long, shorter than the sessile ovary. Sepals subequal, lanceolate, finely 

 acuminate ; the lateral pair slightly falcate, 15 in. long, widely spreading, 

 many-nerved. Petals very small, broadly ovate, obtuse, only about *12 

 in. long. Lip rather thin in texture, nearly as long as the sepals, 

 lanceolate, acuminate, narrowed to the minutely auricled base ; the upper 

 surface with a central furrow in its basal half and a shallow lamina at 

 each margin of the furrow. Column semi-terete, about three times as 

 long as the petals ; its foot slender, longer than and at right angles to 

 itself. Anther-lip acute.

This belongs to a section of the large genus Bulbophyllum founded 

 by Mr. H. N. Ridley, Director of the Botanic Garden, Singapore, 

 under the name Intervallatse (Journ. Linn. Soc. XXXI, 276) for the 

 reception of a small group of species remarkable for possessing " a tall 

 stiff scape ending in a many-flowered raceme, the flowers of which 

 expand one by one at long intervals of time, the rachis slowly elon- 

 gating as they expand, so that, though in one species as many as eighty 

 flowers are eventually borne on the raceme, no two are open at one 

 time, and many weeks elapse between the opening of the first and last 

 flowers." A similar method of flowering occurs in Blume's genus 

 Dendrocolla, also in the well-known Oncidium Papilio, Lindl., and 

 in some other orchids. This species is intermediate between B. tarde- 

 florens, Ridl. and B. stella, Ridl. (Journ. Linn. Soc. XXXI, 276, 277), 

 but differs sufficiently from both to merit specific rank. A single 

 specimen of it, accompanied by a pencil drawing numbered 434, was given 

 to one of us by the late Father Scortechini many years ago, and as it 

 appears to remain still undescribed, we now publish it. 



The sepals of this are greenish-yellow with reddish markings, and 

 the lip is of a dull carnation colour. The flower is a very striking one 

 from its great size. 



Cikrhopetalum Proudlockii, n. spec. Leafless at flowering-time. 

 Pseudo-bulbs crowded, broadly ovoid, sometimes almost hemispheric, 

 polished, *5 in. long, and about as broad at the base. Inflorescence 1*75 

 in. long ; the peduncle erect, filiform, naked ; the raceme decurved, *5 

 in. long, bearing 6 to 10 flowers each 5 in. long and of a pale straw 

 colour ; floral bract lanceolate, much shorter than the slenderly stalked 

 funnel-shaped ovary. Dorsal sepal lying parallel with the column, 

 oblong ; its apex sub-acute, and slightly reflexed ; the lateral pair twice 

 as long, oblong, blunt, lying close together under the lip, touching by 

 their inner surfaces but not connate, their apices somewhat everted; 

 edges of all entire. Petals as long as the column and much shorter than 

 the dorsal sepal, triangular, entire, the apices aristate. Lip as long as
