1. P. Banksii, R. Br. ex A. Cunn. in Bot. Mag. t. 3172.—Tall, 
slender, leafy, grassy, 6-18in. high. Lower leaves reduced to 
scarious sheathing scales; cauline numerous, sheathing the whole 
stem, usually overtopping the flower but often shorter than it, 
3-14in. long, +-4in. broad, narrow linear-lanceolate, acuminate, 
pale-green. Flower solitary, large, 2-3 in. long including the tails 
to the lateral sepals, green, often streaked with red or reddish- 
brown. Galea erect at the base and then curved forwards; upper 
sepal produced into a long caudate often filiform point; petals also 
caudate-acuminate or shortly filiform, but always much shorter 
than the upper sepal. Lower lip with the entire part broadly 
cuneate, the free lobes gradually narrowed into long filiform erect 
tails 1-2in. long. Lip narrow linear-oblong, obtuse, its tip slightly 
exserted ; basal appendage curved, repeatedly divided and penicil- 
late at the tip. Column slender, more than half the length of the 
galea, upper lobe of wings with an erect subulate tooth at the outer 
angle; lower lobe narrow-oblong, obtuse.—A. Cunn. Precur. n. 313;

NortH AND SoutH Isnanps, STEWART IsLaAND, CHATHAM IsLANDS: Abund- 
ant in shaded places from the North Cape southwards. Sea-level to 3500 ft. 
October—November. 
The most widely spread of the New Zealand species. It varies much in 
size and degree of robustness, the size of the flower, and in the length of the 
filiform tails to the sepals and petals, &c. Mr. Colenso has made no less than 
5 species based upon what appear to me to be exceedingly slight and inconstant 
differences. After a careful study of his descriptions and specimens I must 
confess my inability to distinguish any of them, even as varieties. 
2. P. australis, Hook. f. Fl. Nov. Zel. i. 248.— Habit of 
P. Banksw but shorter, 4-10 in. high, rarely more. Leaves shorter 
and broader, seldom overtopping the flower, }—-%in. broad, linear- 
lanceolate, acute or acuminate. Flower small, 3-14 in. long, in- 
cluding the points of the sepals. Galea much as in P. Banksv, 
but the upper sepal and petals are not produced into filiform points. 
Lower lip with the free lobes narrowed into short subulate erect 
points not exceeding the galea in length. Lip and column as in 
P. Banksw.—P. Banksii var. b, Hook. f. Handb. N.Z. Fl. 268.
