Illustrated with coloured plates and numerous wood engravings, specially prepared for this work . Ferns; Ferns. SCOL OPENDRIUM. 319 comparatively narrow, rarely rises erect, but is usually decumbent. The wings of the stalks widen out into a wedge-shaped base which is sunk between two basal auricles (ear-like appendages). These auricles are scantily developed in small fronds, but in larger ones they are more or less prominent, making the base of the frond either heart-shaped or halbert-shaped. In some specimens the auricles are drawn out into slender points as much as 4in. long. The upper part of the frond is scarcely wider than the stalk and commonly produces at the extremity a proliferous bud, which very frequently takes root and develops into a new plant (Fig. 89). The fronds are of a leathery. f/^, 89.

The short, irregular, linear-oblong spore masses are disposed on the marginal veinlets.—Hooker, Species Filicum, iv., p. 4. Nicholson, Dictionary of Gardening, iii., p. 393.

This hardy species, native of Western Siberia, Kamtschatka, Tsus-Sima, and Japan, is a singular plant, producing two totally distinct kinds of fronds. Both are of a somewhat leathery texture arid borne on stalks that are 2in. to Sin. long, naked, green upwards, and dark brown below. The barren ones, only lin. long and barely ^in. broad,, are egg-shaped and sharp-pointed, while the fertile ones. Gin. or more in length and Jin. broad, have their extremity lengthened and rooting
