attenuated point membranous and jagged. — E. B. 1727. N. 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.

 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-

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

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

Order CII. CHARACE^. 



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
