Hab. By no means uncommon in the alpine and mountainous parts of England, Scotland, 
and Ireland : generally preferring moist heaths, or sandy ground, which is occasionally 
inundated. — (It bears capsules in the spring months : Gemma are found throughout the 
whole year.) 
Plant growing in patches of various dimensions ; the individuals separate, or, as is frequently the 
case, imbricating one another, like the fronds of J. pinguis and J. epiphylla. 
Roots more or less numerous, and crowded on different plants, and even on different parts of 
the same plant, yet frequently extending the whole length of the underside of the nerve, 
from which alone they originate : they are simple, fibrous, pellucid, whitish. 
Frond lying horizontally upon the ground, yet with the apices often erect, from a quarter of 
an inch to an inch in length, varying remarkably in figure, for the most part oblong, some-
