question its inhabiting Jamaica.” My numerous wild specimens 
come from Jamaica, Mexico and Costa Rica: Jamaica, Gilbert 
MacNab! Oaxaca, Mexico, Karwinski! Carthago, Catharina, 
Costa Rica, Oersted! San Jose de Costa Rica, Carmiol! 
Cespitose. Adventitious roots filiform, much bent, dense. 
Rhizome creeping, very strong. Secondary stems nearly terete, 
sulcate, short, with some short sheaths at their very base, a 
longer one beneath the leaf. Leaf cuneate-obovate, blunt at the 
apex, minutely and obscurely tridentate. Flower-stalk much longer 
than the leaf, with a lgulate-acute ancipitous ochraceous sheath 
at the very base. A few short sheaths beneath the very 
long inflorescence occupying the greater part of the flower-stalk. 
Raceme one-sided, distichous. Bracts ochreate, obliquely retuse, 
one-nerved. Pedicelled ovaries exserted. Dorsal sepal triangular, 
fornicate, three-nerved. Inferior sepal oblong, single, acute, or 
bidentate, with two strong lateral nerves and some finer ones. 
Tepals oblong-triangular, three-nerved, generally blunt, sometimes 
very acute, also with serrate borders towards the apex. Lap 
pandurate, bluntly acute, with erect basilar borders (auricule), 
three-nerved, the nerves never reaching the apex, ending 1n clavate 
points. Colunin clavate-trigonous. Borders of androcliniwm with 
a membrane, generally tridentate. Rostellwm triangular, bent over 
the roundish fovea. lowers green, finally yellowish green.

Except to the botanist, the species of Pleurothallis have but 
little interest, and have often been called weeds not worthy of 
cultivation. J must confess to a lively interest in these outcasts, 
some of which are really beautiful when well-grown; and the 
one now under consideration is deserving of favour, producing 
long and elegant stripes of yellow-green flowers, and having 
thick dark green glossy leaves. The figure is from a plant which 
flowered in the Royal collection at Kew.—W. W.S.
