length of the spur. The former, in the specimen before us, 
measures seven inches across, and the spur one foot in length, 
so that if the spur were set on at the edge of the flower, instead 
of the middle, it would rather exceed than fall short of the size 
attributed to it. ‘This flower is of a uniform, pure ivory or yel- 
lowish white, and it has the merit of possessing the odour of 
the white Garden Lily, Lilivm candidum. The plant continually 
attracted the attention of Mr. Ellis as he travelled through its 
native woods; more than one of his photographs includes trunks 
of trees loaded with this prince of Orchideous plants, and it is 
frequently the subject of his description and admiration. Indeed 
no one has travelled in tropical regions, possessed of a greater 
love of nature, especially of vegetable forms, than this gentle- 
man. It should be borne in mind also that he introduced to our 
stoves the still more remarkable Lace-leaf, Ouvirandra fenestralis, 
and other rarities. 
Duscr. The plant, including the leaves, does not appear to ex- 
ceed two feet in length,—so that the flowers are sometimes as long 
as the plant,—simple or bearing one or two branches; attached 
to the trunks of trees by wiry fibres, rather densely clothed with 
distichous, spreading, more or less recurved leaves, of a broad 
oblong form, thick and fleshy, dark-green, imbricated, carinated 
at the base. Peduncles solitary, axillary, bearing from two to 
four gigantic ivory-white fragrant flowers, each subtended, at 
the base of the ovary, by a broad, ovate, coloured dract. Sepals 
and petals equally spreading, nearly uniform, three inches long, 
from a broad base, gradually acuminated, somewhat fleshy. Lap 
equal in size with sepals and petals, from a cordate base, ovate, 
acuminated, near the middle, on each side, coarsely and irregu- 
larly serrated ; from the base of this, beneath, depends the very 
long, terete, but gradually tapering spur, one foot in length, green 
in colour. Column very short, thick, with two broad wavy wings 
on each side the stigma, which almost conceal that organ. A”- 
ther-case helmet-shaped, white, with a narrow orange-coloured 
margin. Pol/en-masses two, ovate, waxy, each attached to a 
somewhat linear gland.
