Luzula.| JUNCACER. 735 
The three plants united here under the name of L. micrantha are considered 
‘by Buchenau to represent three distinct species. _I suspect that all are nothing 
more than depauperated short-stemmed forms of L. pumila. 
3. L. pumila, Hook. f. Handb. N.Z. Fl. 293.—Small, densely 
tufted, forming small cushion-shaped masses. Stems slender, 
erect, 1-2in. high. Leaves shorter than the stems, 4-1 in. long, 
linear-subulate, gradually narrowed to an obtuse tip, strict, erect, 
rigid, striate, channelled in front, convex behind, margins of the 
lower half and sheath sparingly ciliate. Inflorescence a dense 
terminal 4-10-flowered head; lowest bract foliaceous; the rest 
membranous, lacerate, pale chestnut-brown. Flowers about ;4, in. 
long, chestnut-brown. Perianth-segments subulate-lanceolate, long- 
acuminate, the 3 outer distinctly larger, dark-chestnut, without 
pale margins or with very indistinct ones. Stamens 6, about half 
as long as the perianth-segments. Capsule broadly obovoid, tri- 
gonous, from 4 to 2 the length of the perianth, dark chestnut- 
brown or almost black. Seeds oblong, minutely carunculate at the 
base.—Buchen. Monog. June. 144.

Mount Captain, Kirk! Canterbury — Mount Torlesse, Haast! T. F. C.; 
Craigieburn Mountains, Cockayne! Mount Darwin, Haast; Mount Dobson, 
T. F.C. Otago—Not uncommon on the central and western mountains, 
Petrie ! 4000-6500 ft. J anuary—Hebruary. 
Best recognised by the stems distinctly overtopping the leaves, lanceolate- 
subulate perianth-segments, which are dark-chestnut with a very inconspicuous 
pale margin, and short almost black capsule. 
4. L. Cheesemanii, Buchen. Monog. Junc. 146.—Small, densely 
tufted, forming compact patches. Stems slender, erect, 1—2in. 
high. Leaves shorter than the stems or equalling them, 3-14 in. 
long, linear-subulate, obtuse at the tip, rigid, concave in front, 
rounded on the back, grooved, margins ciliated throughout with 
long white hairs. Inflorescence of from 1 to 3 2-6-flowered 
fascicles congested into a terminal head; lowest bract leafy, often 
reddish, equalling the head; the remainder small, white, mem- 
branous. Flowers tin. long. Perianth-segments about equal, 
ovate-lanceolate, acute, thin, with a blackish-chestnut stripe down 
the centre and very broad silvery- white margins. Stamens 6, 
about half as long as the perianth-segments. Capsule shorter 
than the perianth, ovoid- globose, trigonous, mucronate, dark 
chestnut-brown or almost black. Seeds obliquely ovoid, minutely 
carunculate at the base.

Mountains, Petrie! Otago— Mount Kyeburn, Dunstan Mountains, Petrie ! 
4000-6000 ft. December-February.
