POLYPODIUM. 143 



P. (Phymatodes) glaucum — Phy-mat-o'-des ; glau'-cum (bluish-green), 

 Kunze. 



This stove species, which in texture and general habit resembles some 

 forms of P. aureum, is a native of the Philippines. Its bluish fronds, 1ft. to 

 IJft. long and 6in. to Sin. broad, borne on firm, erect stalks 6in. to 12in. long 

 and of a glossy nature, are produced from a stout rhizome clothed with long, 

 narrow scales of a dark brown colour. They are cut down throughout to 

 a broadly-winged rachis into entire, sharp-pointed lobes 4in. to oin. long, 

 of a leathery texture, and naked on both sides. The sori (spore masses) 

 are disposed in single rows close to the midrib. P. glaucum of gardens is 

 identical with P. aureum sporadocarpum.-— Hooker, Species Filicum, v., p. 88. 



P. (Goniophlebium) gonatodes — Go-ni-oph-leb'-i-um ; gon-at-o'-des 

 (angled). This is synonymous Avith P. plesiosorum. 



P. gracile — grac'-il-e (slender), Hooker. 



A pretty, stove species, native of the Andes of Peru, with flaccid, pendent 

 fronds 6in. to Din. long, barely lin. broad, borne on slender, tufted stalks 

 Sin. to 4in. long and of a wiry nature. The leaflets, though scarcely Jin. 

 long, are distinct and deeply cleft into blunt lobes bearing one spore mass 

 each. — Hooker, Species Filicum, iv., p. 224. Hooker and Greville, Icones 

 Filicum, t. 222. 



P. (Grammitis) gramineum— Gram-mi'-tis ; gra-min'-e-um (grass-like), 

 Swartz. 

 This stove species, of purely botanical interest, is very distinct through 

 its leathery fronds, 2in. to 4in. long, being only Jin. broad, and also on account 

 of the oval or oblong spore masses being placed nearly end to end, with 

 a space between them, in two rows which reach from the midrib nearly to 

 the edge. It is a native of the West Indies and Guiana. — Hooker, Species 

 Filicum, iv., p. 165. 



P. grammitidis — gram-mi'-tid-is (Grammitis-like), R. Brown. 



A greenhouse species, of small dimensions, native of New Zealand and 

 Tasmania, with fronds 4in. to 12in. long, 2in. broad, borne on tufted, naked 

 stalks lin. to 2in. long and of a wiry nature. The narrow, blunt leaflets are
