A. (Euasplenium) lineatum— Eu-as-ple'-ni-um ; li-ne-a'-tum (streaked), 

 Swartz. 



This singular, stove species, native of the Mauritius and Bourbon 

 Islands, is a very puzzling plant on account of its gradually running into 

 forms with leaflets again pinnate, which have either small, narrow-linear 

 pinnules (leafits) such as in Darea incequalis of Willdenow and D. bifida of 

 Kaulfuss, or even these latter again deeply bifid (twice-cleft) or pinnatifid 

 (cut half-way to the midrib) as in D. bifida and D. violescens of Bory. Its 

 fronds, 1ft. to 2ft. in length, 4m. to 6in. in breadth, and borne on firm, 

 erect stalks 6in. to 9m. long and more or less scaly, are, however, usually 

 simply pinnate (once divided to the midrib) ; the twenty or thirty sessile 

 pinnae (stalkless leaflets) on each side of their midrib are of a thin texture, 

 of a dark' green colour, and toothed throughout. The sori (spore masses) 

 are disposed in very regular rows reaching from the midrib nearly to the 

 edge. — Hooker, Species Filicum, hi, p. 104. Nicholson, Dictionary of 

 Gardening, i., p. 131. 



A. (Anisogonium) lineolatum — An-is-og-o'-ni-um ; li-ne-ol-a'-tum 

 (slightly streaked), Mettenius. 

 A stove species, native of the Philippines and the Malayan Peninsula and 

 Islands. The fronds are occasionally simple (undivided), but are usually 

 composed of a terminal leaflet and from three to six pairs of lateral ones 

 Gin. to 12in. long and 2in. or more broad, equally entire, and of a leathery 

 texture. The sori (spore masses) are disposed in slender lines extending from 

 the midrib to the edge.— Hooker, Species Filicum, hi., p. 268. Beddome, 

 Ferns of British India, t. 330. 



A. (Euasplenium) longicauda — Eu-as-ple'-m-uni ; long-ic-au'-da (having 

 a long tail), Hooker. 

 A very singular, stove species, from the Cameroon Mountains and 

 Fernando Po, with fronds 1ft. to l|ft. long and 6in. to 9in. broad, borne on 

 firm, erect, brownish stalks 6m. to 12in. long and nearly naked. The fronds 

 are composed of a large, oblong, terminal leaflet 6in. to Sin. long and lin. to 

 ljin. broad, which is often elongated and proliferous, and of lateral leaflets 

 similar in shape to the terminal one but usually smaller, with the margin
