10. Pterostylis mutica (Br. Prodr. 328); foliis radicalibus confertis stellatis breve petiolatis ovatis, 
scapo bracteato multifloro, spica subspirali, floribus suberectis, perianthio inclinato v. horizontali, galea 
brevi lata obtusa, labio inferiore deflexo ovato obtuso indiviso v. breviter bifido, labello oblongo obtuso, 
appendice elongata apice lobata v. obtusa.—Jind/. 7. e. 390. (Gunn, 605, 900, 901.) (Tas. CXVII. B.) 
Has. Common in rich pastures, as well as in light sandy soil.—(Fl. Oct., Nov.) (v. v.) 
DisrarB. New South Wales and Victoria. 
A very variable and abundant species, from 3 to 10 inches high, robust or slender, few- or many-flowered, the 
flowers small, densely or loosely spiked, the spike straight or somewhat twisted.—Leaves all radical, numerous. 
Scape bracteate. Flowers suberect, 1-2 inch long.  Perianth inclined or horizontal. Galea short, broad, blunt, 
nearly straight, or incurved at the apex. Lower lip bent down, ovate, entire and blunt, or bifid at the apex. Za- 
bellum short, broad, with a long, stout, incurved appendix, that is simple or thickened at the apex, and there entire 
or lobed. Wing of column slightly ciliated at the lower margin, scarcely auricled.—PrATE CXVII. 4. Fig. 1, side, 
and 2, front view of lower lip and labellum; 3, side, and 4, front view of column :—all magnified. 
ll. Pterostylis rufa (Br. Prodr. 327); foliis radicalibus stellatis petiolatis ovato-oblongis acutis, 
scapo bracteato 3-5-floro, perianthio horizontali, galea lata abrupte longe acuminata, labio inferiore deflexo 
bifido lobis ovatis subulatis, labello obovato emarginato longe laxe piloso, appendice brevissima obtusa ciliata.

Var. a; foliis coztaneis, scapo laxe bracteato, floribus remotis majoribus pedicellatis. 
Var. 8; scapo florifero aphyllo, bracteis numerosis, spica densiore, floribus minoribus subsessilibus. 
Has. Port Sorrell, on dry sandy ridges near the beach, ArcAer.—(Fl. Nov.) 
DrsraIB. New South Wales. 
I have described two forms of this plant, both from Mr. Archer; of one, which agrees with authentic speci- 
mens of Brown's P. rufa, 1 have seen only a drawing: it has larger and longer-pedicelled flowers ; of the other I have 
examined three specimens from Mr. Archer: it has no leaves, more bracts on the scape, smaller and more sessile 
flowers. The species is intermediate in size and habit between P. mutica and P. squamata, having the numerous 
flowers of mutica and the bearded labellum of squamata : it is however extremely different from both.— Seapes 4-8 
inches high, leafless, or with ovate, oblong, stellate leaves at the base. Flowers reddish-yellow-green, 2 inch long. 
Perianth inclined or horizontal. Galea broad, abruptly acuminated, with a long point. Lower lip sharply bifid. 
Labellum coriaceous, small, broadly oblong, blunt, bearded with long hairs; appendix blunt, ciliated. Wings of 
column ciliated, hardly auricled.—PrATE CXVI. B. Fig. 1, front, and 2, side view of labellum ; 3, column :—aZ 
magnified. 
$ 3. Radical leaves none ; cauline none, or alternate, lanceolate. Scape one-flowered. Lower lip of perianth 
ascending. Labellum glabrous. 
- 12. Pterostylis przecox (Lindl. Gen. et Sp. Orch. 388); caule gracili folioso, foliis alternis lan- 
ceolatis, flore solitario erecto, labii inferioris erecti laciniis filiformibus galeam lente curvam superantibus, 
labelli lamina lineari glabra, appendice penicillata. (Gunn, 751.) 
Has. Circular Head, Gunn; Hobarton, J. D. H.—(Fl. May-July.) (v. v.) 
DisrarB. Victoria. 
A very slender species, 3-5 inches high, sometimes pubescent on the stem and flowers.— Leaves lanceolate, 
alternate, $ inch long. Flowers erect, about 1 inch long, including the ovary. Galea curved. Lower lip with its 
filiform lacinim longer than the galea. Labellum very variable in breadth, almost sessile or unguiculate.— Very 
nearly allied to the P. scabra of Swan River, which has a more slender labellum, rather clavate at the tip. It may 
be a form of the P. reffeza or revoluta.
