50 ANNALS OF ROYAL BOTANIC GARDEN, CALCUTTA. 
Except in habit of growth, which approaches that of S. distichum, this is not nearly allied to any 
other species of the genus. The solitary or fascicled flower, sessile on leaf-opposed brown tubercles of the 
stem, which are covered with microscopic bracts, is very peculiar. 
The drawing is inscribed “no label sent, H. В. C., 16-7-81 The analyses I—3 are on the 
drawing; those marked Al to A4 are by Miss Smith at Kew under my eye from Penang specimens.

HAB.— SIKKIM HIMALAYA (Ie. Cathcart). 7 and Assam (Ic. іп Herb. Calcutta). 
Stem 1—3 feet, as thick as a swan’s quill, rooting at the base only, cylindric 
and clothed with sheaths below, leafy (and flattened?) above; internodes 1 in. Leaves 
1—10 by $—1 in, spreading, flat, deeply channelled, bright green. Racemes with the 
rather stout ascending terete green peduncle 3—5 in.; bracts very small, ovate, brown ; 
pedicels slender, with the ovary % in., usually sigmoid, all curving to one side; flowers 
2 in. long. Sepals and petals 4 in. long, spreading, white or cream-coloured with pink 
midrib. Lip white or yellowish, spotted or blotched with pink. Column (rather rostellum) 
‚small. Anther flat, acute; pollinia globose, strap slender; gland small lanceolate. 
A very distinct species of the section which I have called Speciose, to which belong the well. 
known S. ampullaceum (Aerides ampullaceum, Roxb.) and 8. curvifolium, Lindl. (S. rubrum, Lindl.), 
. from both of which it is at once distinguished by the small lax-fld. one-sided raceme and curved 
spur. 
The plate is a reproduction of a portion of a full-sized drawing in the Cathcart collection at 
“Кем. Of the figures, that of the section of the lip represents the gland as misplaced ; it should be within 
the mouth of the lip below the base of the midlobe, as badly represented at figure 8. Lindley by an 
oversight attributed the specific name of pallens to Mr. Cathcart, "who never attempted to name a
