Stems recumbent at the base ; brandies erect, annually pro-

In Carnarvonshire, especially on mount Glyder. Mr. Lh'xyd. On 

 the sides of the Highland mountains, but not common. Light-

 the Highlands of Scotland. Mr. G. Don. 



Perennial. June — August. 



A large and handsome species, often a foot high, though the lower 

 part of the stem is recumbent and creeping, throwing out seve- 

 ral branched radicles. The flowering branches are erect, densely 

 leafy, but little subdivided, each terminating in a solitary up- 

 right spike, whose scales being deciduous, seem to leave the 

 branch partly naked ; but it afterwards bears proper leaves, ex- 

 cept a few diminished ones, just under where the spike had been, 

 and produces, in the following season, another spike. Hence 

 the jointed, or interrupted, aspect of the branches. The leaves 

 are crowded, spreading in five rows, lanceolate, nearly flat, 

 somewhat serrated, with a sharp naked point, but not awned, 

 nor bearded. Spikes rather tawny, an inch, or when at matu- 

 rity an inch and half, long ; their scales shortened, and much 

 dilated in width, assuming an ovate, or sometimes a kidney-like, 

 shape, though always pointed. Caps, kidney-shaped, but smaller. 



We have this species from North America, and Mr. Menzies 

 brought it also from Banks's isles, on the north-west coast of 

 that continent. 



6. L. alpinum. Savin-leaved Club- moss. 



Stems prostrate. Branches erect, clustered, forked, level- 

 topped. Leaves acute, keeled, imbricated in four rows. 

 Scales of the spikes ovate-lanceolate, flat.
