Eaton states that this pretty, greenhouse species, of small dimensions, grows in rocky places, in the Sierra of California, at 4000ft. elevation, and that it was first collected in 1869. Its spear-shaped fronds, 4in. to Gin. long and borne on stalks of the same length, are produced from a short- creeping, knotted rootstock, which is chafly with very narrow, rusty-brown scales toothed at their edges. They are bipinnate (twice divided to the midrib), and furnished with very short, stalkless pinnules (leafits) often broader than long, seven to nine to a leaflet, closely placed (Fig. 18), of a leathery texture, dull green in colour, pointed at the tip, and rounded at the base ; their edge is so conspicuously revolute (rolled in) as to make the leafits appear almost cylindrical. The sori (spore masses), disposed near the end of the veinlets, are covered by the revolute margins of the leafits. — Hooker, Synopsis Filicum, p. 477.
