CVI. JUNCACEJE 
least twice the length of the perianth ; this form occurs on rocks near the top 
of Huttoo, flowering September-October. The Simla specimens appear more 
nearly allied to J. membranaceus, Eoyle, FI. Br. Ind. vi. 397, except that the 
clusters are rarely solitary. 
2. LTJZTJLA. From the Latin luciola, a glow-worm, referring 
to the shining flower-clusters. — Temperate and cold regions. 
*Luzula campestris, DC.; FI. Br. Ind. vi. 401. A small, hairy 
herb ; rootstock creeping ; stems 6-12 in., slender, tufted. 
Leaves 2-3 in., chiefly near the base of the stem, grass-like, fringed 
with long, white hairs. Flowers dark brown, sessile in several 
stalked, ovoid clusters J in. long in the forks and at the ends of 
the very unequal branches of a short, erect, terminal panicle. 
Perianth-segments 6, scarious. Stamens 6, shorter than the peri- 
anth. Ovary 1-celled ; style-branches very long ; ovules 3. Capsule 
slightly shorter than the perianth, ovoid-oblong, pointed ; seeds 3. 
Himalaya, in grass, 10,000-14,000 ft.; July, August. — Hilly districts 
throughout India. — Temperate and cold regions (Britain, Wood Bush). 
CVII. ARACEyE 
Perennial herbs ; rootstock tuberous or thick and creeping. 
Leaves various, radical or alternate, margins entire or nearly so. 
Inflorescence of numerous, small, 1-sexual flowers, sessile and 
usually crowded on a fleshy, erect column or spadix terminat- 
ing the stem and more or less enclosed in a large bract or spathe. 
The lower portion of the spathe, called the spathe-tube, is folded 
round the spadix, while the upper portion or spathe-limb is open 
and spreading, rarely having its margins inrolled. Male and 
female flowers on the same or on different plants ; if a spadix 
bears flowers of both sexes they are in distinct zones, the female 
always below the male and usually the two are separated by a 
zone of neutral organs. In some genera the spadix is prolonged 
above the flowers in a barren, tail-like, rarely club-shaped appen- 
dage. Male flowers : perianth none ; anthers 2-5, sessile. Female 
flowers : perianth none ; ovary globose or ovoid, 1-celled, ovules 1 
or 2, sometimes several, stigma sessile. Two-sexual flowers : peri- 
anth 6-parted ; stamens 6 ; ovary 3-celled, ovules many, stigma 
sessile. Fruit a spike or head of berries, sometimes enveloped in 
the persistent spathe-tube. — Temperate and tropical regions, chiefly 
the latter. 
Acorns is exceptional in having bisexual flowers and in the spadix not being 
enclosed by the spathe.
