fronded species to which it belongs by the distinctly crenated (notched) 

 character of the margins of its spear-shaped, leathery fronds. These fronds 

 are 6in. to 9in. long and about lin. broad, sharp -pointed at their summit 

 but very gradually narrowed below. The abundant sori (spore masses) reach 

 from the midrib two-thirds of the way to the edge.— Hooker, Sjjecies Filicum, 

 hi., p. 87, t. 928. Beddome, Ferns of British India, t, 58. 



A. Hallerii — Hal-le'-ri-i (Haller's). A common garden appellation for 

 A. fontanum. 



A. (Euasplenium) Hallii— Eu-as-ple'-ni-um ; HaF-Ti-i (Hall's), Hooker. 



A very pretty, stove species, native of Ecuador and the Amazon Valley, 

 and one of the few which are proliferous (bulbil-bearing) at the extremity 

 of their fronds only. These fronds, 6in. to 12in. long and at most Sin. broad, 

 are furnished with numerous horizontal leaflets, the lower ones of which are 

 deflexed, lin. long, and peculiar in having their point bluntly rounded. They 

 are of a papery texture and dark green colour. The sori (spore masses) are 

 disposed in two rows. — Hooker, Species Filicum, hi., p. 202. 



A. Hancei — Han'-ce-i (Hance's). Synonymous with A. crinicaule. 



A. (Euasplenium) hastatum— Eu-as-ple'-m-um ; has-ta'-tum (halbert- 

 shapecl), Klotzsch. 



A greenhouse species, of small dimensions, native of Columbia and 

 Ecuador, and one which somewhat resembles A. abscissum and A. auriculatum. 

 Its fronds, 6in. to 12m. long and 3in. to 4in. broad, are borne on stalks 4in. 

 to 6in. long, firm, erect, greyish, and scaly below ; they are oblong-spear-shaped 

 and are furnished with eight to twelve pairs of subsessile pinna? (almost 

 stalkless leaflets) ljin. to 2in. long, about |in. broad, sharply pointed, with 

 their edge deeply toothed throughout and the two sides unequal ; the texture 

 is somewhat leathery. The distant sori (spore masses) fall short of both edge 

 and midrib. — Hooker, Species Filicum, hi., p. 116, t. 172. 



A. (Euasplenium) Hemionitis — Eu-as-ple'-m-um ; He-ini-on-i'-tis 



(Hemionitis), Linnaeus. 

 This very distinct, greenhouse species, perhaps the most striking of all 

 the known species with lobed fronds, is a native of Madeira, the Canaries,
