HEXANDRIA— MONOGYNIA. Luciola. 183 



On the grassy summit of Ben Lomond. — Found by Mr. Joseph 

 Woods, on Fairfield, near Ambleside, Westmoreland. Mr. Bi- 

 cheno. 



Perennial. July, August. 



Root of many tufted fibres. Stem solitary, a span high, erect, 

 round, striated, slender, bearing 2 or 3 leaves. Radical leaves 

 several, tufted, shortish, spreading, linear-lanceolate, nearly or 

 quite flat, bearing a few long scattered hairs ; stem-leaves chan- 

 nelled, upright, narrow, with long sheaths. Panicle with 1 or 

 2 erect, leafy bracteas, solitary, terminal, drooping, an inch or 

 more in length, dark chocolate-coloured, ovate-oblong, obtuse, 

 many-flowered, dense, compound, more or less lobed, especi- 

 ally at the base, intermixed with lanceolate, pointed, membra- 

 nous, fringed or jagged, brown, interior bracteas, various in 

 length. Fl. nearly sessile, crowded, erect. Calyx-leaves lan- 

 ceolate, dark brown, with a slender point, rather longer than the 

 capsule, which is elliptical rather than ovate, slightly pointed 

 with the base of the style, of a varnished chocolate brown ; the 

 valves thickened at the edges, and each furnished with a central 

 rib, or rudiment of a partition, but not more than in other spe- 

 cies. Seeds elliptical, nearly sessile, with some occasional traces 

 of a lateral line, but no decided crest. 



Juncus pediformis of \'illars, unknown in Britain, is indeed nearly 

 akin to this plant, but much larger, paler, more lax in the pa- 

 nicle, and with broader leaves. The capsule is ovate, tapering 

 into a sharp point. Wahlenberg associates it with the following, 

 as a variety, but they appear very difi'erent. 



7. L. arcuata. Curved Mountain Wood-rush. 



Panicle somewhat umbellate, partly compound, with droop- 

 ing branches. Heads globose, of few flowers. Bracteas 

 membranous, fringed. Capsule elliptical. Leaves chan- 

 nelled.

On the mountains of Scotland. 



On the most stony and barren summits of Cairngorum, and others

Perennial. July. 



Root rather woody ; tufted and branched at the summit, invested 

 with several ribbed scaly sheaths. Stem 3 or 4 inches high, 

 erect, round, striated, bearing 1 or 2 leaves. Radical leaves 

 numerous, tufted, incurved, linear, channelled, very slightly 

 and partially hairy ; stem-leaves somewhat flatter, with long 

 reddish sheaths. FL about 3 together, in small, round, more or 

 less stalked, heads, collected into a terminal panicle, whose 

 somewhat umbellate, recurved branches, various in number and 

 length, occasionally divided, are sheathed at their origin with one
