3. K. clavatum, Cheesem. Viscum clavatum, 7’. Kirk in 
Trans. N.Z. Inst. xxiv. (1892) 429, t. 37. (Manual, 622.) 
Korthalsella amentacea (Heterixia amentacea, Van Tiegh.), a New- 
Caledonian species, 1s erroneously stated in the ‘‘ Pflanzenfamilien”’ to 
be a native of New Zealand. 
LXXIX. ORCHIDEA. 
Thelymitra.—I have been unable to identify T. formosa, 
Col. in Trans. N.Z. Inst. xvi. (1884) 338; 7’. concinna, Col. l.c. 
xx. (1888) 207; TZ. nervosa, Col. l.c. 207; and 7. fimbriata, 
Col. l.c. xxii. (1890) 490. 
T. longifolia.—Ascends to 4,500 ft. on Mount Kakaramea, 
Taupo, where it is associated with the next species. 
4 bis. T. decora, Cheesem. n. sp.—Stem slender, 6-12 in. 
high or more. Leaf shorter than the stem, narrow-linear, 
thick and fleshy, channelled, 1-1in. broad; empty bracts 1-3, 
the upper one broader and more membranous. Flowers 1-4, 
about 4in. diam., dark-blue, the two lateral petals obscurely 
spotted with brown. Sepals and petals ovate-oblong, subacute. 
Column short, stout, about half the length of the perianth, 
the wing continued behind the anther and longer than it, 
3-lobed ; middle lobe the shortest but exceeding the anther, 
hood-shaped, truncate, the margin thick and fleshy and denti- 
culate, the back minutely warted, the anterior angle on each 
side slightly produced and acute; lateral lobes much larger 
than the middle lobe, pointing forwards, terminated by a dense 
rounded brush of cilia. Anther broad; connective terminating 
in a stout horn-like point. 
Norte Isnanp.—Summit of Mount Kakaramea, Taupo, and hills near 
the base of Ngauruhoe, alt. 3000-5000 ft., 7. F. C. January. 
This is probably nearer to Berggren’s 7’. intermedia than to any other 
species, but (judging from his plate and description) differs in the broader 
and more truncate middle lobe of the column-wing, which is denticulate 
on the margin and warted on the back, and not at all bifid, and in the 
much shorter and more densely ciliate lateral lobes. TJ. longifolia is at 
once removed by the much longer and more distinctly hooded middle lobe 
of the column-wing, with an entire margin and smooth back, and by the 
shorter and more densely ciliate lateral lobes, which do not exceed the 
middle lobe. 
4 ter. T. pachyphylla, Cheesem. n. sp.—Stem tall, stout 
or rather slender, 9-18 in. 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
