2. C. Armitii (after W. E. Armit), F. v. M. Fragm. ix. 49. Plant small. 

 Leaves lanceolate, slightly oblique, 1^ to 2^in. long, 3 to 6 lines broad. Eaeemes 

 ■with the short peduncle about 3in. long. Bracts deltoid, scarcely 1 line long. 

 Sepals scarcely 1 line long, oblong, membranous, narrowed towards the base. 

 Petals roundish, sometimes a little acuminate. Labellum lateral lobes ovate, 

 middle-lobe roundish with inflexed margins. Spur almost 1 line long. Column 

 very short. — Sarcochilus Armitii, F. v. M. Fragm. ix. 49. 



Hab.: Lake Luoie, ir. E. Armit ; Burdekiu River. 



3. C. Nugentii (after L. J. Nugent), Bail., Proc. Roy. Soc. Ql. xi. Stems 

 short, covered by the prominently ribbed bases of fallen leaves, live leaves 2 or 

 3, distichous, linear-lanceolate, 1 to 2in. long, and from 3 to 6 lines broad, 

 shai-ply 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. Racemes 

 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 but no longitudinal veins, greenish and incurved. 

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

 long as the rest of' the labellurn, 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 ; caudicle) 

 bipartite. Capsule not seen. 



Hab.: Black Gin's Leap, a mountain about 16 miles north of Maokay, ,L. J. Nvrjent. 



In some respects this plant resembles an Ornithochilus, and probably upon further examina- 

 tion it may have to be placed in that genus. 



4. C. congestum (crowded). Bail., Proc. Uoy. Soc. Ql. xi. Stems 

 short, the longest seen under 2in. long, the lower part covered by a ribbed 

 scarious bases of fallen leaves. Leaves 2 to 5 straight, linear-oblong, obtuse- 

 acuminate, base more or less cuneate, the longest about l-Jin. long and about 8 

 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 or 2 or none between these and thosa 

 subtending the flowers. Flowers cream-coloured, crowded at the apex forming e 

 head but opening one at a time. Bracts broad, fleshy, pointed, segments of 

 flowers all incurved, resembling those of some of our small-flowered Dendrohiums. 

 Pedicels 3 lines long. Sepals broad-lanceolate about 3 lines long. Petals 

 narrow-linear shorter than the sepals. Labellum long as the sepals, the lateral 

 lobes long and broad, the middle lobe reduced to a truncate end to the labellum, 

 the whole upper surface covered with a dense short white wool, the central scale 

 broad with ciliate margins and recurved coloured point. Spur broad, obtuse, 

 stained with yellow and red, plate at orifice transverse. Column white, semi- 

 terete, scarcely one-third the length of the sepals. Pollen-masses oval, yellow. 

 Capsule slender, 2^in. long.
