Angiopteris
(from aggeion, a vessel, and pteris, a wing). Including Psilodochea. ORD. Filices. A genus of gigantic greenhouse ferns. Capsules eight to fifteen, opening by a slit down the side, sessile, very close but not concrete, arranged in linear-oblong or boat-shaped sori near the edge of the frond. These ferns require a very liberal supply of water, and plenty of room to fully expand. The most suitable compost is a mixture of strong loam and peat, with some sharp sand. Thorough drainage must be afforded. A. evecta (evectic). cau. erect, 2ft. to 6ft. high 1 1/2ft. to 2ft. thick, very fleshy. sti. swollen and articulated at the base, furnished with two large leathery persistent auricles. fronds 6ft. to 15ft. long, bi-or tripinnate; pinnae. 1ft, to 3ft. long, spreading, the lowest the largest; rachis swollen at the base; pinnules 4in. to 12in. long, 1/2in. to 1 1/2in. broad, linear-oblong, sessile or shortly stalked, acuminate; edge entire or finely toothed. Tropics of Old World. This is the only clearly defined species; the others usually known as distinct species are but varieties of it, and its culture should not be attempted if plenty of room cannot be afforded it.
