Sikkim, at elevations of about 1,000 feet; in valleys and along the southern face 
of the range; in flower during November and December; Pantling, No. 248. Westward

_ The sepals and petals are bright yellow with brownish-purple spots; the lip is 
white except a patch of yellow with minute brown spots near the apex and a purple 
line round the edges of the sac; the column is pink. This is closely allied to 
S. саїсеоїате, Lindl., with which for many years it has been confused. The two 
plants, although much alike, are not really difficult of separation, Іп the first place 
they live at different elevations and flower at different seasons, 45, calceolare is found 
between 4,000 and 6,000 feet, and flowers during March and April; while S. dasypogon 
is found at or below 1,000 feet and is in. flower during November and December. The 
leaves of 5. dasypogon are broader, and the apical notch is less deep than is the case 
in the leaves of jS. calceolare, and the stem of S. dasypogon is shorter. The coloration of 
the flower of 85, calceolare is constant; but in that of C. dasypogon the perianth may 
be pale or deep yellow, and either without spots or with numerous spots, Finally the 
lips of the two differ. In Ж. calceolare the sac is smaller; the apical lobe is papillose- 
hairy; while in 85. dasypogon the apical lobe has deeply laciniate edges and its upper 
surface is perfectly smooth.

Orch., 223. 
Stem short, pendulous. Leaves narrowly oblong, the apex unequally bifid, the base 
slightly narrowed and jointed to the short wide sheath; length 4 to 11 in, breadth 
75 to 115 in. | Racemes corymbose, many-flowered, much shorter than the leaves, 
the peduncle with several short sheaths. lowers “65 in. across, crowded; floral bract 
broad, blunt. Sepals unequal, spreading, the dorsal obovate-oblong; the lateral pair 
oblong, falcate, narrower than the dorsal. Petals oblong-obovate, shorter than the sepals, 
Lip adnate to the lower half of the column; the base forming a wide short sac, 
nearly parallel with and about half as long as the ovary; side lobes absent; the apical 
lobe at right angles to the sac, semi-circular, its margin and the whole of its upper 
surface, except a triangular yellow pad at the base, covered with white hair-like papilla, 
Column very short, thick. Anther depressed, very shortly beaked; pollinia broadly 
ovoid-elliptic, attached Ly a slender caudicle to a small triangular-cordate gland. Lindl.
