bulbs. Leaves elongated, keeled, striate. Flowers not small, in loose racemes 

 pedunculate in the lower axils, the peduncle often long with sheathing rigid 

 ■scales at the base. Bracts usually small. 



The genns, as at present understood, comprises tropical and subtropical species, both of (he 

 New and the Old World, but chiefly from the latter. The Australian species appear to be all 

 -endemic. 



Labellum 3-lobed glabrous except the 2 longitudinal crests 1. C. Hillii. 



Labelluni 3-lobed with 2 longitudinal raised pubescent or fringed plates 



on the disk . . . .... 2. C canaliculaium. 



Labellum il-lobed without longitudinal plates. Leaves very long and 



mostly lin. broad 3. C albvciflorum. 



Labellum undivided without longitudinal plates . . 4, C. suave. 



1. C. Hillii (after Walter Hill), F. v. M.in PwijeVs Gartenf. 138. (1879) ; 

 Fragm. xi. 88. In many characters this species agrees with V. canalicitlatum. 

 I'he leaves, however, are of thinner consistency, prominently 3-nerved, broad- 

 linear. Eacemes of few flowers ; bracts, somewhat long. Sepals oblong- 

 lanceolate, acute, slightly longer than the petals. Labellum 3-lobed, glabrous, 

 bicristulale, the middle lobe nearly three times as long as broad. 



Hab.: Mulgrave ranges, on Eucalypt tree, Walter Hill. 



2. C. canaliculatum (channelled), 77. Br. Prod. 331 ; Ihnth. Fl. Austr. 

 vi. 302. Leaf-stems or pseudo-bulbs usually 2 to 4in. long. Leaves elongated, 

 narrow, keeled, channelled above, striate, the upper ones often Gin. to 1ft. Jong 

 ■or even more, the lower ones short. Racemes from the lower axils often 1ft. 

 long including the peduncle, the sheathing scales at the base rather rigid, the 

 bracts small and spreading. Pedicels J- to lin. long. Sepals and petals oblong 

 or lanceolate, 5 to 7 lines long. Labellum rather shorter than the sepals, 

 •distincly 3-lobed, the lateral lobes decurrent along the claw, the middle lobe 

 broadly ovate or almost rhomboidal, as long as the lower part, papillose on the 

 upper surface ; the disk between the lateral lobes with 2 longitudinal rais&d lines 

 •or plates- slightly pubescent or shortly fringed. Column about as long ha the 

 lateral lobes, slightly incurved, with 2 narrow longitudinal wings.- — Lindl. Gen.

Hab.: Broadsound, B. Brown; Cape York, (Botanical Magazine) ; Herbert's Creek, Bowman > 

 •Cape Kiver, Fitzalan ; Burnett, Haly ; Cooper's Creek, F. v. U.; also on the tropical forest trees. 



The form of the flowers slightly, and the colouring considerably, differ in plants growing 

 in different localities of this widely-spread species, but I have not seen distinction enough to 

 separate them into named varieties 



In some the flowers are brown with green margins others yellow blotched with red and the 

 labellum dull-white spotted with red as noticed by Mr. Bentham. 



3. C. albuciflorum (flowers like those of Albuea), F. v. M. Pragm. i. 188 ; 

 Benth. Fl. Austr. vi. 303. " Dampy-arapy," Port Curtis; " Bungkiam," Tully 

 River, Both. Stems or pseudo-bulbs often 1ft. long. Leaves attaining 2ft. or 

 more and often lin. broad, keeled underneath, channelled above, and striate. 

 Racemes including the peduncle 1 to 2ft. long, axillary, with sheathing scales at 

 their base. Bracts small, at length spreading or reflexed. Pedicels rather rigid, 

 4 to fin. long. Sepals and petals greenish yellow, about 5 lines long, rather 

 brown outside, more obtuse than in C. canaliculatum, the sepals broadly oblon", 

 the petals rather narrower. Labellum nearly as long as the sepals, red at the 

 base, yellowish above, 3-lobed as in C. canaliculatum but without the longitudinal 

 plates of that species, of a rather thicker consistence and not quite so broad. 

 -Column with a prominent angle in front, the apex truncate. 



Hab.: Moreton Bay, W. Hill ; Eockingham Bay, Dallachy ; Mount Dryander, Fitzalan, 

 Very abundant.
