Scolopendrium—H a rt’s-tongue. Vulgare—Common.
Jugosum—F u ll o f ridges.
T h i s singular F e rn was found in Guernsey by Mr. James,
of Vauvert, and Mr. Jackson.
I t differs in having the soriferous veins thickened, and thus
producing on the upper surface of the fronds a series of ridges,
or leafy sorus-like excrescences.
The length is from twelve to fourteen inches.
There are several forms in cultivation.
For the specimen illustrated I am indebted to Mr. C.
Monkman, of Malton.
