derable length, but tlie ascending brandies are much more divided, forming 

 close clusters or tufts, 2 to 3 inches high. Leaves scarcely above a line long, 

 few on the creeping stems, numerous on the branches, and closely imbricated 

 in 4 rows. Spikes about | inch long, closely sessile, and sohtary at the ex- 

 tremity of the leafy branches. 



In mountain pastm-es, in Europe and central and Russian Asia, extending 

 from the Pyrenees and Alps to the Arctic regions. In Britain, common in 

 the mountains of Scotland, northern Ireland, and northern and central 

 England, and in one locality in Somersetshire. Fr. summer. 



4. Fir Clubmoss. Iiycopodium Selago, Linn. 

 (Eng. Bot. t. 233.) 



Stems scarcely creeping, though sUghtly decumbent and rooting at the 

 base ; the forked branches forming dense, level-topped tufts, 3 or 4 inches 

 high, completely covered with their crowded but spreading dark-green 

 leaves, all lanceolate, 3 or 4 lines long, with a short fine point. Capsules in 

 the axils of the upper leaves, not forming a distinct spike ; they are some- 

 times replaced by little pedicellate leafy bulbs. 



In hilly pastures, in Europe, Russian Asia, and North America, extend- 

 ing from Spain, northern Italy, and the Caucasus to the Arctic regions, 

 and in the southern hemisphere. Frequent in all hilly parts of Britain, 

 except some of the southern counties of England. Fr. summer and autumn. 



5. Marsh Clubmoss. Iiycopodium inundatum, Linn. 

 (Eng. Bot. t 239.) 



Stems slender and creeping, scarcely branched, seldom above 2 inches 

 long, with narrow-linear leaves, about 2 lines long, all turned upwards. 

 Fruiting branches soUtary, simple and erect, 1| to 3 inches high, with 

 leaves like those of the stem, but loosely scattered all round. The upper 

 end of the branch is thickened into a fruiting spike, from f to 1 inch long : 

 the bracts very hke the stem-leaves but broader at the base. 



In heathy bogs and sandy swamps, dispersed over the greater part of 

 Europe, especially the western States, and in North America, but not re- 

 corded either from Asia or the Arctic regions. Ii-regularly distributed over 

 various parts of Scotland and England, but not common, and not known in 

 Ireland. Fr. summer and autumn. 



6. Ziesser Clubmoss. Iiycopodium .selaginoides, Linn. 

 (Eng. Bot. t. 1148.) 



Stems slender, prostrate, much branched, forming moss-liie patches 3 or 

 4 inches in diameter. Leaves spreading, lanceolate, pointed, 1 to 1^ lines 

 long, not so densely crowded as in the other species. Fruiting branches 

 ascending or erect, solitary and simple, with rather longer leaves ; those of 

 the spike or fruiting part full 2 Unes long, lanceolate, and bordered with a 

 few fine teeth. Spike ^ to J inch long, the upper capsules fiUed witli 

 a minute powdery dust, the lower containing larger grains. 



In moist moimtain pastures, and wet, stony places, in Em-ope, Russian 

 Asia, and North America, extending from the Alps and Pyrenees to the 

 Arctic regions. Not uncommon in Scotland, northern and central England, 

 North Wales, and northern Ireland. Fr. summer and autv/mn.
