728 JUNCACER. [Juncus. 
6. J. bufonius, Linn. Sp. Plant. 328.—Annual, pale-green, much 
branched from the base, often forming dense tufts, 3-12in. high; 
roots fibrous. Leaves radical and cauline, very narrow-linear or 
almost filiform, sheathing at the base, flat or channelled above, 
grassy, setaceous, pith not jointed. Cyme large, occupying the 
greater part of the stem; branches long or short, sometimes 
flexuous. Flowers 4+in. long, sessile or nearly so, solitary or in 
fascicles of 2-3; bracteoles broadly ovate, scarious, much shorter 
than the flowers. Perianth-segments lanceolate, acuminate, with 
broad scarious margins; the 3 inner rather shorter than the outer, 
Stamens usually 6, but sometimes 3 only in the terminal flowers. 
Capsule shorter than the erect perianth-segments, obiong, obtuse. 
Seeds numerous, minute, ovoid-oblong, obtuse, delicately lineolate.

Nortu AND SoutH IsnuANDS, CHATHAM ISLANDS, STEWART ISLAND, AUCK- 
LAND IsuANDS: From the Three Kings Islands and the North Cape southwards, 
abundant. Sea level to 4000 ft. November—January. 
Almost universally distributed in temperate climates. 
7. J. tenuis, Willd. Sp. Plant. ii. 214.—A laxly tufted peren- 
nial, with a short rhizome and numerous wiry roots. Stems several 
in a tuft, slender, erect, wiry, terete, 9-18in. high. Leaves few, 
mostly radical, usually shorter than the stem, very narrow-linear, 
grassy, flat or more generally involute or channelled; base sheath- 
ing, membranous. Cymes terminal, lax, much exceeded by the 
leafy filiform bracts. Flowers $-¢1in. long, pale-green, remote or 
clustered. Perianth-segments lanceolate, acuminate, slightly spread- 
ing in fruit. Stamens 6, about half the length of the perianth-seg- 
ments; anthers ovate. Style very short. Capsule ovoid-trigonous 
or almost globose, obtuse or slightly retuse, rather shorter than 
the perianth-segments, pale stramineous. Seeds obliquely obovoid, 
minutely apiculate.—Cheesem. in Trans. N.Z. Inst. xi. (1879) 483 ;

NortH AnD SoutH Istanps: In various localities from Mongonui to Dun- 
edin, not uncommon. Sea-level to 3000 ft. November—January. 
An abundant North American plant, extending into some parts of South 
America, found also in western Europe, &c. It is a very doubtful native of 
New Zealand, and has certainly increased its range considerably of late years. 
8. J. planifolius, &. Br. Prodr. 259.—Tufted, perfectly glabrous, 
6-18in. high. Roots many, long, fibrous. Leaves all radical, much 
shorter than the stems, numerous, flat and grassy, membranous, 
jtin. broad, dilated at the base into long imbricating sheaths. 
Flowering stems or culms long, slender, naked, bearing at the top 
an irregularly umbellately branched compound cyme; bracts at the
