This is a very handsome species, but, like its congeners, very variable in size: alpine specimens are almost 
stemless, with three to four sessile radical leaves, a short scape, and a flower hardly exserted beyond them; more 
generally it is an erect plant, a span high, very like the P. micromega, but with larger, more reticulated radical 
leaves and flowers, whose perianth (3—1 inch long) is erect at the base, and then curved horizontally, with the tips 
of the petals and upper sepal bent downwards. 
6. Pterostylis Zru//ifolia, Hook. fil.; pusilla, caule gracili, foliis radicalibus longe petiolatis late 
ovato-cordatis acutis, scapo 2-3-bracteato, perianthio basi erecto dein decurvo, sepalis lateralibus apice 
filiformibus supremo petalisque acuminatis, labello lineari, appendice apice penicillata. 
Has. Northern Island. Bay of Islands, Zdgerley, Colenso, etc. Auckland, Sinclair. 
A very common slender species, 4-6 inches high. Radical leaves broadly ovate, cordate, triangular or the 
form of a trowel, 2 inch long, on slender petioles 4-1 inch long. Scape with two or three small bracts. Perianth 
+ inch long, erect below, upper half horizontal or decurved; lateral sepals with filiform erect points, the other 
sepal and petals acuminate; Zip linear, with a short subulate blunt appendix, villous at the point. 
7. Pterostylis puberula, Hook. fil.; pusilla, foliis radicalibus confertis breve petiolatis ovatis acutis 
acuminatisve, scapo glanduloso puberulo 3-bracteato, perianthio basi erecto dein curvo, sepalis lateralibus 
apice filiformibus supremo petalisque subacutis, labello lineari-oblongo, appendice subulata infra apicem 
subramosa. 
Has. Northern Island. Auckland, Sinclair. 
I have several good specimens of this peculiar little species, which is more robust than P. trudlifolius, with 
glandular scape, and crowded ovate acute radical leaves on short petioles. Root of small tubers, attached to long 
fibres. Leaves 4 inch long, with the petioles. Scape 2-3 inches high, with three sheathing bracts. Perianth 
3 inch long; lateral sepals with filiform apices, upper and petals broad and blunt at the tip; lip linear-oblong, broader 
and more membranous than in the previous species, with a delicate curved appendix, irregularly but sparingly 
fimbriate or branched towards the tip. 
8. Pterostylis sguamata, Br.; foliis radicalibus confertis ovato-lanceolatis acuminatis, scapo bracteato, 
perianthio erecto, sepalis lateralibus brevibus linearibus obtusis supremo galeato acuto, petalis anguste 
lineari-subulatis, columna apice utringue late alata, alis decurvis margine superiore cornutis. Br. Prodr.

Has. Northern Island. Auckland, Sinclair. 
A very singular and beautiful plant, a native of Tasmania, easily recognized by the filiform lip, fringed with 
feathery yellow hairs, and thickened into a round purple glandular head, like that of a nail. Plant 5—8 inches 
high. Leaves sessile, numerous, crowded, radical, ovato-lanceolate, acuminate, 4—1 inch long.» Scape with sheathing 
bracts. Perianth erect, £ inch long; upper sepal hooded, acuminate, the narrow petals cohering to its margin; 
lateral sepals deflexed, linear, blunt, shorter than the upper. Zip with a curved, villous (sometimes blunt, glabrous) 
appendix. Column with two broad projecting hooked fimbriated wings at the tip, which have a long erect subulate 
horn, 
Gen. XV. NEMATOCERAS, Hook. fil.
