ones acute. Flowers 5 to 10, in a slightly spiral spike. Galea broad, much 

 incurved, obtuse, about 3-| lines long ; lower lip little more than 2 lines long and 

 at least as broad, concave, reflexed, with 2 short broad obtuse lobes. Labellum 

 on a rather long flat claw, broad, very obtuse, scarcely 1^ lines long, the basal 

 lobe or appendage nearly as broad at the base, narrow, thick, obtuse and entire 

 or eniarginate at the end. Column reaching to the end of the galea ; the wings- 

 broad, without any upper lobe or tooth, the lower lobe broad and obtuse. — Lindl.

11. P. rufa (reddish), 11. Br. Prod. 827; Benth. Fl. Austr. vi. 863. Leaves 

 in a radical rosette at the base of the stem, but most frequently withering away 

 before the flowering, ovate, obtuse or acute, | to lin. long. Stem 6 to lOin. 

 high, with 2 to 4 loosely sheathing rather scarious empty bracts usually acute, 

 besides the bracts subtending the pedicels. Flowers usually 3 or 4 in a short 

 raceme. Galea about 5 lines long, hood-shaped, produced in front into a fine 

 point 10 lines long in the typical form, very much longer in some varieties ;. 

 lower lip on a rather long basal projection of the column, reflexed from it,. 

 broadly cuneate, 3 to 4 lines long without the points, divided to the middle into 

 broadly lanceolate lobes ending in fine points, varying in length like that of the 

 galea. Labellum on a short claw, ovate-oblong or narrow, concave or with, 

 involute margins, scarcely If lines long, obtuse, bordered by few or many- 

 marginal cilia rarely entirely wanting, usually 1 long one on each side near the 

 base, the basal appendage short, thick, entire, rugose, often ciliate. Column, 

 reaching to the end of the galea, the wings broad and nearly square, with a small 

 point at the upper front angle, the lower angle or short broad lobe often ciliate, 

 the middle part of the column narrowly winged. — Lindl. Gen. and Sp. Orch. 890;

 Pf. 2. 



Hab.: Brisbane to Koekhampton near the coast and inland. 



Tbe species varies much in stature, in the persistence of the radical leaves, in the size of the 

 flowers, and especially in the length of the sepal-points. 



12. P. longifolia (leaves long), B. Br. Prod. 327 ; Benth. Fl. Austr. vi. 364. 

 Stems rather slender, but often 1ft. high or rather more, without any radical 

 rosette, the lower leaves reduced to short sheathing scales, those at and above- 

 the middle of the stem linear or linear-lanceolate, acute or acuminate, from 

 under 1 to above 2in. long, very shortly sheathing at the base. Flowers 3 to- 

 7 in a terminal raceme. Galea 5 to 7 lines, more or less incurved above the 

 ovary and again abruptly curved towards the end, acute or with a short point in 

 front ; lower lip reflexed, 4 to 5 lines long, oblong, divided usually to about half 

 its length into 2 narrow-lanceolate lobes. Labellum on a very short claw, oblong, 

 about 3 lines long, more or less papillose on the surface, with a short obtuse or 

 2-toothed papillose process at the end, the basal appendage very short, obtuse 

 and usually erect. Column-wings very broad, nearly square or slightly hatchet- 

 shaped, the margins ciliolate or entire. — Lindl. Gen. and Sp. Orch. 388 ; Hook. ' 

 f. Fl. Tasm. ii. 22, t. 117 ; Eeichb. f. Beitr. 40 ; Fitzg. A^ustr. Orch. i., Pt. 1. 



Hab.: Taylor's Range and other southern localities. 



The species varies much in the length and breadth of the leaf, in the size of the flowers, the 

 length of the lobes of the lower lip and the precise form of the labellum, especially of its 

 terminal appendage. 



13. P. depauperata (impoverished). Bail. Bat. Bull. iv. Tubers about 

 the size of a small pea, often at a distance of l|in. from the leaves. Leaves 

 radical, almost in a rosette, ovate-oblong, on conspicuous petioles, 6 or 8 lines-
