Pterostylis.| ORCHIDE®. 681 
few, large, 14-34 in. long, ?-1 in. broad, oblong-ovate or elliptic-ob- 
long to oblong-lanceolate, acute, narrowed into a short broad petiole 
or almost sessile, thin and membranous, veins reticulated; cauline 
leaves 2 or 3, almost as long but narrower, lanceolate or oblong- 
lanceolate, acute or acuminate, flat, spreading, sheathing at the 
base. Flowers large, solitary or very rarely two, 1-11in. long. 
Galea bent forwards from above the base and then curved sharply 
downwards so that the point often reaches the ovary; upper sepal 
produced into a long acuminate point; petals much shorter, falcate, 
acuminate. Lower lip with the entire part broadly cuneate, the 
free lobes gradually narrowed into long filiform points embracing 
the galea and sometimes 1$in. long. Lip narrow-linear, obtuse; 
basal appendage short, curved, penicillate. Column slender, not 
half the length of the galea; wings with a short upper lobe 
bearing an erect subulate tooth at the outer angle, lower lobe very 
long, linear-oblong, obtuse.

Very close to P. micromega, but stouter, with much larger radical and 
-cauline leaves, and with the flower very conspicuously decurved. 
6. P. foliata, Hook. f. Fl. Nov. Zel. i. 249.—Rather stout, 
glabrous, 2-8in. high. Lower leaves 2-5, subrosulate, sessile or 
petioled, 1-1$in. long, elliptic-oblong to linear-oblong, obtuse or 
acute, veins reticulated; cauline leaves reduced to 1 or 2 large 
sheathing erect lanceolate bracts 3-lin. long. Flower solitary, 
erect, 3in. long. Galea erect at the base, curved forwards at the 
tip; upper sepal acute or acuminate ; petals falcate, obtuse or sub- 
acute. Lower lip with the entire part short, broadly cuneate, the 
free lobes gradually narrowed into rather short filiform points 
embracing the galea but not much exceeding it. Lip linear-oblong, 
flat, obtuse; basal appendage short, curved, penicillate at the tip. 
Column not half the length of the galea, upper lobe of wing with a 
subulate tooth ; lower lobe linear-oblong, obtuse.—Handb. N.Z. Fl.

Differs from P. micromega in the stouter habit, larger more reticulate and 
often decidedly rosulate radical leaves, cauline leaves reduced to sheathing bracts, 
smalier flowers with shorter points to the lateral sepals, and broader shorter lip.
