Description, 
PseEvupo-BULBS oblong, slightly compressed, 2 to 4 inches long; LEAVES somewhat coriaceous, 
narrow-ligulate, from a foot to a foot and a half in length, placed some at the base, and others at 
the apex of the pseudo-bulbs. Scare from 2 to 4 feet high, having, at considerable intervals, short 
loose pointed Brac ts, and terminated by a many-flowered secund RACEME. SEPALS and PETALS 
oval-lanceolate, the latter narrower and shorter than the former; both are of a lively green, 
irregularly blotched with reddish chestnut. Lip of a purplish rose-colour, heart-shaped, destitute of 
teeth or tubercles at its base, but bearing two upright plates (which cohere in the centre) on the claw 
by which it is articulated with the column. Coxumy only half the length of the lip, furnished with 
two rounded slightly decurved Wings. : 
OUR figure of this elegant new species of Cyrtochilum, is derived from specimens obligingly commu- 
nicated to us from Bicton, near Exeter, the well-known seat of Lord Rotts. ‘The name which we have 
given to it will not merely serve to commemorate the circumstance of its having flowered there, but is also 
designed as an acknowledgment of the many obligations which Botany owes to the noble proprietor and his 
accomplished Lady. 
Many a noble Cyrtochilum+ has yet to be introduced from Mexico, in which country the head-quarters of the 
genus would seem to be fixed. Three species, erroneously referred to Odontoglosswm, have been described by La 
Liave and Lexarza, from the neighbourhood of Valladolid alone ; and several others, gathered in Oaxaca by Baron 
Karwiysk1, occur among the Orchidacee of the Royal Munich Herbarium, for the opportunity of examining which we 
* So called from kvpros, convex, and xe?Xos, a lip ; in allusion to the form of the labellum of some of the species. 
+ Only two other species of Cyrtochilum have as yet blossomed in English collections ; and Mr. R. Harrison, of Liverpool, has had the 
honour of flowering them both for the first time. One of these (C. mystacinum, Linn. MSS.) is a native of Peru,—the other (C. flavescens) is said 
to be a native of Mexico; but as we have no evidence, beyond that of report, to establish the fact, and as we know positively (from the circumstance 
of its existing among M. le Baron B. Detrssert’s splendid series of drawings) that it occurs in Brazil, we have little doubt that its habitat is exclusively 
confined to the latter country.
