Epidendrum Barringtonie, “ Sm. Ic. Pict, t. 15.” 
Roots several, cylindrical, waved, fleshy fibres, springing from the lower part 
of the bulb. Bub three inches or more in height, and nearly as much in 
diameter, compressed, but four-sided, each side having a slightly promi- 
nent line down its centre. From the summit of the bulb spring, in this 
specimen, three ovato-lanceolate leaves, nearly a foot in length, tapering 
at the base, acute at the extremity, waved at the margins, the surface 
many-neryed and plicate, the colour rather a dingy green, paler beneath. 
At the base of the bulb, and from among the roots, arises a single scape, 
scarcely longer than the bulb, cylindrical, green, sheathed, with large, 
ovate, involute and striated, brown scales, 1-flowered. Flower largé: Pe- 
tals spreading, ovato-lanceolate, very obscurely striated, the three upper 
ones the smallest, the two larger uniting and running down at their base 
behind, into a large obtuse subdidymous spur, divided almost down to the 
base in front : all are of a rather deep yellow-green colour, tinged with 
brown at the extremity. Lip oblong, an inch and a half or more in length, 
but shorter than the petals, erecto-patent, almost pressed to the column, 
and articulated to it at the base, white at the lower half, the upper orange- 
flesh-coloured, three-lobed, the two side lobes small, incarved, the central 
one large, fleshy, subconcave, fringed at the margin: there are also two 
elevated fleshy lobes, occupying the lower half, decurrent with it, striated. 
Column long, white, uniting the bases of the petals, and | running down 
into the spur, the upper part free, slightly curved. Anther operculiform 
gs slightly attached behind to the back of the column, 2.celled.
