Anemia
(from aneimon, naked; in reference to the naked panicles of sporangia). Including Anemidictyon. ORD. Filices. A well-marked genus of stove and greenhouse ferns, chiefly confined to Tropical America. Capsules small, very abundant, forming a copiously-branched panicle, quite distinct from the leafy part of the frond. This genus of handsome dwarf-growing ferns is of easy culture, in a compost of fibrous peat, leaf soil, and sand. Several species are exceedingly pretty for fern cases. For general culture, see Ferns.

Dregeana (Drege's).* sti. 8in. to 12in. long, firm, slightly villose. fronds, barren portion sub-sessile, 8in. to 12in. long, 2in. to 3in. broad, about equal in width in the lower half, with eight to twelve pinnae on each side, which are 1in. to 1 1/2in. long, 1/2in. to 3/4in. broad, ovate-deltoid, unequal at the base, the upper side sub-cordate, the edge inciso-crenate; panicle 3in. to 4in. long, the lower branches elongated; peduncle same length. Natal. Stove species.

A. hirsuta (hairy). sti. 6in. to 12in. long, slender, naked. fronds, barren portion 2in. to 6in. long, 1in. to 3in. broad, sessile, oblong-deltoid, bipinnatifid; pinnae in six to eight opposite pairs, 1in. to 1 1/2in. long, 1/4in. to 3/4in. broad, varying from oblong, obtuse, subentire, truncate at the base on the lower side, to deeply pinnatifid with narrow divisions; panicle 1in. to 2in. long, close; peduncle 2in. to 6in. long, slender. Jamaica, 1704. Very handsome stove species. SYNS. A repens and A. ciliata. A. hirta (hairy). Synonymous with A. collina.
A. mandioccana (Mandioccan).* sti. 6in. to 12in. long, deciduously villose. fronds, barren portion 1ft. or more long, 2in. to 4in. broad, oblong-lanceolate, the lower half about equal in width; pinnae in twenty or more close pairs, the point narrowed, but scarcely acute; edge finely serrulate, the upper base parallel with the stem, the lower obliquely truncate; rachis and surfaces finely pilose; texture sub-coriaceous; panicle very compound, 3in. to 4in. long; peduncle longer. Brazil. A very beautiful and distinct stove species.
A. Phyllitidis (Phyllitis-like).* sti. 6in. to 18in. long, stramineous, naked, or fibrillose. fronds, barren portion sessile, 4in. to 12in. long, 2in. to 8in. broad, ovate-oblong, simply pinnate; pinnae in four to twelve sessile pairs, the lowest the largest, ovate, 1in. to 6in. long, 1/2in. to 2in. broad, the apex acute, the edge crenulate, the base rounded or cuneate, or unequal, with a firm texture; panicle dense, 3in. to 9in. long, the branches short; peduncles the same length. Cuba, Mexico, &c. SYN. Anemidictyon Phyllitidis. Greenhouse species.
A. P. lineata (lined). fronds with a yellowish-green central stripe down the pinnae. South America, 1868.
A. P. plumbea (leaden). Synonymous with A. P. tessellata. A. P. tessellata (tessellated). Pinnae dark green, with bright green centre and leaden-grey border. Brazil, 1875. The forms of this species are numerous: fraxinifolia and macrophylla are names often met with, but only show slight deviations. They allhave a more hardy constitution than the other species, and grow well in the greenhouse. SYN. A. P. plumbea.
