 not clubbed, lanceolate, deflexed or spreading. Labellum on a rather long and movable 

 claw ; about 9 mm. long (extended) and 10 mm. wide ; crescent -shaped in the typical 

 form with a broad apical extension ; the apex short, maroon, .recurved ; anterior margin 

 fringed with narrow short denticulations ; lamina behind the tip greenish -ye How, some- 

 times with conspicuous divergent veins ; calli on long stalks with fleshy heads, maroon- 

 colored, in 4 obscure rows along the centre but not extending to the apical portion. 

 Column about 10 mm. long, much incurved, broadly winged in upper two-thirds ; 2 

 yellow sessile calli at the base. 



Caroona Hill, near Iron Knob ; Crystal Brook. Aug. -Sept. 



6. C. reticulata (netted, referring to the dark red veins on labellum), Fitzg. Slender, 

 hairy, 10-30 cm. high. Leaf very hairy, generally linear or narrow-lanceolate, channelled, 

 about 4-8 cm. long. Flowers large, usually single, rarely 2, prevailing tints yellowish- 

 green and crimson, sometimes wholly crimson. Sepals yellowish -green with red central 

 stripe, clavate, of equal length. Dorsal sepal erect, incurved, about 2-7 cm. long, dilated 

 in basal half, thereafter contracted into a filamentous clavate point ; lateral ones similar, 

 but rigidly spreading. Petals lanceolate, usually darker, shorter, and narrower, not 

 clubbed, spreading, with crimson stripe, gradually narrowing from the base to a fine 

 point. Labellum on a distinct movable claw ; crimson or crimson and yellow, ovate, 

 12-13 mm. long; lower half erect with dentate margins; recurved part rather acute, only 

 slightly denticulate ; calli fleshy, crimson, of the golf -stick type, hardly extending beyond 

 the bend ; lamina smooth at the tip, generally with dark crimson veins, the latter some- 

 times inconspicuous. Column retracted at the base, thereafter erect and incurved ; 

 9-10 mm. high ; widely winged above, more narrowly below ; 2 sessile yellow calli at the 

 base. Anther with straight sharp point.

7. C. Patersonii (after Col. Wm. Paterson, Lt. -Governor of New South Wales and 

 Tasmania), R. Br. A hairy species 20-30 cm. high. Leaf hairy, oblong to linear-lanceo- 

 late, sometimes quite short but often exceeding 15 cm. long. Flowers large, usually 

 solitary, occasionally 2 or 3, generally white or creamy with dark points on perianth- 

 segments and labellum, more rarely crimson or yellow, sometimes yellowish -green and 

 brown, often 10-15 cm. in diameter. Perianth-segments all spreading, except dorsal 

 sepal, with points dark and glandular -hairy, but not clavate. Dorsal sepal erect or 

 incurved over the column, the portion behind the column dilated, thereafter produced 

 into a long tentacular point, usually 4^-6 cm. long ; lateral sepals similar but spreading 

 and drooping, rather longer, with a wider and longer dilated portion. Petals shorter 

 than dorsal sepal, 4-5J cm. long gradually tapering to fine points. Labellum 1^-2 cm. 

 long (extended), usually with purple or crimson tip and calli ; ovate -lanceolate on a short 

 claw ; undivided ; the basal half commonly light-colored, erect, with acutely toothed 

 margins, anterior portion recurved, generally purple or crimson, the margins bluntly 

 toothed or serrate with acute tip ; calli of lamina rarely extending beyond the bend, 

 linear-golf-stick in the type, in 4-6 rows. Column incurved, about 12 mm. long ; winged 

 narrowly in lower part, widely above ; 2 yellow sessile calli at the base. Anther pointed. 



N.P. Widely distributed over the State (including Kangaroo Island) but not numerous ; 

 reported from all the other States. Sept. -Oct. 



8. C. dilatata (widened, referring to the lateral expansion of the labellum), R. Br. (PI. 8, ii.) 

 Often moderately robust, 15-45 cm. high, hairy. Leaf very hairy, oblong to elliptical, 

 lanceolate, often rather wide, 5-12 cm. long. Flower solitary, large, often 10 cm. in 

 diameter, prevailing tints green, yellow, and maroon. Perianth-segments all spreading 

 except dorsal sepal, yellowish -green with red central stripe ; sepals clavate, subequal ; 

 petals narrower and shorter, not clavate. Dorsal sepal erect, lower-third dilated, there- 

 after contracted into a clubbed filiform point, about 5-2 cm. long ; lateral sepals similar, 

 the basal part deflexed, the points thereafter spreading and sometimes crossed. Petals 

 falco -lanceolate gradually tapering into fine points, about 3 cm. long. Labellum (figs. 

 5, 6) maroon green and yellowish-white, tremulous on a movable claw, 3-lobed, somewhat 

 ovate, about 2\ cm. (including the claw) ; recurved near the middle ; the lateral lobes? 

 green, erect, their side margins entire, their anterior margins deeply combed or fringed ; 

 middle lobe recurved, widely lanceolate, margins toothed or serrate with maroon acute 

 tip ; calli maroon, golf-stick type, in 4 rows hardly extending beyond the bend, those 

 near the claw large, thick, and fleshy, the others small and linear. Column (figs. 7, 8) 

 much incurved, about 15 mm. long, widely winged, especially in the upper part ; 2 yellow 

 sessile calli at the base. Anther with well developed sharp point. 



N.P. Widely and plentifully distributed throughout the State, reaching at least as 

 far north as Burra ; also New South Wales ; Victoria; Tasmania; and Western Australia.
