FERNY COMBES.

Tunbriclgense it is partially embedded in the mem¬ 
branous portion of the frond, and the mouth is 
slightly jagged, whilst the frond is stiff and up¬ 
right. In unilaterale the receptacle has a short 
winged footstalk; the mouth formed like the bill 
of a duck, not jagged. The frond is curved, and 
the pinnae all turned on one side. H. unilaterale 
is common on the Plym and at Lynmouth.

(Plate II. Pig. 1.) 
Fronds irregularly thrice divided; pinnules fan¬ 
shaped, with hair-like stems ; the sori placed in 
lines along the edge of the pinnule, a portion of 
which turns back and forms an indusium; root 
creeping, about the thickness of a quill, scaly, with 
hairy fibres. The root greatly resembles that of 
the smaller and more delicate species of Poly podium. 
One of our most local ferns, growing in rents in 
the cliffs where water trickles down. In the neigh¬ 
bourhood of Ilfracombe, where it is or rather was 
abundant, it invariably chooses those places where 
the water flows through or over lime rock. There 
are many places on the coast where the mosses that 
delight in moisture are gradually being transformed 
into stone by the dripping of these springs in 
which the Maiden-hair rejoices.
