DESCRIPTION. 
上 SEUDOBULBS rather long and narrow, compressed, about 3 inches in length. LEAVES, one on each pseudobulb, less than a 
span long, membranous, sharp-pointed, narrowed at the base into a channelled petiole. Bracıs about an inch long, 
scariose, very acuminate. oarn longer than the leaves, only partially covered by the bracts, bearing from 2 to 
half-a-dozen flowers of a very delicate texture, and of snowy whiteness with the exception of the yellow crest on the 
lip and a few brown blotches on the lower half of the sepals and (though in a less degree) of the petals also. 
SEPALS rather narrow, oblong, acute. 了 BTALS broader than the sepals and waved at the margin. Lie with a 
heart-shaped crenulate plate (occasionally suffused with a rosy tint), and a yellow 8-lobed callus at its base, the 
front portion of which is longer than the lateral ones (which are turned inwards from the base upwards), and split 
into two divergent members. COLUMN slender, clavate, wingless. 
This pretty species was first described by Professor Reichenbach, from materials derived from the collection of 
Mr. Warner, of Broomfield, in compliment to whom he named it. It also flowered with the late Mr. Cauty, of 
Liverpool, who kindly sent me the specimens from which the figure was prepared, but these were smaller and less rich 
in their colouring than those of Mr. Warner. 
We have no precise information as to the locality where O. Warnerianum grows wild, but there can be no doubt 
that it comes from some part of Mexico, whence we have other species, e.g. O. Rossii, O. Ehrenbergü, and O. nebulosum, 
to all of which it is nearly allied. Tt flowers in the later autumn and winter months, but like most of the other 
members of its section (Leucoglossum), is of a delicate habit, and requires to be very carefully handled. It seems to 
prefer a moderate heat and perhaps a slightly drier atmosphere than that in which the New Granada and Peruvian 
Odontoglossa evidently delight; the compost or materials in which the roots grow, should on no account be allowed to 
become sodden.
