A. (Euasplenium) magellanicum— Eu-as-ple'-m-um ; mag-el-lan'-ic-um 

 (from Magellan), Kaulfuss. 

 A greenhouse species, of small dimensions, much resembling our common 

 Wall-Rue (A. Ruta-muraria), but with fronds more compound ; their second 

 divisions or pinnules are again cut down into spathulate (spoon- shaped) 

 segments slightly dented round the edges, and the son (spore masses) are so 

 copiously disposed as to entirely cover the under -surface of the pinnules. It 

 is a native of Temperate South America. — Hooker, Sjiecies fflUeum, hi., p, 177. 



A. (Darea) Mannii — Da'-re-a ; Man'-m-i (Mann's), Hooker. 



A greenhouse species, of very diminutive dimensions, seldom exceeding 

 2in. in height. It is a native of the Cameroon Mountains, Fernando Po, and 

 Zambesi Land. — Hooker, Second Century of Ferns, t. 60. 



A. (Hemidictyum) marginatum— He-mid-ic'-ty-um ; mar-gm-a'-tum 

 (margined), Linnaeus. 

 This stove species, one of the most gigantic of the whole genus, is 

 a native of Tropical America, its habitat extending from Cuba and Venezuela 

 to Peru and Brazil. Its robust fronds, 4ft. to 6ft. long and 2ft. to 4ft. broad, 

 are borne on strong, erect, woody stalks 2ft. to 3ft. long and sometimes Jin. 

 thick at the base, and are simply pinnate (only once divided to the midrib), 

 their leaflets being disposed in several opposite pairs. The lowest of these 

 leaflets are from lft. to 2ft. long and Sin. to 4in. broad, have their edge 

 entire and their base often heart-shaped, and are of a thin, papery texture. 

 The long and narrow sori are disposed on the free veins only. — Hooker, 

 Species Filicum, iii., p. 271. Nicholson, Dictionary of Gardening, i., p. 132.. 



A. (Euasplenium) marinum — Eu-as-ple'-ni-um ; mar-i'-num (Sea 

 Spleenwort), Linnceus. 

 This greenhouse species, which, as its name implies, grows naturally by 

 the seaside, is of a very cosmopolitan character, as besides being a native of 

 the British Islands it is also indigenous in the South of France, Spain, the 

 Canary Islands, Madeira, TenerifFe, the Azores, and the Northern parts of 

 Africa, in all of which places it is tolerably abundant. It is, however, as 

 a British plant that it is most interesting, and it is sad to have to record
