Hab. First detected in this country, by the Rev. R. B. Francis, growing on decaying stumps 
of trees in Edgefield Wood ; also at the foot of alders in Hanworth Meadows, Norfolk, 
and in an alder car, at East Sheal, Lincolnshire. I have since found it not rare in similar 
situations in various parts of Suffolk, as well as very abundantly upon rocks at 1 unbridge 
Wells. — Mr. Lyell has also discovered it in the New Forest, Hampshire, where he has 
observed the male fructification to be produced in November. The female is found in 
the early spring months. 
Plant growing in rather small and loosely-entangled patches, frequently among moss. 
The Roots in the present, as well as in the species last described, originate here and there 
from nearly, the whole length of the under side of the plant, but mostly in small tufts 
immediately below the stipules (f. 5). 
Surculi from half to three quarters of an inch in length, procumbent, flexuosc, with 
their apices, as well as those of the simple shoots and ramuli, erect, of a pale green 
color. 
Leaves (f. f. 2. 3. 4. 5.6) scarcely ever exceeding half a line in length, frequently less, 
especially at the base, and towards the extremity of the plant j more or less closely
