Opontoe.ossvm hastilabium. Lindl. in Orchidacee Lindeniane, p. 16. ined. 
A truly lovely Orchideous plant, wholly new to our living 
collections, but known to Dr. Lindley through Linden’s specimens 
of New Grenada. Sent to Kew by our Collector, Mr. Purdie, 
who gathered it in woods on the route from Santa Martha to the 
Sierra Nivada. Linden detected it in the province of Pamplona, 
at an elevation of 2,500 feet. The flowers are numerous on the 
raceme, large, handsome, elegantly varied with pale green purple 
and white, and moreover highly fragrant. Our drawing was 
made from the plant at Syon Gardens, where the species blossomed 
in August, 1846. 
Descr. Pseudo-bulés oblong, compressed, ribbed, pale green, 
while young sheathed below by the bases of two /eaves; two 
other leaves spring from the summit of the pseudo-bulb, these 
are linear-oblong, obtuse, subcoriaceous, without strie. Scape 
from an axil of a lower leaf at the base of the pseudo-bulb, a 
foot and a half or two feet long. Bracteas long, membranaceous, 
lanceolato-subulate, deciduous. Sepals and petals” spreading, 
uniform, lanceolate, much acuminated, pale green, with copious 
transverse purple dots or lines. Lip large, as long as the peri- 
anth, its entire shape broadly hastate ; in other words, three- 
lobed, the two lateral lobes forming two horns at the base, the 
DECEMBER Ist, 1846.
