A. glauceseens — glau-ces'-cens (somewhat greyish), Klotzsch. 



A stove species, native of Ecuador, Guiana, and North Brazil. Its fronds, 

 borne on slender, upright, polished stalks 6in. to 9in. long, are about 1ft. each 

 way ; they are formed of a terminal pinna (leaflet) and of several loosely- 

 spreading ones on each side, which are furnished with numerous pinnules 

 (leafits) of a thin, papery texture and about lin. long by |in. broad. Their 

 lower border is nearly straight, the upper one nearly parallel with it ; their 

 outer margin is bluntly rounded, and the lowest of these pinnules are borne 

 on short stalks. The sori (spore masses) are disposed in numerous patches 

 a line and a-half broad, with a space between them, and are situated round 

 the upper and outer edge. — Hooker, Species Filicum, ii., p. 26. 



A. glaucophyllum— glau-coph-yr-lum (grey-fronded), Hooker. 



This greenhouse species, of dwarf habit, and known in gardens as 

 A. andicolum and A. mexicanum, is closely allied to A. cuneatum, and is 

 a native of Mexico and Guatemala. Its pretty little, upright fronds, which 

 are abundantly produced from a slender rhizome (prostrate stem), are 

 seldom more than 1ft. long and 9in. to 12in. broad, quadripinnate (four 

 times divided to the midrib), and furnished with numerous segments 

 Jin. broad, deep green above and glaucous (greyish) beneath, wedge-shaped 

 at the base, their upper edge irregularly rounded and more or less lobed. 

 The reniform (kidney-shaped) sori (spore masses) are disposed in distinct 

 hollows in the summit of the upper edge. — Hooker, Species Filicum, ii., 

 p. 40. Nicholson, Dictionary of Gardening, i., p. 26. 



A. graeillimum — grac-ir-lim-um (very slender). A variety of A. cunealum. 



A. grande — gran'-de (large). A variety of A. Capillus- Veneris. 



A. grandieeps — gran'-dic-eps (large-headed). A crested variety of 

 A. cuneatum. 



A. gTOSSUm — grOs'-sum (large), Mettenius. 



In this stove species, native of the Andes of Granada, the fronds, borne 

 on black, glossy stalks Sin. to 12in. long, are lanceolate (spear-shaped), 1ft. 

 to ljffc. long, 3in. to 4in. broad, and simply pinnate (only once divided to 

 the midrib) ; the pinna? (leaflets), of a leathery texture, disposed on each
