Hab. Natal, ^rau,ss, 25. — Very near ^. viride, of which it maybe a form, but the

28. A. fragile, Presl ; 5^. tufted, 2-4 in. 1., slender, flexuose, green or brownish, 

 sometimes gemmiferous ; fr. 6-9 in. 1., ^-h in. br., with 12 to 20 sessile pinnce on

Hab. Along the Andes from Mexico and Peru. — A. rhomhoideum, Brack., which 

 grows also in the Sandwich Islands, has fronds 12-18 in. 1., with pinnae not so dimidiate 

 and often dfeply lobed on the upper side near the base. Tliis also comes very near
