342 ORCHIDACEAE. [ Thelymitra. 
9. T. pulehella Hook. f. Fl. Nov. Zel. i (1853) 244.—Stem tall, slender, 
often flexuous, 9-18in. high or even more. Leaf shorter than the stem, 
long, linear, fleshy, grooved and channelled ; empty bracts 2-3, sheathing. 
Flowers 3-8 in a raceme from 2-6in. long, large, handsome, blue-purple, 
8 Jin. diam. Sepals and petals broadly oblong or obovate, obtuse. 
Column less than 4 as long as the perianth, the wing continued behind 
the anther but much shorter than it, 3-lobed; middle lobe short and 
broad, emarginate or truncate ; lateral lobes much longer than the middle 
lobe and almost equalling the anther, erect, lanceolate, acuminate, coarsely 
toothed. Anther broad, connective produced into a stout horn-like point.

Norru Istanp: Clay hills from the North Cape to Rotorua, not uncommon. 
Sea-level to 1200 ft. November—December. 
A handsome and well-marked species, easily distinguished by the large blue- 
purple flowers, broad obtuse petals and sepals, long erect coarsely jagged (not ciliate) 
lateral lobes of the column-wing, and broad and short middle lobe, which is much 
lower than the anther. I have seen no South Island specimens, and suspect that 
Monro’s and Lyall’s plants, mentioned by Hooker in the Handbook, are referable to 
T. pachyphylla. 
10. T. pachyphylla Cheesem. Man. N.Z. Fl. (1906) 1151.—Stem tall, 
stout or rather slender, 9-18in. high or more. Leaf shorter than the 
stem, usually very thick and fleshy, grooved and channelled, variable in 
breadth, sometimes as much as #in, across; empty bracts 2 or 3, thick 
and fleshy, sheathing. Flowers 3-6 or more, in a raceme, large and 
handsome, 3-lin. diam., blue-purple., Sepals ‘and petals oblong-ovate or 
broadly oblong, subacute. Column short, stout, about 3 as long as the 
perianth, the wing continued behind the anther but hardly as long as it, 
3-lobed; middle lobe short, broad, indistinctly hood-shaped, truncate at 
the top with an even or denticulate margin; lateral lobes longer than 
the middle one, erect or pointing forwards, flattened, the margins provided 
with numerous simple or branched fimbriae. Anther broad ; connective 
produced into a stout horn-like point which usually overtops the middle 
lobe of the column-wing. |

This has been confused with 7’. pulchella, from which, however, it totally differs 
in the structure of the column. In 1. pulchella the middle lobe of the column-wing 
is much shorter than the anther, while the lateral lobes are barely as long as it, and 
are irregularly toothed or jagged, and not at all ciliate or fimbriate. In the present 
species the middle lobe almost equals the anther, while the lateral lobes are longer 
than it, and are provided with numerous fimbriae. 
11. T. imberbis Hook. f. Fl. Nov. Zel. i (1853) 244,—Stem slender, 
wiry, often flexuous, 4-12in. high. Leaf much shorter than the stem, | 
narrow-linear, flexuous, thick and fleshy, grooved in front. Flowers 1-3, | 
rarely more, short and broad, cup-shaped, }in. diam., flesh-coloured, 
rarely white or cream-coloured. Sepals and petals 41in. long, broadly 
oblong or obovate-oblong, obtuse or apiculate. Column less than 5 as 
long as the perianth; the wing continued behind the anther but shorter 
than it, 3-lobed; middle lobe broad, truncate or obscurely 2-lobed, 
minutely warted upon the back, margin thick, entire; lateral lobes longer, 
pointing forwards and upwards, triangular, acute, irregularly denticulate,
