POLYPODIUM. 1'in 



P. (Goniopteris) rubrinerve — Go-ni-op'-ter-is ; rub-rin-er'-ve (having 

 red nerves), Baker. 

 This strong-growing Fern, native of Aneiteum and Fiji, is considered as 

 scarcely more than a variety of P. urophyllum. — Hooker, Synopsis Filicum, 

 p. 315. 



P. (Pheg-opteris) rufescens — Phe-gop'-ter-is ; ru-fes'-cens (reddish), 

 Blume. 

 A stove species, of medium dimensions, native of Java, Ceylon, New 

 Caledonia, and Queensland. Its broadly -triangular fronds, Ift. to IJft. long 

 and 9in. to 12in. broad, are produced from a short- creeping rhizome and 

 borne on firm, erect, naked stalks 1ft. to IJft. long. The lower leaflets, much 

 the largest, are deltoid (in shape of the Greek delta, A), 6in. to Sin. long, and 

 Sin. to 4in. broad, and their unequal- sided, spear-shaped leafits are bluntly 

 lobed, the lowest nearly down to the rachis. The fronds are of a somewhat 

 leathery texture and naked or slightly downy on both sides, and the spore 

 masses are disposed in one row each side of and close to the midvein. — 

 Hooker, Species Filicum, iv., p. 257. Nicholson, Dictionary of Gardening, 

 iii., p. 193. Beddome, Ferns of Southern India, t. 236. 



P. rufulum — ^ru'-ful-um (reddish). This is synonymous with P. lepidopteris 

 rufulum. 



P. rugulosum — rug-ul-o'-sum (wrinkled). A synonym of P. punctatum 

 rugulosum. 



P. (Phymatodes) rupestre — Phy-mat-o'-des ; ru-pes'-tre (rock-loving), 

 Blume. 

 A stove species, native of Java and the Philippine Islands, with fronds 

 4in. to Sin. long and lin. to l^in. broad, produced from a woody rhizome and 

 borne on firm, erect stalks 4in. to Sin. long. They are simple (undivided), sharp- 

 pointed at their summit, of a very leathery texture, and naked on both sides. 

 The spore masses are disposed in two rows between the main veins, and not 

 immersed. This must not be confounded with the P. rupestre usually met with 

 in gardens under the name of Niphobolus rupestris, which is a totally 

 different plant, and is properly known as P. serpens. — Hooker, Species Filicum, 

 v., p. 64, Nicholson, Dictionary of Gardenirig, iii., p. 193.
