1574 CXXVII. OECHIDE^. {Pterostylis- 



Seot. II. CatOChilus. — Lower lip reflexed from the base or recurved from the middle,, 

 the Inbes short and narrow. Labellum-nppendage entire and obtuse, sometimes almost obsolete. 



Flowers several, under Jin. long. 



Leaves in a radical rosette, persistent or fading away before 

 flowering, those of the stem reduced to scarious sheaths. 



Sepals all obtuse, the lower lip shortly 2-lobed 10. P. mutica. 



Sepals with short or rarely long fine points, the lower \\^ deeply 



2-lobed 11. P. rufa. 



Stems leafy without a radical rosette. 

 Leaves linear or li«ear-lanceolate. Column-wings neat-ly square . . 12. P. longifolia. 



Only one specimen obtained, perhaps only an abnormal growth of some 

 of the above 13. P. depaiqyerata. 



1. P. ophioglossa (snake's tongue), R. Br. Prod. 326 ; Benth. Fl. Austr.. 

 vi. 354. Leaves in a radical rosette, shortly petiolate, ovate or broadly oblong,, 

 obtuse or mucronulate, f to l^in. long, elegantly veined, the transverse veinlets 

 usually uniting in 2 lateral nerves on each side of the midrib. Scape l-flowered,„ 

 rarely above Gin. high, without any or vifith a single empty bract near the base, 

 the terminal pedicel subtended by a rather broad, very acute bract of 4 to 8- 

 lines. Galea incurved, acuminate, fully IJin. long, rather broad, striate ; lower 

 lip erect, broadly cuneate, deeply 2-lobed, at least fin. long besides the long- 

 subulate points which embrace the galea. Labellum-claw flat and thin, about 

 1 line long, lamina oblong-linear, ending in 2 narrow lobes of about 1 line, the- 

 basal appendage linear subulate, curved upwards with a terminal tuft of setae. 

 Column nearly as long as the labellum, reflexed lobe of the wings oblong and. 

 obtuse, the erect lobe smaller lanceolate and acute. — Lindl. Gen. and Sp. Orch..

Hab.: Port Curtis, R. Brown; Brisbane Eiver, Moreton Bay, F. v. Mueller, Filzalan, Bailey ;- 

 common in southern localities. 



2. P. concinna (neat), R.Br. Prod. 326; Bcnth. Fl. Aiistr. vi. 355^ Nearly- 

 allied to P. ophiorjlossa, but a smaller plant. Leaves radical, under lin. long, 

 ovate or broadly oblong, the petiole usually longer than in P. ophio//losm, the- 

 venation the same. Scape 1-flowered, usually with an empty bract at or below 

 the middle, besides the sheathing bract at the base of the terminal pedicel. 

 Galea broader and more incurved than in P. opiiioglossa, and under lin. long ;: 

 lower lip also broader and shorter, the lobes more divaricate, the long points fine- 

 or slightly clavate. Labellum rather shorter than the column, broader than in 

 P. ophioglossa, the terminal lobes or teeth very short and broad. Column-wings 

 with the erect lobe acutely acuminate and rather long. — Lindl. Gen. and Sp. 

 Orch. 391 ; Hook. Journ. Bot. i. 274, t. 136 ; Eeichb. f. Beitr. 34 ; P. acuminata,.

Hab.: Southern localities. 



The plate in Bot. Mag. t. 3400 appears to me rather to represent one of the long-flowered 

 forms of P. mrta. — Benth. 



3. P. curta (curtailed), 7?. Br. Prod. 326 ; Benth. Fl. Austr. vi. 355. Leaves 

 in a radical rosette, usually on long petioles, ovate or broadly elliptical, 5 to 

 9-nerved, from under lin. to l|in. long. Scapes 1-flowered, usually about 6in. 

 high, with 1, 2 or 3 4ong loosely sheathing empty bracts besides the one 

 subtending the terminal pedicel. Galea erect, about IJin. long, acute but not 

 acuminate. Lower lip cuneate, with 2 broadly lanceolate lobes, not so long as 

 the galea and only shortly acuminate in the typical form. Labellum linear,, 

 obtuse and entire, rather longer than the column, the surface papillose, the basal 

 appendage linear curved and penicillate. Column 7 to 8 lines long, with the 

 basal projection rather long ; wings with the lower lobe oblong and obtuse, tha
