POLYPODIUM 195 



P. p. ciliatum — cil-i-a'-tum (fringed), Willdenow. 



The distinguishing feature of this variety resides in the peculiar character 

 of the fertile fronds, which are so narrow that the spore masses project beyond 

 their margins. — Hooker^ Synopsis Filicum, p. 340. Nicholson, Dictionary of 

 Gardening, iii., p, 192. 



P. platybasis — plat-yb-a'-sis (having a broad base). Baker. 



In this stove species, of small dimensions and of little decorative value, 

 native of Salta, in the Andes of Peru, the bipinnate (twice-divided) fronds, 

 produced from a rhizome as thick as a quill, have their leaflets deeply notched, 

 of a leathery texture, and dark dull green in colour, and their leafits suddenly 

 enlarged at the base. The spore masses occupy the whole space between 

 the midrib and the edge. — Hooker, Synopsis Filicum, p. 511. 



P. (Goniophlebium) platylepis — Go-m-oph-leb'-i-um ; plat-yl'-ep-is 

 (broad -scaled), Mettenius. 

 A small-growing, stove species, of purely botanical interest, having a 

 rhizome clothed with conspicuously large, spear-shaped scales of a pale brown 

 colour. It is a native of Guatemala and New Granada. — Hooker, Synopsis 

 Filicum, p. 512. 



P. (Phegopteris) platylotaum — Phe-gop'-ter-is ; plat-yl'-ob-um (broad- 

 lobed), Baker. 

 This strong-growing species, native of Tarapota, North-East Peru, produces 

 fronds 2ft. to 3ft. long, 1ft. or more in breadth, born on firm, upright stalks 

 1ft. to IJft. long, and scaly towards the base. The central leaflets, 6in. to 

 Sin. long and lin. to IJin. broad, are cut down to the rachis in the lower 

 part into blunt, oblong lobes, and their lower leaflets are slightly reduced. 

 The fronds are of a soft, papery texture, and almost naked on their under- 

 side ; the spore masses are situated almost on their margins. — Hooker, Species 

 Filicum, iv., p. 238. 



P. (Phymatodes) platyphyllum — Phy-mat-o'-des ; ' plat-yph-yl'-lum 

 (broad-leaved), Swartz. 

 This is a very striking and distinct, stove species, of medium dimensions, 

 native of Java. Its entire (undivided) fronds, 1ft. to IJffc. long and 2in. to
