682 ORCHIDEH, [Pterostyls. 
oblong to oblong-ovate or elliptic-oblong, obtuse or subacute, thin 
and membranous, veins conspicuously reticulated ; cauline leaves 
wanting. Scape short; flower solitary, $-%in. long. Galea erect 
at the base, sharply curved forwards towards the tip; upper sepal 
acute or acuminate; petals broadly falcate, acute. Lower lip 
broadly cuneate, the free lobes narrowed into filiform points ex- 
ceeding the galea, sometimes recurved at the tips. Lip lanceolate, 
narrowed to a blunt point, rather thick, grooved, purplish ; basal 
appendage penicillate at the tip. Column barely half as long as the 
galea, upper lobe of wing with an erect subulate point ; lower lobe

So far as can be ascertained from the limited amount of material available, 
this is separated from P. foliata by the smaller size and proportionately larger 
leaves, the short scape, which wants the large sheathing bracts of P. foliata, 
the more sharply curved and more acute galea, and differently shaped lip. 
8. P. trullifolia, Hook. f. Fl. Nov. Zel. i. 249.—Stem slender, 
glabrous, 2-6in. high, seldom more. Radical leaves often wanting 
in flowering specimens or 1-4, in flowerless ones more numerous 
and subrosulate, petiolate; blade +4in. long, broadly ovate or 
orbicular-cordate or trowel-shaped, acute or obtuse; petiole as long 
or longer than the blade. Cauline leaves or bracts 3-5, flat, 
spreading, 4-lin. long, lanceolate or linear-lanceolate, acute or 
acuminate, the lower sometimes broader and petiolate. Flower 
solitary, 4-lin. long. Galea erect at the base and then gradually 
curved forwards; upper sepal lanceolate, acuminate; petals as 
broad, falcate, acuminate. Lower lip broadly cuneate, the lobes 
long and filiform, embracing the upper sepal and exceeding it. Lip. 
linear, glabrous, obtuse, its tip exserted; basal appendage linear, 
much curved, penicillate at the tip. Column less than half the 
length of the galea; wings with a small triangular upper lobe or 
tooth; lower lobe oblong, obtuse-——Handb. N.Z. Fil. 269. P.

9. P. puberula, Hook. f. Fl. Nov. Zel. i. 249.—Stem slender,. 
puberulous, especially below, 2-4in. high. Leaves all radical, 
crowded in a rosette at the base of the stem, small, shortly petiolate, 
4-4 in. including the petiole, ovate or ovate-cordate, acute; bracts 
on the stem above the leaves 2-4, sheathing, erect, lanceolate, 
acuminate. Flower solitary, erect, in. long. Galea erect, shortly 
and abruptly incurved towards the tip, the upper sepal acute, the 
petals as long or rather longer, obtuse. Lateral sepals united for 
nearly half their length into a narrow almost quadrangular lamina,
