The most remarkable of all the Brassavolas (of which genus 
Dr. Lindley enumerates fifteen described species), and among the 
most singular of Orchideous plants, a native of Honduras, whence 
it was introduced by Mrs. M‘Donnell, the lady of the late 
Governor. It flowered in the Orchideous house of the Royal 
Gardens in June, and is deliciously fragrant. - 
Duscr. Pseudo-bulbs elongated, stem-like, compressed, jointed, 
the joint sheathed, terminated by a solitary elliptical, glaucous, 
thick, fleshy, but flattened though carinated Jeaf. From the base 
of the leaf arises the peduncle, compressed and sheathed, termi- 
nated by a solitary, very large, fragrant flower. Sepals and 
petals nearly similar, oblong, spreading, pale-purplish_ green, 
faintly striated, the petals paler and rather broader. Lip very 
large, cucullate, cordate, white or cream-coloured, surrounding 
entirely the column, faintly striated or nerved, the margin nearly 
all round cut into a broad hair-like fringe; the disk furnished 
with a large green tubercle. Column semiterete, winged. Stigma 
with three furrows. From the back of the clinandrium mses &
