-coloured ; the two lateral petals are 
oblong, crisp-edged, curved downwards, about 2in. long, 
bright yellow, with bands and blotches of red; the lip is 
stalked, with a roundish blade, 14in. across, very wavy and 
crisped at the edge, yellow, mottled or margined with 
bright cinnamon-brown; the column is short and winged. 
This plant is common in the West Indies and Venezuela, 
growing upon trees, and producing a very fine effect when 
in flower. Under cultivation here it is almost always in 
blossom, the same scape continuing to develop flowers for 
several years. It requires tropical treatment, with plenty 
of moisture and sunlight all the year round, and thrives
