sessile by a broad base, acuminate, blunt or truncate and retuse, with an exserted costa, opaque, coriaceous, 4-1 
inch long. Fertile pinne didymous, stipitate. Capsule large, oblong, two-lobed, the lobes divaricating, splitting 
into two valves through both lobes, placed at the forking of a pinnule. Spores very minute, oblong, curved.—Two 
species have been made of this plant, one for the truncate-leaved, and the other for the acuminate-leaved, but both 
forms may be found on one specimen. (Name from runos, a notch, and wrepıs, a Fern ; from the split pinnules.)

A large genus, whose species are generally very widely diffused, several being found in most climates and 
latitudes. The genus has been monographed by M. Spring in the fifteenth and twenty-fourth volumes of the 
* Memoirs of the Brussels Academy. —Fronds erect from a creeping rhizome, climbing or pendulous, leafy. Leaves 
small, distichous, trifarious, quadrifarious, or imbricated. Capsules in sessile or peduncled, terete, angled, or square 
spikes, or sessile in the axils of the leaves, kidney-shaped, sessile, one-celled, bursting longitudinally all round, and 
full of minute trigonous spores, each marked with three diverging lines. (Name from Avxos, a wolf, and rovs, a 
foot; from some fancied resemblance.) 
$ a. SELAGO.— Leaves imbricated all round the stem. Capsules axillary in the upper leaves or in the bracts of 
terminal, sessile, quadrifarious spikes.

This is a very widely diffused plant, always growing in mooriands or open boggy grounds, often on mountains. 
—Stems stout, rigid, tufted, branched or simple, often decumbent at the base, erect, cylindrical, 4-8 inches high, 
blunt, J— inch diameter. Leaves closely imbricated up and round the whole stem, rarely spreading, broadly subu- 
late or lanceolate-subulate, acute or acuminate, 2 lines long. Capsules sessile amongst the upper leaves. —PLATE
