Var. macrostemon Buchen. in Oesterr. Bot. Zeit. (1898) 210.—Stamens distinctly 
overtopping the perianth-segments ; seeds not carunculate. ~* 
Easily distinguished by its small size and very short stems, the flowers being sunk 
among the leaves. Buchenau’s var. macrostemon, separated on account of the stamens 
slightly exceeding the perianth, does not appear to me to be really distinct, the stamens 
often varying in length. 
2. L. micrantha Buchen. in Oesterr. Bot. Zeit. (1898) 166, 243.—Densely 
tufted, forming compact rounded patches. Stems rigid, erect, 4-11 in. 
high, leafy at the base. Leaves equalling the stems, straight, rigid, erect, 
narrow-linear, obtuse at the tip, broadly sheathing at the base, flat or 
slightly concave in front, rounded or almost flat at the back; margins 
cartilaginous, glabrous; sheaths membranous, striate, slightly ciliate at the 
tip. Inflorescence simple, terminal, capitate, 3-8-flowered:; the lowest 
bract (or the 2 lowest) foliaceous, overtopping the inflorescence, the remainder 
small, membranous, lacerate. Flowers about yoin. long. Perianth- 
segments equal, lanceolate, acute, reddish-brown, with very narrow hyaline 
margins. Stamens 6, rather more than } as long as the perianth-segments, 
Capsule elliptic-trigonous, almost equalling the perianth, acute, shining, 
red-brown, paler at the base——Pflanzenr. Heft 25 (1906) 96; Cheesem.

Var. triamdra/Oheesem. Wan. NZ. Fl. (1906) 734, —Sive and habit of the type, 
but leaves rather narrower, often curved, and usually canaliculate. Heads 6-12- 
flowered. Stamens 3.-—-L. triandra RBuchen. l.c. 
Var. erenulatayChocsem. i.c.—Very densely pulvinate. Leaves very narrow, subu- 
late, canaliculate. Inflorescence 2~6-flowered. Perianth-segments crenulate at the 
tips. Stamens 6. Capsule obovoid, trigonous, obtuse.—L. crenulata Buchen. Lc.

Rock and Pillar Range, Petrie / 4000-6000 ft. December--February. 
The three plants united here under the name of L. micrantha are considered by 
Buchenau to represent three distinct species. I possess very poor material; but so 
far as it goes, I should hesitate at giving them higher rank than that of varieties. 
3. L. pumila Hook. f. Handb. N.Z. Fl. (1864) 293.— Small, densely 
tufted, forming small cushion-shaped masses. Stems slender, erect, 1-2 in. 
high. Leaves shorter than the stems, 4-1 in. long, linear-subulate, gradu-- 
ally 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 + in. 
long, chestnut-brown. Perianth-segments subulate-lanceolate, long acumi- 
nate, the 3 outer distinctly larger, dark-chestnut, without pale margins or 
with very indistinct ones. Stamens 6, about $ as long as the perianth- 
segments. Capsule broadly obovoid, trigonous, from } to 2 the length’ 
of the perianth, dark chestnut-brown or almost black. Seeds oblong, 
minutely carunculate at the base.—Buchen. Monog. Junc. (1890) 144; 
Pflanzenr. Heft 25 (1906) 97; Cheesem. Man. N.Z. Fl. (1906) 735.
