to say, “discovered” in their stoves by Mr. J. Barber, 
who was struck with the resemblance of the lip to that of 
a Cypripedium. Dr. Reichenbach further happily remarks, 
that it “ belongs to the Zephyrean company of P.macroble- 
pharis and P. baleniceps.” 
For the specimen here figured the Royal Gardens are 
indebted to Messrs. Low. It flowers all summer. 
Dusor. A dwarf tufted stemless species. Leaf one-half 
- to three-fourths of an inch long, elliptic-obovate, rounded 
at the tip, narrowed into a very slender petiole, flatly 
triangular on a cross section, which shows a promi- 
nent but slender thickening of keel and margins, that 
of the margins rather due to a narrow recurvation of 
the edge, and a mesial furrow on the face, bright green. 
Racemes many times longer than the leaves, subsolitary, 
capillary, drooping, six- to eight-flowered, but with rarely 
more than one flower open at a time; bracts brown, 
sheathing tubes, with a truncate mouth; pedicels very 
slender; flowers nearly one inch long from the tip of the 
dorsal to that of one of the lateral sepals. Sepals oblong- 
lanceolate, concave, white blotched with purple, suddenly 
contracted into a yellow tail almost as long as the limb. 
Petals not half the size of the sepals, ovate, white spotted 
minutely with purple, ending in a long yellow point. Tip a 
linear-oblong, terete, subclavate, solid body of purple colour 
blotched with deeper purple, rounded at the tip, and with 
two teeth opposite the very short claw. Colwmn slender, 
yellowish, keeled behind. Anther a shallow cap, crowned 
with an oblong terete three-toothed appendage.—J. D. H.
