very closely and regularly in a single oblique row extending from the 

 midrib nearly to the edge of each fertile pinna, where they eventually become 

 confluent. — Hooker, Species Filicum,, hi., p. 115. Nicholson, Dictionary of 

 Gardening, i., p. 128. Eaton, Ferns of North America, ii., p. 73, t. 56.

A. (Euasplenium) angustum — Eu-as-ple'-ni-um ; an-gus'-tum (narrow), 



Swartz. 



Although the name of this species is somewhat similar to that of the 

 two just described, the plant is totally different, for its fronds are quite 

 entire (undivided) ; they are of a somewhat leathery texture, 1ft. to 2ft. 

 long, ljin. broad, and borne on short, tufted, erect stipes (stalks) of a greyish 

 colour ; their extremity is much acuminated (ending in a long, tapering 

 point) and their margin nearly smooth. The rather distant sori (spore 

 masses) reach from the midrib nearly to the edge, in an oblique direction. 

 This plant, being a native of Brazil and Guiana, requires stove treatment.

A. (Euasplenium) anisophyllum — Eu-as-ple'-ni-um ; an-is-oph-yr-lum 



(unequal-leaved), Kunze. 

 A greenhouse species, of large dimensions, native of Cape Colony and 

 Brazil, and one which is easily recognised by the tumid involucres (swollen 

 coverings) of its spore masses. Its fronds, oblong- spear- shaped, 1ft. to 2ft. 

 long and 6in. to 9in. broad, are borne on tufted, firm, erect stipes (stalks) 

 6in. to 12in. long and scaly below ; they are only once divided to the 

 midrib, which is furnished on each side with from ten to sixteen sub-sessile 

 pinnae (almost stalkless leaflets). The pinnae are nearly horizontal, 3in. to 

 5in. long, barely lin. broad, and terminate in a tapering point ; they are of 

 a soft, papery texture. The short and regular sori (spore masses) are 

 distant, elliptical, and do not reach more than half-way from the edge to 

 the margin of the fertile pinnae. — Hooker, Species Filicum, hi., p. Ill, t. 166.

A. (Euasplenium) apieidens — Eu-as-ple'-ni-um ; ap-ic'-id-ens (toothed 

 at the apex). A variety of A. Vieillardii.
