Frasophyllum .] 
lanceolate, with a flat, glandular, adnate plate; claw long. Column short; 
lateral lobes broad, acuminate, deeply 2- or 3-toothed. Anther apiculatc.- 
Ovary linear. 
Northern Island: east coast, clay hills, Te Hawara, Port Nicholson, and Lake Taupo, 
Colenso. I have only three specimens. This entirely agrees with my Hobarton (Tas- 
manian) specimens described in ‘ Flora Tasmania:,’ ii. 13, as P. nudiscapum , to which the 
name nudum should be transferred. The P. nudum of the same work (p. 14), differs 
according to Archer’s specimens only in the rather longer teeth of the appendages of the 
column ; but according to his figure (t. 113 C) in the more oblong, shorter, obtuse lip, with 
ciliate edges. 
3. P. pumilum, Hook.f. FI. N. Z. i. 242. Habit and leaf of P. nudum , 
but perianth bent downwards. Lateral sepals ovale, acuminate. Petals 
similar but smaller. Lip trowel-shaped, subacute, with a broad, glandular, 
adnate plate ; claw rather long. Column short ; its lateral lobes large, 
broad, obliquely truncate and toothed. Anther apiculate. 
Northern Island, Edtjerley ; Auckland, Sinclair. Very similar to the Tasmanian 
P. despectans, H. f., if not a variety of it; but the perianth is shorter, its segments broader 
in proportion, and the lateral lobes of the column shorter. 
18. ORTHOCERAS, Br. 
Erect, glabrous, leafy, terrestrial herbs. Root of oblong tubers. Leaves 
narrow, filiform. Flowers rather large, racemed. Perianth closed. — Upper 
sepal suberect, hooded, fleshy, obtuse; lateral much longer, very narrow, 
almost filiform, quite erect. Petals minute, linear, 2-toothed at the tip. Lip 
inferior, small, 3-lobed, with small glands at its base, very shortly clawed. 
Column very short; lateral lobes subulate. Anther large, erect, persistent. 
Pollen-mosses 2, powdery, attached to the rostellum above the stigma. 
A genus of an Australian and a New Zealand species. 
1. O. Soiandri, Liudl.; — PL N. Z. i. 243. Stout, erect, 1-2 ft. high. 
Leaves filiform, with long sheathing bases, rarely linear. Raceme 1-6 in. 
long, many-flowered ; bracts large, spathaceous, exceeding the ovary. Pe- 
rianth -3- in. long, greenish-yellow. Lateral sepals \ in. long. — 0. strict um , 
A. Cunn. not Br. ; Diuris nova-Zelandice, A. Rich. Flor. 163. t. 25. f. 1. 
Northern Island: abundant on clay-bills, etc., Banks and Solander, etc. Middle 
Island: Nelson, ascending to 4000 ft., Bidwi/l. Very near indeed to the Australian 0. 
sirictum . 
OltDER, II. IRXDEiE. 
Herbs with tuberous bulbous or creeping roots or rhizomes. Leaves mostly 
radical, alternately sheathing on opposite sides of the stem, linear, late- 
rally flattened. Flowers usually large, racemed spiked or panicled, her- 
maphrodite. — Perianth superior, of 6 petaloid leaflets. Stamens 3, inserted 
at the base of the segments ; anthers opening outwards. Ovary inferior, 
3-celled ; style simple, stigmas 3, various ; ovules numerous. Capsule locu- 
licidal, 3-valved. Seeds albuminous ; embryo small. 
A very large Order, especially in Europe and South Africa, less frequmt els:where.
