cohering at the base, usually 2-dentate, all brown-greeu ; side pair narrow, 

 similar to the outer segments. Labellum recurved, chiefly towards the apex, 

 broad below (except at the base), narrow above, acute ; central plate prominent, 

 swollen, extending nearly to the end. Lateral lobe of the column rather shorter 

 than the anther, broad, rounded or obscurely 2-lobed above, and with a large, 

 but not prominent, gland towards the base of the anterior margin. P fuscum 

 and P. alpinum., Hook. 



Mount Wellington summit. Cascades (Hobart), Kingston, near Strahan, 

 George's Bay, Rocky Cape, &c. ; also in Queensland, New South "Wales, Victoria, 

 and South Australia. PI. Oct.-Feb. 



7. P. AUCB.^'Ri, Hook. Stem slender, 6-9 inches high. Leaf reduced to a bract 

 close under the inflorescence. Flowers few, in a rather loose terminal spike. 

 Outer segments dark red-brown, about J inch long, the one below the column 

 (together with the side pair) ciliate on the margin, the pair about the labellum 

 linear, acate, but dilated towards the base. Labellum narrow-oblong, fringed 

 with long hairs, supported on a short slender stalk, irritable. Lateral lobe of 

 the column rather long, bifid.

8. P. INTBICATDM, C Stuuvt. A plant of similar habit and structure to the 

 last. . Flowers pale. Outer segments about 2 lines long, the upper pair linear, 

 acute, broad near the base, but not dilated. Labellum broadly obovate, fringed 

 with shorter hairs than in the last, but similarly supported. 



Southport; also Victoria PI. Dec. -Jan. 



9. P. DESPECTANS, Hook. Stem about 6-9 inches high, with a bract-like leaf 

 about an inch below the inflorescence. Flowers dark brown-red, many in a rather 

 dense terminal spike. Upper pair of segments tipped with glands, linear, 

 acute, about 2 lines long ; the lowest segment short, broad, and very concave, 

 acute ; side pair very short, broad, acute. Labellum narrow-oblong, acute, 

 about 1 line long, concave-convex, supported on a short slender stalk, irritable. 

 Lateral lobes of the column with a broad base and an acute apex adnate to the 

 whole length of the column.

 Bruni Island, George's Bay, &o. ; also South Australia and Victoria. PI. Peb. 



10. P. NiGEiCANS, R. Br. Similar to the last, only rather smaller. Flowers 

 very dark and small, in a small, dense, terminal spike. Upper pair of segments 

 tipped with glands, about 2 lines long, broadly lanceolate, acute ; the lowest 

 segment much shorter, broad, and concave ; side pair of segments rather longer 

 than the upper pair, broad, acute. Labellum ovate, acute, about 1 line long, 

 supported on a slender stalk, irritable. Lateral lobes of the column compara- 

 tively very large, adnate throughout the entire length of the column, tapering 

 into a bifid apex.

 been found in New South Wales, South Australia, Victoria, and Queensland.

11. P. EUFUM, R. Br. Size and habit similar to P. despectans. Flowers dark 

 red-brown, very small, about 1 line long. Upper pair of segments lanceolate, 

 probably, like P. despectans and P. nigricans, tipped with glands, but hardly 

 discernible, except when young and fresh ; lowest segment ovate, concave, acute. 

 Labellum narrow-lanceolate, recurved, on a slender stalk, irritable. Lateral 

 lobes of the column very stort, bifid. P. nudum. Hook.
