glossy, dark chestnut- brown stalks oin. to Bin. long. The leaflets are closely 

 set, triangular, ^in. long and nearly as broad, the upper lobes undivided, 

 narrow-oblong, the lower ones forked or trifid (thrice- cleft), of a soft, papery 

 texture, and with both surfaces slightly hairy. The sori (spore masses) are 

 oblong. — Hooker, Species Filicum, v., p. 135. 



G. chrysophylla — chry-soph-yT-la (golden-leaved). Although usually 

 considered a species, this is a variety of G. calomelanos: 



G. (Eugymnogramme) COrdata — Eu-gym-nog-ram'-me ; cor-cla'-ta 

 (heart-shaped), Srhlechtendahl. 

 A very singular, stove 

 species, native of Cape Colony 

 and Bourbon Island, with some- 

 what egg-shaped fronds oin. to 

 Gin. long, IJin. to 2in. broad, 

 and bipinnatifid (twice divided 

 half-way to the midrib) ; they 

 are borne on black, glossy 

 stalks lin. to 2in. long and 

 more or less scaly. The leaflets 

 are oblong, with a broad centre 

 and nearly round, deeply- 

 toothed lobes, of a somewhat 

 leathery texture, the upper 

 surface of which is naked, while 

 their under -side is densely 

 coated with scales of a rusty- 

 brown colour. The sori (spore 

 masses), which are at first 

 Hnear (long and narrow), eventually become confluent and cover the greater 

 portion of the leaflets (Fig. 58). The less-divided forms resemble Asplenium 

 Ceterach in habit. — Hooker, Species Filicum, p. 131. 



G. dealbata — de-al-ba'-ta (whitened). Synonymous with G. tartar ea.
