attenuated point membranous and jagged. E. B. 1/27. -^ 361. 

 St. prostrate, long. Branches rather long, erect, each year's 

 growth marked by a spot where the leaves are adpressed. Spikes 

 cylindrical, greenish-yellow, not persistent. Stony mountains. 

 Rare in Caernarvonshire and Cumberland. Common in the 

 Highlands of Scotland. P. VIII. E. S. 



3. L. alpinum (L.); I. in four rows imbricated acute keeled 

 entire, spikes sessile solitary terminal, scales ovate -lanceolate 

 flat, branches erect clustered forked level-topped. E. B. 234. 

 N. 365. St. prostrate, long. Fertile branches usually twice di- 

 chotomous, each division ending in a short cylindrical yellowish- 

 green spike rather thicker than the branch. Elevated mountains. 

 P. VIII. Savin-leaved Club-moss. 



4. L. Selago (L.) ; I. in eight rows crowded uniform linear- 

 lanceolate acuminate, caps, not spiked but in the axils of the 

 common leaves, st. erect forked level-topped. E.B.233. N. 375. 

 St. short, erect or slightly decumbent, densely leafy. No 

 separate spikes. At the extremity of the stems 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 elongated. Heaths, chiefly on moun- 

 tains. P. VI. VIII. Fir Club-moss.

 spikes terminal sessile leafy solitary upon short erect branches.

 1148. A r . 371. S. spinulosa K och. St. prostrate, much branched, 

 rooting, slender. Flowering branches simple, short, erect. In 

 addition to the 2-valved capsules, this plant produces others which 

 contain 2 4 large grains. Boggy spots chiefly in mountainous 

 places. P. VIII. 



Order CII. CHARACE.E. 



Leafless branched plants with stems formed of one or more 

 parallel tubes. Two kinds of fructification : round red globules 

 (anthers ?) formed of 8 valves, inclosing cells containing granular 

 matter and spiral filaments ; oval nucules formed of 1 cell with 

 5 filaments folded spirally round it and containing minute gra- 

 nules which appear at last to unite into a single seed. Plants 

 green, aquatic. The position of this Order is very doubtful, and
