Peristeria Barkeri ; pseudo-bulbis ovatis, profundeé sulcatis, 3-4 phyllis, scapis pendulis multifloris 
foliis subeequalibus ; floribus carnosis fer’ clausis ;_sepalis petalisque subaqualibus concavis obtusis, labelli 
trilobi lobis lateralibus integris erectis, intermedio angustiore basi calloso ; columna aptera leviter pubescente. 
Habitat in Mexico, prope Xalapam. Ross. 
Descriptton, 
PSEUDO-BULBS very large, ovate, deeply furrowed, bearing from two to four lanceolate, acute, 
very much plicated, slightly coriaceous, LEAVES, which are from a foot and a half to two feet or 
more in length. From the base of the pseudo-bulbs issue one or more stout Scares, which are 
pendulous, from one to two feet long, nearly covered with the membranaceous scales for about 
one-fourth of their length, and then changing into a many-flowered RAcEME, on which the Jlowers 
are loosely scattered. FLOWERS sub-globose, fleshy, rather shorter than their PEDUNCLES. SEPALS 
and PETALS nearly equal, concave, obtuse, of an uniform yellowish-orange colour, so slightly 
expanded as almost to conceal the lip. Lip deeply three-lobed, articulated with the elongated base 
of the column, of a@ rich orange colour on its inner side, spotted with red ; its two lateral lobes are 
of «a broadly ovate form, with their margin entire, and are separated at their base by an almost 
square callosity ; the intermediate lobe is longer and narrower than the lateral ones, obscurely two- 
lobed, convex on its outer face, but with its margins turned inward, so as to give it a somewhat 
cucullate appearance. CoLumun about the length of the upper sepal, slightly hairy, destitute of 
WINGS. 
THIS fine Peristeria was discovered in one of those dark ravines, with which the neighbourhood of 
Xalapa abounds, by a Mr. Jouy Ross, who has lately been ransacking the Mexican Flora, in the service 
of Mr. G. Barker of Birmingham, to whose noble collection of Orchidacew he has succeeded in adding 
many new and valuable species :—among which that now represented is not the least striking. It was 
* So called from zeptorepa “a dove,” to which bird the column of the original species, with its erect wings and beak-like anther, bears 
a close resemblance.
