Actiniopteris
(from aktin, a ray, and pteris, a fern; the fronds are radiately cut into narrow segments). ORD. Filices. Sori linear-elongated, sub-marginal; involucres (==indusia) the same shape as the sorus, folded over it, placed one on each side of the narrow segments of the frond, opening towards the midrib. A small genus of beautiful and distinct stove ferns. They thrive in a compost of equal parts crocks and charcoal, about the size of peas, which must be mixed with silver sand and a very small portion of loam and peat. About half the pot should be filled with crocks, perfect drainage being necessary. A moist atmosphere is also essential, and the plants may be syringed two or three times a day. A mean summer temperature of 78deg., with a night one of not less than 65deg., is desirable. In winter, a mean temperature of about 73deg., and a night one of not less than 60deg., should be maintained. A. radiata (rayed).* sti. densely tufted, 2in. to 6in. long. fronds fan shaped, 1in. to 1 1/2in. each way, composed of numerous dichotomous segments, half line broad, those of the fertile frond longer than those of the barren one. India, &c. (very widely distributed), 1869. In form this elegant little species is a perfect miniature of the Fan Palm, Latania borbonica. A. r. australis (southern).* fronds, segments fewer, larger, and subulate at the point. Plant much larger and more vigorous.
