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 

 l^ft. long and 6in. to Sin. broad, borne on firm, erect stalks Bin. 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 5in. 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 with P. plesiosorum. 



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



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

 fronds Bin. to 9in. long, barely lin. broad, borne on slender, tufted stalks 

 3 in. to 4in. long and of a wiry nature. The leaflets, though scarcely £in. 

 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 ; gTa-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 |dn. 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
