1578 CXXVII. ORCHIDE^. [Pterostylis. 



long, 3 or 4 lines broad, prettily veined, the 5 longitudinal ones not more 

 prominent than the the others. Scape 1-flowered, about 3 or 4in. high, with a 

 single empty bract near the middle and another immediately under the flower. - 

 Segments of flower all with long filiform points altogether not exceeding 9 lines 

 in length. Labellum shorter than the segments, claw rather short, lamina 

 linear, point rather blunt, entire, recurved, the basal appendage linear, curved 

 ■and strongly penicillate. Column stained with purple, wings with rather 

 prominent lower lobes.

(After G. Caley, a diligent collector of N.S.W. plants.) 



Sepals and petals all linear, the dorsal sepal erect, the lateral sepals and petals 

 spreading or reflexed (but the position apparently reversed by the resupination of 

 ■the flower on the ovary). Labellum articulate at the base of the column or at 

 the end of its basal projection and moveable (irritable), with a linear incurved 

 -claw, the lamina ovate or oblong, peltate, convex, entire, shorter below than 

 :above its insertion, the surface smooth or tuberculate. Column elongated, 

 sometimes produced at the base into a linear projection, very broadly 2-winged 

 in its whole length. Anther erect, not mucronate, the 2 cells distinct and nearly 

 equally 2-valved. Pollen-masses granular. — Terrestrial glabrous herbs, with 

 small underground tubers. Leaf linear lanceolate or oblong, solitary- at the 

 ibase of the stem which has also occasionally a small empty bract at or below the 

 middle. Flowers 1 to 8 or rarely 4, shortly pedicellate, the subtending bracts 

 acute. Ovary usually recurved, reversing the flower. 



The genus is limited to Australia. Allied to Drakced, it is readily known by the large petal- 

 like wings of the column, forming a kind of pouch open or closed by the elastic motions of the 

 lid-like labellum.

1. C. major (greater), E. Br. Prod. 329; Benth. Fl. Austr. vi. 365. Leaf 

 radical, linear or narrow-lanceolate, 2 to 4in. long. Stem often above 1ft. high, 

 with a single closely appressed empty sheathing bract below the middle, and 1 to 

 4 red flowers on very short pedicels, the subtending bracts 2 to 4 lines long. 

 Dorsal sepal narrow-linear, rather thick, channelled, erect or incurved below the 

 middle, often fin. long ; lateral sepals narrow-linear, acuminate, reflexed (erect 



■ by the reversion of the flower) about 6 lines long ; petals still narrower and 



shorter, erect (with reference to the floral axis). Labellum affixed to the base of 



the column, the claw linear, flat, incurved, about 8 lines long ; lamina peltately 



attached, broadly ovate, fully 4 lines long and nearly as broad, shortly and 



broadly acuminate at each end, the upper surface smooth, the centre inflated and 



hollow, the cavity open on the under side. Column 4 to 5 lines long, bordered 



■ • on each side from the base to the anther with a petal-like coloured wing about

2. C. minor (smaller), R. Br. Prod. 329 ; Benth. Fl. AuHr. vi. 366. Leaf
