leaf-opposed; the peduncle about 1:75 in. long, with two tubular sheaths. Flowers six to 
eight in an umbellate raceme, "85 in. wide (measured across the lateral sepals); floral bract 
broadly oblong, blunt. Sepals and petals fleshy, sub-equal, slightly reflexed, oblong- 
oblanceolate, blunt. Zip shorter than the petals, adnate to the column almost to its 
apex, the base forming a wide but rather shallow sac with a rudimentary septum 
inside it; side lobes very narrow, entire or almost obsolete; apical lobe reniform, 
obscurely 3-lobulate, the edges fimbriate-erose; the upper surface with a large, broadly 
ovate, fleshy, glabrous patch near the base and with a broad thin margin, papillose- 
pubescent on the surface. Column short, thick. Anther dome-shaped, beaked in front; 
pollinia globular; caudicle filiform, dilated at base and apex; gland elongate, bifid. Lindl.

The sepals and petals are either of а dull pale green, flushed and mottled with dull 
brown, or they are of a uniform yellow colour. The lip is white, the fleshy dise on 
its upper surface being bright yellow spotted with dull red, and the fundus of the sac 
externally being greenish-yellow. The column is purple. 
This species is allied both to 8. caleeolare and to Ж, dasypogon, but not so much to 
cither 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 which form an umbel rather than a corymb. The sac of the lip 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 trilobulate, while in those it has 
no trace of lobulation. There are further differences in the apical lobe of the lips of 
the three species, which may be shortly summarized thus; that of S. dasypogon is glabrous 
with laciniate but not lobulate edges; that of 8. acutifolium has trilobulate, fimbriate- 
erose edges, and its upper surface has a large thickened smooth spot with a broad thin 
margin covered with papillose hairs; while that of C. caleeolare is not lobulate, and its 
upper surface is papillose-hairy, except a small glabrous patch.
