and petals obovate-oblong, obtuse or apiculate, veined; lip broader, 
obovate. Column short and stout, less than 4 the length of the perianth, 
wing reduced to 2 linear-triangular lateral lobes not connected by a rim 
or crest behind the anther, tip obscurely notched, usually twisted inwards. 
Anther large, broadly ovate, the connective produced into a bifid beak 
which overtops the lateral lobes—FI. Nov. Zel. i (1853) 244; Handb.

The name uniflora is misleading, as the flowers are often more than one. The 
species is very closely allied to the Tasmanian 7. cyanea Lindl. (Hook. f. Fl. Tasm. 
(1860) t. 102), and may prove identical with it, 
7. ORTHOCERAS R. Br. 
Glabrous terrestrial herbs. Root of 1 or 2 ovoid tubers and numerous 
fleshy fibres. Leaves few, near the base of the stem, narrow-linear. 
Flowers rather large, sessile in a lax spike; bracts sheathing, acute. Upper 
sepal erect, incurved, deeply concave; lateral longer, narrow-linear or 
almost filiform, terete, erect. Petals short, erect, narrow, flat. Lip affixed 
to the base of the column, spreading, 3-lobed ; lateral lobes broad ; middle 
lobe large, ovate; dise with a thick callus. Column short, stout, upper 
part with 2 lateral erect lobes equalling the anther. Anther large, erect 
or slightly incurved, 2-celled ; pollinia powdery. 
One species only is known, found in both Australia and New Zealand. 
1. OQ. strictum #. Br. Prodr. (1810) 517.—Stem stout or slender, rigid, 
erect, wiry, 9-24in. high. Leaves several near the base of the stem, 
sheathing, 2-9in. long, linear or almost filiform, channelled, margins 
involute ; above the leaves there are usually 2 or 3 long sheaths with short 
erect laminae. Spike 1-9 in. long, 3-12-flowered; flowers rather lax, 
green, greenish-purple or brownish-purple; bracts acuminate, the lower 
ones usually exceeding the ovarv. Upper sepal 4-3 in. long, when spread 
out almost orbicular, much incurved, deeply concave; lateral filiform, 
erect or diverging, 4-lin. long. Petals thin, notched at the tip. Lip 
spreading or deflexed; lateral lobes broad, oblique; middle lobe much 
larger, ovate ; disc with a large variously shaped callus.—A. Cunn. Precur.

This species ranges in Australia from the north of New South Wales to Victoria 
and South Australia. According to Mr. Bentham, the plants from the two countries 
do not differ in the slightest particular.
