[. Lycopodium . 
Sit. — On the grassy sides of mountains. 
Hab, — At 1000 yards of elevation on Carnedd David, Caernarvonshire, 
probably 1200 yards in Aberdeenshire ; also to the summit of Ben Hope, in 
Sutherland, at 1000 yards or thereabouts, where the climate is probably less 
genial than that at 1200 yards in Aberdeenshire ; to 1150 yards on Ben Nevis, 
and descending to the base of the mountains. Too plentiful on all the mountain 
tracts of Scotland to call for particular localities. On most of the Cumberland 
and Yorkshire mountains, Mr. H. C. Watson. Somerset, Mr. A. Southby. 
Near Todmorden, Lancashire, at a very low elevation (a single root only), Mr.

(Plate 8, fig. G.) 
Cha. — Stem erect, dichotomously branched, flat at top. Leaves

Fig. — E. B. 233.— Flo. Dan. 104.— Dill. Mus. t. 5G, /. 1. 
Des. — Root tufted, fibrous. Stems 2 to 6 inches high, growing 
quite erect, one issuing only from the root, and this becoming divided 
dichotomously until they form a cluster of from six to ten ultimate 
divisions ; the upper fruitful branches are, however, scarcely more 
than forked. Leaves in eight rows, of a dark shining green color, 
crowded, lanceolate, entire, acute, convex on the outer side, a little 
spreading, and curved upwards. The fruit is not borne in a terminal 
spike, as in the other species, but in the axils of the common leaves, 
all down the upper part of the stem. Capsules large, kidney-shaped, 
regularly two-valved, opening by a transverse fissure, and scattering 
minute, yellow,, globular, smooth spores. 
This plant is likewise viviparous, producing not only capsules of seeds, but 
occasionally also curious petioled buds, which consist of three or four differently- 
sized ovate leaves ; they are irregularly 'placed in the axils of the common leaves, 
that is, in the place of the capsules. 
Sit. — On mountain sides, &c. 
H ab. — It attains the summit of Ben-na-Muich-dhu, the loftiest of the 
northern Grampians or Caimgorum range, and the second summit of Britain 
(4320 feet). Common everywhere on the hilly tracts of Britain, especially the 
Scottish Highlands. — Eng. : Helvellyn, Skiddaw, ike. ; on the loftiest rocks of
