figured by Dr. Lindley in the ‘Sertum Orchidaceum,’ t. 36, dif- 
ferent as the two appear at first sight. The conductors indeed 
of the ‘ Flower Garden’ say that, “ according to the author above 
quoted, we have in this plant much smaller flowers, a simple, co- 
nical, not two-lobed spur, short, very sharp sepals and petals, and 
a pair of great lacerated appendages at the base of the lip; to 
say nothing of the spotting which is so unlike anything among 
Burlingtonias, except maculata.” Now certainly the “pair of 
great lacerated appendages at the base of the lip’’ do not exist 
in our plant. In B. rigida it will be seen that there are four 
elevated and laciniated plates: in our plant the two outer ones 
are marginal. The chief differences, if constant, appear to us to 
be in the smaller size of the entire plant, the entire spur, the 
more acute and spotted sepals and petals, and the greater length 
of the claw of the lip in proportion to the limb or ultimate lobe. 
It is certainly a plant of great beauty and delicacy, and the more 
welcome for flowering in early winter. 
Dzscr. From different parts of a long, slender, radicant stem, 
there arise small oval or ovate compressed pseudobulbs, each 
bearing an oblong, obtuse, subcoriaceous, veinless /eaf. A lesser 
leaf appears at the base of a bulb, and from the axil of this the 
scape springs, a span or more high, slender, erect or nearly so, 
articulated at intervals and bearing small membranaceous bracts 
from each joint. V/owers racemose (or rather a spike, for the 
ovaries are sessile, very long and slender and pedicelliform), dis- 
tichous, moderately large for the size of the plant, inclined, 
scarcely drooping. Calye and sepals connivent, ovate, acute, 
nearly uniform, the two lateral seya/s combined for a great part 
of the length, so as to represent a single broad bifid sepal at the 
back of the lip; all are white, beautifully spotted with deep rose- 
colour. Spur short, deflexed, obtuse (not bifid). Zip nearly or- 
bicular, two-lobed, white, large, spreading, suddenly contracted 
into a broad claw, which has four elevated membranes; the 
lateral ones, marginal and strongly laciniated, may perhaps be 
considered as obsolete lateral lobes: these membranes are buff- 
coloured. Colwma terete, clavate, hairy in front, terminating above 
in two, long, deep, rose-coloured, wavy, erect, but slightly falcate 
and villous, linear-oblong ears: two other subulate reddish pro- 
cesses are seen in front, one on each side the stigma. Anther- 
case very large, helmet-shaped. Pollen-masses two, attached to 
a spathulate caudicle, and arising from an oval gland.
