2. L. anmt'inum (L.) ; 1. loosely scattered lanceolate mucro- 
nate serrulate, sjnkes sessile solitary terminal, scales roundish 
shortly acuminate membranous and jagged. — E. B. 1727. K. 
361. — St. very long. Branches rather long, erect, each year's

entire, spikes sessile solitary terminal, scales ovate-lanceolate 
flat, branches erect clustered forked level-topped. — E. B. 234. 
If. F. 53. A'. 365. — St. long prostrate ; also a subterranean 
rhizome. Fertile branches usually twice dichotomous, each 
division ending in a short cylindrical yellowish-green spike 
rather thicker than the branch. [Large forms with flattened br. have 
been mistakeu for L. eomplanatum (L.), which may be distinguished by its 
conspicuously stallcnd spikes, which are usually not solitary, and its more 
linear 1.] — Stony moors. p. VIII. Savin-leaved Club-moss.

minal sessile leafy solitary upon short erect branches. — E. B.

Branches few, simple, fertile. Bracts subulate from a dilated

** St. decumbent heloiv, then erect. Caj^s. in axils of upper leaves 
solitary. No spikes. L. all alike. Plananthus Beauv. 
5. L. Seldyo (L.) ; I. in eight roivs crowded uniform linear- 
lanceolate acuminate, caps, not spiked but in the axils of the 
common leaves, st. erect forked level-topped. — E. B. 233. //. /•'. 
54. N. 375. — St. short, erect or slightly decumbent, densely 
leafy. No separate spikes. At the extremity of the stem a 
few curious viviparous buds may usually be found ; they are 
well illustrated by Mr Newman (p. 378). Occasionally the 
stems in sheltered situations become much lengthened. — 
Heaths, chiefly on mountains. P. VI. — VIII. Fir Club-moss.
