rows. Column erect, 6-7 mm. long, pubescent on the back, moderately winged through- 

 out. Anther with a very long point. Pollinia 4, lamellate, a pair of deeply bilobed 

 " butterfly " masses in each cell. 



N.P. and other parts of Mount Lofty Range ; Beetaloo ; Angaston ; Port Lincoln ; 

 Yorke and Eyre Peninsulas ; Inman Valley ; Yeelanna ; Goolwa ; Millicent ; Kangaroo 

 Island; also all other States. Sept. -Oct. 



13. C. carnea (flesh-colored), R. Br. Very slender, 8-20 cm. high. Leaf hairy, narrow- 

 linear often as long as the scape. Flowers 1-3, pink, more rarely white. Perianth- 

 segments a dusky-green, with glandular-hairs and pink stripes on the outside, pink and 

 glabrous within ; tips generally acute, but sometimes blunt. Dorsal sepal erect or 

 slightly incurved, linear, 11-14 mm. long ; lateral sepals free, spreading, generally longer 

 than the dorsal sepal, 11-17 mm., lanceolate or falco-lanceolate. Petals narrower than 

 the sepals, but about the same length, spreading, falco-lanceolate ; sometimes, especially 

 in the smaller forms of the species, all the segments of the perianth equal. Labellum 

 sessile, 3 -partite, erect at base, recurved beyond the middle ; lateral lobes broad, erect, 

 prominent with rounded anterior border and entire margins ; middle lobe lanceolate, 

 more or less dentate or fringed with a few calli ; lamina with two rows of stalked clubbed 

 calli (sometimes larger and in 4 rows at the base), not extending beyond the bend, with 

 interrupted transverse red linear bands, about 6 mm. long. Column about 6 mm. long, 

 incurved, rather narrowly winged, with transverse linear red markings anteriorly. Anther 

 with rather a long point. 



N.P. Widely distributed ; reported as far north as Beetaloo and Wirrabara Forest ; 

 south from Millicent and Mount Gambier ; west from Yorke and Eyre Peninsulas and 

 Kangaroo Island ; also from all other States. Sept. -Oct. 



14. C. congesta (crowded, referring to the calli), R. Br. Slender, slightly hairy, 15-60 cm. 

 high. Leaf linear, 7-12 cm. long, very slightly hairy. Flowers pink, 1-3, on slender 

 pedicels. Perianth-segments covered with glandular hairs on the outside, all spreading 

 except dorsal sepal. Dorsal sepal shorter than the other segments, about 12 mm., in- 

 curved over column, lanceolate ; lateral sepals about 18 mm. long, elliptical-lanceolate 

 Petals about 14 mm. long, falcate. Labellum pink, about 9 mm. (extended), on a rather 

 long and narrow claw ; basal-half erect against the column, thereafter gradually curved 

 forward ; very distinctly 3-lobed ; lateral lobes falcate, acute, reaching well beyond 

 the middle of labellum, margins entire ; middle lobe oblong-lanceolate, much elongated 

 and very narrow, margins entire. Calli dark-crimson, imbricate, completely covering 

 middle of labellum to the very tip ; at first placed longitudinally in 2 rather obscure rows, 

 the 2 nearest the claw being stalked, the others large sessile, flat-topped, more or less 

 oblong. Column about 8 mm. long, incurved, with rather wide wings, especially in the 

 upper part, blotched with pink markings. Anther pointed.

15. C. testacea (brick-red), R. Br. Slender, sparsely hairy, 15-45 cm. high. Leaf 

 narrow-linear, very slightly hairy, 6-12 cm. long. Flowers dark and glandular on the 

 outside, white inside, 1-5 in a raceme, on slender pedicels ; buds characteristic, bluntly 

 falcate in shape, covered with dark glandular hairs. Perianth-segments generally dark 

 reddish-brown (except towards the base) on outside, white or light-colored within ; sub- 

 equal ; all spreading except the dorsal sepal. Dorsal sepal erect incurved, about 10 cm. 

 long, concave, acute, contracted at the base ; lateral sepals slightly longer than other 

 segments, elliptic-lanceolate. Petals falco-lanceolate. Labellum about 7 mm. long 

 (extended and including claw), on a movable claw, the basal portion erect against the 

 column, recurved forward about the middle ; margins entire except towards the triangular 

 tip, the edges of which are shortly and sparsely denticulate ; labellum obscurely 

 3-lobed, the lateral lobes being ill-defined ; calli of the lamina in 4 rows reaching almost 

 to the extreme tip, where the rows are not so evident, clubbed, the stalks shorter towards 

 the tip. Column 7-8 mm. long, incurved, widely winged, especially in upper part.

16. C. eoerulea (sky-blue), R. Br. Slender, sparsely hairy, with the habit of C. carnea, 

 8-15 cm. high. Leaf linear-lanceolate, only slightly hairy. Flower solitary, bright j 

 blue, very rarely white. Perianth-segments lighter -colored externally and beset with 

 minute dark-blue glandular hairs, all contracted at base. Dorsal sepal about 11 mm. 

 long, narrower than lateral sepals, erect, concave, 3-nerved, slightly incurved, rather 

 blunt ; lateral sepals about 13 mm. long, elliptic-lanceolate, acute, spreading, 5-nerved. 

 Petals about as long as lateral sepals, but rather narrower, spreading, 5-nerved. Labellum 

 (when extended) about same length as column ; on a short claw ; distinctly 3-lobed ; 

 lateral lobes erect and embracing the column, broad and rounded with entire margins ; 

 middle lobe much recurved, narrow, cuneate, hardly acute, with entire margins ; lamina 

 with transverse linear dark-blue bands on a lighter ground ; calli linear, yellow, clubbed, 

 in 2 rows extending to the extreme tip. Column about 7| mm. long, much incurved, 

 moderately winged throughout. Anther with a distinct point.
