of Liverpool, who introduced it to the stoves of Europe. It was marked 
“ Cattleya, n. sp.,” and it has many points in common with that Genus, 
especially in the general habit, the large flowers, and in much of their 
structure, but differing remarkably in the labellum and the shortness 
of the column. Wishing, however, to have the opinion of Professor 
Linpiey, he informed me, with his accustomed readiness, “ your 
Trinidad orchideous plant is certainly a new species; but I think it can- 
not be separated from Eprpenprum. The only distinction between it 
and that Genus consists in the labellum being distinct from the column: 
but you will find various degrees of separation between those parts in 
E. asperum, venosum, vitellinum, and bidentatum, which nobody can 
doubt are genuine Ep1pENpRa :—and I have from the Havannah a small- 
flowered species without leaves or stem, the structure of whose lip, 
plates, and lobes and all, is quite yours in miniature.- Should you, 
however, be of opinion that it nevertheless must form a new Genus, its 
character will have to depend upon the large size of the petals, and the 
slight adhesion of the sepals at their base. The latter is, however, but 
a fallacious character, and the former occurs in what I consider true 
Epipenpra :”—In this opinion, expressed by one whose judgment is so 
valuable, I need hardly say, I entirely concur. . 
Deser. Roots consisting of numerous fibres, about the thickness of 
a crow-quill. Stem (or bulb) nearly a foot high, subcylindrical,* but 
swollen in the middle, jointed, obscurely striated, and marked with the 
scars of the old foliage, bearing at the extremity about four oblong, or 
somewhat strap-shaped, distichous, coriaceous, scarcely striated leaves. 
From the base of the upper one of these, and consequently from the 
extremity of the stem, arises the peduncle, a span long, jointed, and in 
part sheathed with small membranaceous scales, bearing a raceme of 
three to four large and highly fragrant flowers. Sepals and petals very 
much spreading, pure white, broadly ovate, rather acute; the former 
rather smaller, and combined at the base, the latter more concave. Iap 
standing forward, sessile on the base of the column, and broader than 
it at the base, spreading, three-lobed, white, with a few purple, small 
oe the side lobes short, intermediate one elongated, lanceolate, entire : 
e disk bears two very large conical divaricating tubercles, which are 
hollow beneath. Column short, white, with a few purple spots at its 
base within, semi-terete, dilated upwards, and somewhat winged. _An- 
ther hemispherical, inserted a little below the extremity of the column 
and in front of it. Pollen-masses four, yellow, in pairs, the caudicule 
replicate and united in pairs. Germen green above, white below, where 
it tapers into the footstalk.
