A. flexuosa— flex-u-o'-sa (wavy). Synonymous with A. tomentosa. 



A. fraxinifolia— frax-in-if-oF-i-a (Ash-leaved). A variety of A. Phyllitidis. 



A. Gardneri— Gard'-ner-i (Gardner's), Hooker. 



This pretty, stove species, native of South Brazil, and also known in 

 gardens -as A. Glaziovii, must not be confounded with A. Gardneriana of 

 Presl (synonymous with A. glareosa of Gardner), also from South Brazil, 

 but from which it is totally different. Its fronds, of a leathery texture, and 

 with rachis (stalk of the leafy portion) and both surfaces naked, are borne 

 on firm, upright, and equally naked stipes (stems) Sin. to 4in. long. Their 

 barren portion, 4in. long by 2jm. broad, is formed of four pairs of imbricated 

 pinnae (overlapping leaflets), the lowest of which are about lin. broad : they 

 are all borne on short footstalks, and have their veins quite flabellate (fan- 

 shaped), and their edge conspicuously notched with little, roundish teeth. 

 The fertile portion of the frond, which is situated at the base of the barren 

 one, consists of contracted segments disposed in a panicle about Sin. 

 long, and is borne on a stalk of about equal length.— Hooker, Synopsis 

 Filicum, p. 431. 



A. Gardneriana— Garcl-ner-i-a'-na (Gardner's). This is identical with 

 A. glareosa. 



A. glareosa— gla-re-o'-sa (growing in gravelly places), Gardner. 



This stove species, native of South Brazil, is remarkable owing to 

 its barren portion being truly pinnate (once divided to the midrib) only at 

 the base, as also by the rusty-coloured hairs with which the firm, upright 

 stipes (stalks) are densely clothed. It is also known as A. Gardneriana. 

 The fronds, of a leathery texture and with both surfaces finely hairy, have 

 their barren portion formed of a terminal lobe and of three or four pairs of 

 oblong, blunt pinnae (leaflets), only the lowest pair, which are occasionally 

 lobed on the lower side at the base, being divided to the midrib. The fertile 

 portion, formed of dense, short, somewhat upright branches of contracted 

 segments disposed in a panicle 3in. to 4in. long, is borne on a footstalk 

 seldom exceeding lin. in length. — Hooker, Synopsis Filicum, p. 432. 



A. GlaziOYii— Glaz-i-o'-vi-i (Glaziou's). Synonymous with .4. Gardneri.
