672 ORCHIDEZ. [ Thelymitra.. 
Norru Isnanp: Auckland—Swamps in the Upper Waikato, 7. F. C.; 
Omatangi, near Lake Taupo, Berggren! Taranaki—Ngaire Swamp, 7. #. C. 
Wellington—Mungaroa Swamp, Tvavers, Kirk ! 
Very near to 7. wniflora in the structure of the flower, but a taller and 
stouter plant, with numerous larger flowers, and with the lateral lobes of the 
column exceeding the anther. The late Mr. Buchanan informed me that it was. 
the plant he referred to Hpiblema in Trans. N.Z. Inst. xiv. It probably occurs 
in the South Island, but I have seen no specimens from thence. It is found in. 
several localities in New South Wales. 
8. T. uniflora, Hook. f. Fl. Antarct. i. 70.— Stem slender, 
6-12in. high or more. Leaf much shorter than the stem, very 
narrow-linear, channelled. Flowers 1-4, large, handsome, blue- 
purple, ?in. diam. Sepals and petals obovate-oblong, obtuse or 
apiculate, veined; lip broader, obovate. Column short and stout, 
less than half 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 column-lobes.—Fl. Nov. Zel. 1. 244; Handb. 
N.Z. Fl. 271. 
NortH anp SoutH Istanps, Stewart IstAnp, AUCKLAND IsLANDS: From 
Rotorua southwards, chiefly in upland districts. Sea-level to 3500 ft. De- 
cember—January. 
The name wniflora is misleading, as the flowers are often more than one. 
It is very closely allied to the Tasmanian 7. cyanea, Lindl., 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 ; disc 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. O. strictum, FR. Br. Prodr. 317.—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, chan- 
nelled, margins involute; above the leaves there are usually 2 or 3 
long sheaths with short erect lamine. Spike 1-9in. long, 3-12- 
flowered; flowers rather lax, green, greenish-purple or brownish- 
purple; bracts acuminate, the lower ones usually exceeding the
