subulate or shortly filiform erect points almost equalling the galea. Lip 
and column as in P. Banksii.—Handb. N.Z. Fl. (1864) 268; Cheesem. 
Man, N.Z. Fl. (1906) 680. 
Var. rubricaulis H. B. Matthews MS. n. var.—Very close to the type, but 
stems red, leaves usually 3 only, seldom 4, Flowers larger and broader, sometimes 
1tin. long. Lateral sepals considerably longer. 
Norru anp Sourn Istanps, Srewart Istanp : Not uncommon in shaded places 
in lowland districts from the North Cape southwards. September—November. 
Differs from P. Banksii in the smaller size, narrower leaves, and smaller flower 
with very,short tails to the sepals. = 
4. P. micromega Hook. f. Fl. Nov. Zel. i (1853) 248.—Slender, glabrous, 
4-12in. high. Lower leaves 4-1} in. long, }-}in. broad, ovate-oblong to 
linear-oblong or lanceolate, obtuse or acute, sessile or petiolate ; cauline 
2-5, smaller and narrower, sessile, flat, sheathing at the base, acute or 
actuninate. Flower large, solitary, erect, 3-Idin. long. Galea erect at the 
base, then incurved, tip horizontal or nearly so; upper sepal narrow, 
acuminate ; petals slightly shorter, broad, falcate, acuminate. Lower lip 
with the entire part cuneate, the free lobes very gradually narrowed imto 
long filiform points embracing the galea, often quite lin. long. Lip 
narrow-linear, its tip exserted; basal appendage curved, penicillate. 
Column about 4 as long as the galea, upper lobe of wing with an erect 
subulate tooth, lower lobe oblong, obtuse——Handb. N.Z. Fl. (1864) 268 ;

Best known by the slender habit, usually few radical leaves, numerous rather 
small flat cauline leaves, and large flower projecting outwards but not decurved at the 
tip. 
5. P. areolata Petrie in Trans. N.Z. Inst. | (1918) 210.—Slender, glab- 
rous, 4-6in. high. Lower leaves not seen. Cauline leaves 2-3, 15-2 in. 
long, 4-$in. broad, oblong-lanceolate or elliptic-lanceolate, acute or sub- 
acute, thin, flat, sheathing at the base, finely reticulately veined. Flower 
rather large, solitary, erect, 14-14 in. long, green streaked with reddish- 
brown. Galea erect at the base for more than 4 its length, then suddenly 
curved forwards ; upper sepal terminating in a rather long but not filiform 
tip. Lower lip with the entire portion obcuneate, the free lobes gradually 
narrowed ihto long wide-spreading filiform points almost reaching the top 
of the galea. Column more than $ as long as the galea. Lip narrow- 
linear, its tip exserted.

Cockayne! Canterbury-——-Waimakariri Valley, at Bealey, 2500 ft., 7. Kirk! 
This is a somewhat critical species, which can hardly be considered as well 
established until more material has been obtained. Only 2 flowering specimens have 
been seen. ; 
6. P. Oliveri Petrie in Trans. N.Z. Inst. xxvi (1894) 270.—Stout or 
slender, leafy, glabrous, 6-12 in. high. Lower leaves few, large, 14-34 in.
