1. C. campestris (a field plant), R. Br. Prod. 320; Bmth. Fl. Austr. vL 

 315. Stem usually rather stout, from under 1ft. to above l^ft. high, with a rather 

 long leaf and 3 to 5 flowers, but sometimes with the habit of 0. paludosus. 

 Sepals in the typical form 4 to 5 lines long, the petals much shorter. Labellum 

 iin. long or more, obovate or obovate-oblong, the margins and surface covered 

 with long purple fringes except near the base where (in the same typical form) 

 there is a raised plate or thickened surface quite smooth and extending more or 

 less along the centre of the narrow part of the labellum, and the end is produced 

 into a linear or lanceolate smooth often flexuose point varying much in length. 

 Column-wings rather broad and dilated in front into a variously-shaped lobe or 

 angle with a dark-coloured gland inside, the two wings not at all connected in 

 front. Anther bent forward at the base, recurved and acuminate or rostrats 

 upwards.— Lindl. Gen. and Sp. Orch. 459 ; Bot. Mag. t. 3187 ; Hook. f. FL 

 Tasm. ii. 15, t. 106 A; Eeichb. f. Beitr. 21; C. herbacem, Lindl. I.e.; Fitzg. 

 Austr. Orch. i., Pt. 4. 



Hab.: Southern localities. 



Var. (jrandiflora. Flowers 1 to 3, larger than in the common form, and altogether resembling 

 C. pcdudosiis, the labellum covered with fringes or linear calli from the base, but without 

 intramarginal appendages of that species, and the glands of the column-wings as in 0> 

 caTn2}eitris. 



Hab.: Islands of Moreton Bay. 



2. C. paludosus (a swampy land plant), R. Br. Prod. 320; Benth. FL 

 Austr. vi. 316. Usually more slender than C. campestris, with a long leaf and 

 only 2 or 3 rarely 4 flowsrs, often but not always larger than in that species.- 

 Sepals usually 7 to 8 lines long ; petals not half so long, strongly veined. 

 Labellum covered with the long fringes or cilia, shorter and much crowded 

 towards the base, with 2 longitudinal but short and much raised plates near the 

 base resembling auricles but intramarginal, not strictly marginal as figured (C 3) 

 in Endlieher's plate, the terminal smooth point of the labellum usually long 

 flexuose and linear. Column-wing produced behind the anther to about it» 

 length, broadly rounded in front on each side, without the glands of C. campesti-is. 

 Anther as broad as long, very obtuse,^ neither acuminate nor rostrate. — Lindl. 

 Gen. and Sp. Orch. 459; Endl. Iconogr. t. 14; Eeichb. f. Beitr. 22; Fitzg. 

 Austr. Orch. i. Pt. 4. 



Hab.: Cooper's Plain, Di: G. Prentice; and other southern localities. 



45. CHILOGLOTTIS, R. Br. 



(From cheilos, a lip, and r/lotta, the tongue.) 



Dorsal sepal erect, incurved, concave, contracted at the base ; lateral sepals 

 narrow-linear or terete ; petals lanceolate falcate. Labellum on a very short 

 claw, ovate or obovate, undivided, the disk with variously arranged calli. Column 

 elongated, incurved, winged. Anther terminal, erect, 2-celled ; pollen-masses, 

 granular. — Terrestrial herbs, with small underground tubers. Leaves 2, radical 

 or nearly so. Scape 1 -flowered, without any empty bract below the one- 

 subtending the terminal pedicel. 



Australian species are endemic. 

 Dorsal sepal 5 to 6 lines long, much contracted at the base ; lateral sepals 



linear-terete. Calli of the labellum slender, scattered over the whole disk . 1. C, diphylla^ 



Dorsal sepal spathulate, 7 lines long. Calli of the labellum a large recurved 

 one near the base, and 9 or 10 flat ones along the centre, surrounded by 

 slender one . 2. C, trilabra^
