FERNS. 
[ Lycopodium . 
Syn. — Lycopodium inundatum of botanists. — Plananthus inundatus, Beam. 
Fig. — E. B. 239.— Flo. Dan. 336.— J Dillen Mus. 62, /. 7 {good). 
Des. — Stem very closely appressecl to the ground, 1 to 2 inches 
long, and hut slightly branched, bearing fibrous roots all along its 
lower surface. Branches simple, barren ones decumbent, fertile 
ones upright. Leaves irregularly placed, crowded, linear lanceolate, 
acute, all turned upwards. Spikes solitary, terminal, green, 1 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 all 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 be a level piece of mud, as 
it generally is on commons, &c., the effect is easily seen in a black mark or line 
of the decayed plant, sometimes for many inches beyond where it is then vege- 
tating. It ceases to grow in the winter, but continues to decay ; thus very many 
plants are exterminated, and only the 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. 
Sit. — O n wet moors and commons, particularly where turf has been pared.
