CLEISOSTOMA, Blume. 

 C. Niigentii, n. sp. (After the discoverer, L. J. Nugent). 

 .Stems short, covered by the prominently ribbed bases of fallen 

 leaves, live leaves 2 or 3 distichous, linear-lanceolate 1 to 2 in. 

 long, and from 3 to 6 lines broad, sharply keeled, the longitudinal 

 nerves only seen in the dry or partially dry state ; all much blotched 

 with deep-red or purple on the specimens examined. Kacemes 

 spike-like, erect, often longer than the leaves. Bracts small 

 but the lower empty one rather larger than those subtending 

 the flower, and somewhat spreading or recurved. Flowers 

 small, numerous, on very short pedicels. Sepals somewhat 

 spathulate, 1 line long, incurved, greenish, towards the tips, the 

 lateral ones adnate to the basal projection of the column. 

 Petals shorter and broader than the sepals, with thick midrib 

 "hut no longitudinal veins, greenish and incurved, Labellum 

 white, as long as the petals, the basal pouch not quite so broad 

 hut as long as the rest of the labellum, with no internal 

 appendage ; the lateral lobes very short with coloured margins, 

 embracing the column ; scale in front of the saccate end or 

 middle lobe membranous. Column short, with broad green, 

 ciliate wings. Anther lid purple. Pollen-masses 2 nearly 

 spherical ; candicle bipartite. Capsule not seen. In some 

 respects this plant resembles an Ornithochilus, and probably upon 

 further examination it may have to be placed in that genus. 



Hab. : Black Gin's Leap, a mountain about 16 miles north of Mackay.

C. congesta, n. sp. Stems short, the longest seen under 

 2 in. long, the lower part covered by the ribbed scarious bases 

 of fallen leaves. Leaves 2 to 5 straight, luiear-oblong, obtuse- 

 acuminate, base more or less cuneate, the longest about 1^ in. 

 long, and about 3 lines broad, the veins in the live leaf 

 obscure from the coriaceous nature of the leaf, but both the 

 longitudinal ribs and cross veinlets plainly visible in the dried 

 specimens. Peduncle usually shorter than the leaves, with 1 or 

 2 scarious sheathing bracts at the base, and 1-2 or none between 

 these and those subtending the flowers. Flowers cream-coloured
