The leafits, of a soft, papery texture and yellowish-green colour, are egg-shaped when barren, except the terminal ones, which usually are distinctly halbert-shaped and un- dulated on their margins: these characters are much more con- spicuous when the plant is fertile (Fig. 22 shows barren fronds only). The fronds are smooth on both surfaces, and the sori (spore masses), disposed in a continuous, marginal line, are provided with a somewhat narrow, thin involucre, nearly or quite hidden when the spores are ripe.—Hooker, Species Filicum, ii., p. 145; Filices Exoticce, t, 50.

A delicate-looking, greenhouse species, native of Mexico and Guatemala, with broadly spear-shaped fronds, 6in. to 12in. long, 2in. to 4in. broad, twice divided nearly to the midrib, and borne on tufted, upright, dark chestnut-brown, polished stalks Sin. to Gin. long. The spear-shaped leaflets (Fig. 23), 2in. to Sin. long, lin. broad, and opposite, are cut down nearly to the rachis into long, narrow-oblong leafits, of a somewhat leathery texture, pale or glaucous green in colour, and smooth on both surfaces. The abundant and conspicuous sori (spore masses) are disposed in a continuous, single, intramarginal row, and covered by a br
