Juncus. | LXXXVI. JUNCACEH. 47] 
[8. J.tenuis, Willd. (fig. 1065). Slender Rush.—Rootstock tufted. 
Leaves few, nearly all radical, very slender, channelled and deeply striate, 
base membranous. Flower-stems very slender, 6 to 15 inches high, 
- eylindric, wiry. Flowers in terminal panicles, sessile or pedicelled. 
Perianth-segments pale, lanceolate, acuminate. Capsule shorter, ovoid, 
obtuse or pointed. 
In wet sandy places of north-western Europe, France, Holland, and 
Germany, and the western United States; quite recently found in Here- 
fordshire, where it is very rare. EU. summer. | 
9, J. squarrosus, Linn. (fig. 1066). Heath Rush.—Leaves all radical 
or nearly so, numerous at the base of each stem, and not half its length, 
very narrow, grooved, stiff, but spreading, rarely longer and more erect. 
Flower-stem usually under a foot high, rigid, with a terminal, compound 
but not much branched panicle. Flowers usually distinct, not clustered. 
Perianth-segments about 2 lines long, rather broad, of a glossy brown, 
with broad, scarious edges. Capsule about the same length. 
On moors and heaths, in drier situations than most Junci, in central and 
northern Europe and Asia, but scarcely an Arctic plant, although in 
southern Europe chiefly confined to moorlands, Abundant in Britain. 
Fl, summer. 
10. J. bufonius, Linn. (fig. 1067). Toad Rush.—A small, pale- 
coloured annual, with numerous stems, often forming dense tufts, from 1 or 
2 to 6 or 8 inches high, branching and flowering almost from the base. 
Leaves chiefly radical, short and slender. Flowers solitary or rarely 2 or 3 
together along the branches, with the lower bracts leaf-like but short. 
Perianth-segments narrow and pointed, above 2 lines long, of a pale green, 
with scarious edges, 3 outer ones longer than the 3 others. Capsule oblong, 
shorter than the perianth. 
In wet places, widely spread over the greater part of the world, Abun- 
dant in Britain. #7. all summer, 
11. J. pygmeeus, Rich. (fig. 1068). Dwarf Rush.—A tufted annual, 
1 to 3 inches high, with the flowers collected in terminal clusters as in 
_ J. capitatus, but there are usually 3 to 5 clusters on each stem, sessile at 
the base of the branches or peduncles bearing the others. Perianth longer 
than in J. capitatus, the segments scarcely acute, striate. Capsule narrow, 
and longer than in J. capitatus. Seeds more distinctly ribbed. 
In moist, sandy situations, in western and southern Europe, from Sicily 
and Portugal, over the greater part of France, reappearing in south- 
western Scandinavia, and near the Lizard and Kynance Downs in Cornwall. 
Fl. summer, 
12, J. capitatus, Weig. (fig. 1069). Oapitate Rush.—A slender, 
tufted annual, 2 or 3 inches high, resembling the smaller specimens of 
J. bufonius, but the flowers are smaller, collected in terminal clusters of 
6 or 8, with very rarely a second or third cluster lower down. Perianth- 
segments under 2 lines long, ending in a fine, often recurved point. 
Capsule very much shorter, obovoid, Stamens usually 3. 
In sandy situations, in western and southern Europe, and again in the 
Netherlands, north Germany, and southern Scandinavia. In the British 
Isles only recorded from West Cornwall and the Channel Islands. 
Fl. summer.
