13. Highland Rush, Juncus trifidus, Linn. (Fig. 1058.) 

 (Eng. Bot. t. 1482.) 



Perennial stock densely tufted, formed 

 of a shortly creeping rootstock and the 

 persistent bases of the numerous stems 

 and closely sheathing brown scales. 

 Stems slender, not 6 inches high, with 2 

 or 3 slender, filiform leaves or bracts in 

 their upper part, 2 or 3 inches long, the 

 1 or 2 uppermost having at their base 

 a single sessile flower or a cluster of 2 

 or 3. Perianth-segments very pointed, 

 rather longer than the capsule. 



In rocky and gravelly situations, in 

 northern and Arctic Europe and Asia, 

 and in the higher mountains of central 

 Europe. In Britain, only in the High- 

 lands of Scotland, where it is frequent 



on stony summits. Fl. summer.

14. Chestnut Rush. Juncus castaneus, 8m. (Fig. 1059.) 

 (Eng. Bot. t. 900.) 



The rootstock emits creeping runners. 

 Stems 6 inches to a foot high, with a few 

 rather short, grass- like, and channelled 

 radical leaves, and 1 or 2 on the stem 

 itself, all ending in a fine, nearly cylin- 

 drical tip. Flowers rather large, dark 

 brown, in 1, 2, or 3 clusters at the top 

 of the stem ; the outer bract rather 

 longer than the flowers. Perianth-seg- 

 ments pointed, nearly 2 lines long. Cap- 

 sule oblong, brown and shining, often 

 nearly twice the length of the perianth. 



In wet, rocky places, in the mountains 

 of northern Europe, Asia, and America, 

 extending all round the Arctic Circle, 

 and at great elevations in the principal 

 mountain-chains of central Europe. In 

 Britain, confined to the Scotch High- 

 ly, summer. 



lands,
