times divided half-way to the midrib), 2in. to 3in. long, and lin. to ljin. 

 broad : it is composed of pinna; (leaflets) of almost leathery texture, slightly 

 hairy, somewhat distantly placed, spear-shaped, and cut down nearly to the 

 rachis (stalk of the leafy portion) into narrow, toothed or slightly pinnatifid 

 divisions. This species is distinguished from all others by the sub-sessile 

 (almost stalkless) nature of its fertile portion, which is situated at the base of 

 the barren one, and formed of short, contracted segments disposed in a close 

 panicle seldom more than ljin. long. — Hooker, Synopsis Filieum, p. 434. 



A. (Anemidictyon) Sehraderiana— An-e'-mid-ic'-ty-on ; Schra-der- 



i-a'-na (Schrader's) Martins. 

 A stove species, native of South Brazil, with fronds borne on stipes 

 (stalks) 6in. to 9in. long and hairy at their base. The barren portion, 3in. 

 to 5in. long and broad, is composed of two or three pairs of pinna? (leaflets) 

 2in. to 2jin. long, lin. broad, with a wedge-shaped base, and of a terminal 

 pinna, showing two lanceolate (spear-shaped) lobes, which are of a some- 

 what leathery texture, and have a midvein extending to their extremity. 

 Their fertile portion is formed of contracted, short segments, disposed in 

 a panicle lin. to 2in, long, and borne on a stalk lin. to 4in. long. — 

 Hooker, Synopsis Filicum, p. 434. 



A. Seemanni — See-man'-ni (Seemann's). Synonymous with A. oblongifolia. 



A. tomentosa — to-men-to'-sa (woolly), Swartz. 



This handsome species, which is also known in gardens under the names 

 of A. cheilantJioides, A. deltoidea, A. flexuosa, and A. villosa, and which thrives 

 equally well under either greenhouse or stove treatment, has a wide range of 

 habitat, extending from Mexico and the West Indies to Peru and Monte 

 Video. It has a very singular appearance, produced by the rusty- coloured 

 hairs with which its strong, upright stipes (stalks), 6in. to 12in. long, are 

 densely clothed. The barren portion of the frond is 6in. to 12in. long, 

 and about half as broad, sometimes bipinnatifid (twice divided half-way to the 

 midrib), or bipinnate (divided twice quite to the midrib), and furnished 

 with pinna? (leaflets) of almost leathery texture and densely hairy on both 

 surfaces, a character which is also shared by their rachis (stalk of the leafy 

 portion). The lowest pinna? (leaflets) are the largest, and show blunt lobes
