The sepals and petals are pale green with large roundish brown markings j the sac
of the lip is bright yellow with brownish-red markings, and the apical lobe, except the
smooth yellow speckled pad at its base, is pui-e white; the column is reddish. This

The flowers of tliis are yellow, boldly spotted with brownish-pm-pîc, the fimbrioe
at the apex of the hp alone being white. The column is pinkish. This species is
allied to S. calceolare^ S. dasypogon, and S. aeutifoliwn, but differs from all in having
a veiy long slender stem with elongated linear leaves and short umbels bearing only
tluree or four flowers.

Sikkim, at elevations of about 3,000 feet; in flower during November and December;
Pantling, No. 3. Khasia Hills.
The sepals and petals are either of a dull pale green, flushed and mottled with dull
brown, or they are of a uniform yellow colour. The lip is white, the fleshy disc on
its upper surface being bright yellow spotted with dull red, and tho fundus of the sac
externally being greenish-yeUow. The column is purple.
This species is alUed both to S. calceolare and to S. dasypogon, but not so much to
either as those are to each other. It grows at elevations intermediate between them.
This, unlike the other two, has an elongated stem and an inflorescence bearing not more
than eight flowers wliich form an umbel rather than a corymb. The sac of the hp is
also more shallow than in those, and the coloration of the sepals and petals is different.
The apical lobe of the lip is in this distinctly trilobulatc, while in those it has
no trace of lobulation. There are further differences in tho apical lobe of the Hps of
the tluree species, which may be shortly summarized thus; that of S. das'jpogon is glabrous
with laciniate but not lobulate edges; that of S. acutifolium has trilobulatc, fimbriateerose
edges, and its upper sui-face has a large thickened smooth spot with a broad thin
margin covered with papillose haii's; while that of C. calceolare is not lobulate, and its
upper sui-face is papillose-hairy, except a small glabrous patch.
