a large, fleshy, oblon gland, or tubercle, grooved in the 
middle, white, with red lines. Column much shorter than the 
labellum,  semiterete, greenish and white ; its plane side 
beautifully streaked and dotted with red. Stigma large, 
concave, with a triangular Bab ors lip above it. An- 
ther terminal, deep purple, fixed by its back, four celled, 
containing four deep-yellow, plano-convex, waxy pollen- 
masses, joined in pairs by means of the stalks, which are 
pressed against the edges of the pollen-masses, in the same 
way the radicle of the embryo of many cruciferous plants 
is turned up and pressed against the cotyledons. Germen 
resembling a eelice!, club-shaped, streaked and purplish 
upwards. | 
SF ronk the collection of Mrs. Arnotp Harrison, of Aig- 
burgh, near Liverpool, where it flowered in the stove, 
in the month of February, 1828. It was introduced into 
the garden of that lady ‘by her brother, Wittiam Harrison, 
Esq. of Rio, who gathered it in the neighbourhood of that 
It would ap unnatural to arrange this singular Or- 
chideous lant thong with the splendid seule of CarrLEYA: 
yet, in point of essential character, it is very closely allied 
to it, and like it, unquestionably belongs to Mr. Linpuey’s 
tribe of Eprpenprex. I have, however averse to multiply- 
the Genera, already so much increased, of this family, 
felt myself under the necessity of giving a new name to this 
plant, which I have derived from the circumstance of the 
column of fructification being inclosed in, or wrapped round 
by, the labellum*. It is not, however, in this particular 
that it differs from Carrera; but, simply, in the decidedl 
straight, not inate flower, in the less patent S, 
and in its very different habit. | Sa
