■ or empty scales lanceolate, erect or slightly spreading, acuminate, under lin. long 

 in the typical form, and none usually so long as the bract subtending the 

 terminal pedicel, more leaf-like and longer in some varieties. Galea IJ to above 

 l^in. long, curved but not abruptly so, the petals as well as the sepal tapering 

 into fine points ; lower lip euneate at the base, the lobes lanceolate, separated by 

 a sinus much narrower than in P. grandijlora, and almost acute, tapering 

 into long filiform points embracing the galea. Labellum more or less lanceolate 

 and tapering towards the end into a long or short point ; thel)asal appendage 

 "linear, curved, penicillat'e at the end. Column-wings with a small erect acute 

 lobe at the front angle, the lower lobe oblong and obtuse. — Lindl. Gen. and Sp.

8. P. obtusa (blunt), E. Br. Prod. 327 ; Benth. Fl. Austr. vi. 360. Stems 

 -slender, 1 -flowered, usually about Gin. high, without any radical leaves at the 

 time of flowering but often from a separate branch of the rhizome a rosette of 

 ■ovate 5-nerved leaves like those of P.concinna. Stem-leaves or bracts lanceolate, 

 acuminate, ^ to fin. long, not different from the uppermost bract which subtends 

 Jthe terminal pedicel, the lower ones reduced to sheathing scales. Galea iftCurved, 

 f to near lin. long, besides the point which varies from 2 to 6 lines ; lower lip with 

 the entire part very broadly euneate, almost truncate, 4 to 5 lines long, the lobes 

 ■very divaricate separated by a broad sinus notched in the centre, tapering into 

 long subulate antenna-like points embracing the galea, Labellum the length of 

 the column, oblong-linear, equally broad throughout and very obtuse, the basal 

 ■appendage linear, curved, penicillate, the tuft consisting usually of 2 eilliate seta3. 

 Column-wings with a prominent tooth or linear upper lobe at the front angle, the 

 lower lobe oblong, the stigma very prominent. — Lindl. Gen. and Sp. Orch. 389 ;

'9. P. parviflora (small flowered), R. Br. Prod. 327 ; Benth. Fl. Aicstr. vi. 

 861. Leaves in radical rosettes appearing at a different time of the year from 

 the flowering-stem or if contemporaneous in a tuft by the side of it, ovate, under 

 ■|in. and often only Jin. long on a rather long petiole; Scape slender, 4 to Sin. 

 high, with 2 or 3 empty bracts or small sheathing leaves and a raceme of 2 to 5 

 small flowers. Galea much incurved, scarcely 5 lines long, very acute or 

 -shortly acuminate, lower lip euneate, the entire part about 2 lines long, the lobes 

 much incurved, the inner margin involute at the base, tapering into points 

 Tariable in length but always shorter than the galea. Labellum very short, 

 -obtuse but entire, the basal appendage short and slender, terminating in a tuft 

 -of 3 setse. Column slender, the wing from a narrow base very prominent, 

 with a narrow point at the upper outer angle, and a broad lower lobe. — Lindl.

 Leaves in a radical rosette at the base of the flowering stem sometimes but not 

 -usually withering away at the time of the flowering, ovate, very shortly petiolate 

 or almost sessile, mostly i to fin. long. Stem 4 to 8in. high, with 1 to 5 empty 

 sheathing bracts, besides those subtending the pedicels, all obtuse or the upper
