characters (especially those of the disk and toothed margins 
of the lip). As it is, #. evectum is by far the handsomest 
form of the section that has hitherto flowered in England, 
(with the exception of those with branched racemes), and 
from its free growth and facility of cultivation, will always 
prove an acquisition in the cool Orchid house. It was pro- 
bably sent by Purdie from the New Grenadan mountains, 
but all record of its origin has long been lost. 
Descr. Stems fascicled, swollen at the base, three to five 
feet long, flexuous, branched, as thick as a swan’s quill, leafy 
towards the tips. Leaves four to six inches long by one and 
a half to two inches broad, sessile, oblong-lanceolate, obtuse, 
emarginate, coriaceous, plane, sheaths rather short. Peduncle 
long, slender, clothed with distant, appressed scarious bracts, 
the lower of which are sheathing with subulate points, the 
upper small subulate without sheaths. Raceme four to six 
inches long, by three to four inches in diameter, lax, subcy- 
lindric, many-flowered ; bracts small, subulate; pedicels spread- 
ing and recurved, with the slender ovary one to one and 
a half inches long. Perianth one and a quarter to one and 
a half inches in diameter, bright rose-purple. Sepals and 
petals similar, narrow obovate, obtuse. Zp adnate to the 
column, rather longer than the sepals, 3-lobed nearly to the 
base, lobes all deeply cut and fringed; lateral reflexed, 
cuneate-quadrate; middle lobe larger, divided into two wide 
spreading, lacerate, subquadrate lobes, with an acute sinus 
and apiculus between them ; disk with. an obtusely triangular, 
obscurely-lobed callosity, and two linear parallel tubercles at 
the base.—/J. D. H.
