59 
inches long, and but slightly branched, bearing fibrous roots all 
along ist lower surface. Branches simple, barren ones decumbent, 
fertile ones upright. Leaves irregularly placed, crowded, linear 
lanceolate, acute, all turned upwards. Spikes solitary, terminal, 
green, one inch long, quite erect. Scales linear, dilated at the base, 
curved upwards, entire or with one or two teeth only in luxuriant 
specimens. 
This plant, which, like the rest of its tribe, is perennial, shows very strikingly 
the manner of growth of nil the creeping species, though there are few of them 
so rapid in their decay as this. It creeps along the ground, and grows at one 
end as it decays at the other ; thus if its habitat bo a level piece of mud, as it 
generally is on commons, &c., tho effect is easily seen in a black mark or line 
of tho decayed plant, sometimes for many inches boyond where it is then 
vegetating. It ceases to grow in the winter, but continues to decay ; thus very 
many plants are exterminated, and only tho vigorous ones have strength to put 
forth new foliage, of these a very small portion generally remains, and thus it 
is that the plants are always small in the early part of the season.

Des. — Stems creeping, slightly branched, 2 or 3 inches long. 
Barren branches delicate, recumbent, simple. Fertile branches up- 
right, rigid, bearing a solitary spike. Leaves lanceolate, acute, 
toothed, imbricated, bright green. Spike large, oblong, cylindrical, 
yellowish, and terminal. Scales much larger and wider than the 
leaves, and deeply toothed, spreading widely on account of the very 
large capsules. 
This plant show's very well the two sorts of capsules ; those in the low r er part
