P. (Campyloneuron) Fendleri — Camp-yl-on-eur'-on ; Fend'-ler-i 



(Fendler's), Eaton. 

 This handsome, stove species, also known in gardens as Campyloneuron 

 magnificum, is a robust-growing Fern, native of Venezuela and New Granada. 

 It is provided with a stout rhizome densely clothed with large, spear-shaped 

 scales of a peculiar greyish-brown colour. Its ample fronds, borne on strong, 

 naked stalks IJft. to 2 ft. long and of a glossy nature, are furnished with 

 leaflets Ift. to l^ft. long, 2in. to 4in. broad, with edge entire, narrowed at 

 the base, and of a leathery texture ; they are of a pale green colour and 

 glossy on both sides. The spore masses are disposed in three or four rows 

 between the midvein and the edge. — Hooker, Synopsis Filicum, p. 349. 



P. (Dictyopteris) ferrugineum — Dic-ty-op'-ter-is ; fer-ru-gin'-e-um 

 (rusty-coloured), Baker. 

 A. stove species, of medium dimensions, native of New Guinea, with fronds 

 Iffc. to l|ft. long. Sin. broad, borne on stalks IJft. long, clothed densely below 

 and less so above with rusty-brown down and large spear-shaped scales of 

 the same colour. The leaflets are divided into leafits, which are again cut 

 into oblong, deeply-notched lobes of a thin, papery texture, and sprinkled 

 on their under-surface with rusty-coloured hairs. The sori (spore masses) 

 are disposed in two rows on each side of the midvein. — Hooker, Synopsis 

 Filicum, p. 318.

 young state. 



P. firmum — fir'-mum (firm), Klotzsch. 



A stove Fern, of small dimensions, native of Guiana and New Granada. 

 According to Hooker, it is scarcely more than a variety of P. rigescens, with 

 leaflets more separated. — Hooker, Synopsis Filicum, p. 335. 



P. (Niphobolus) fissum— Niph-ob'-ol-us ; fis'-sum (cleft), Baker. 



This greenhouse species, native of the Himalayas, where it occurs at 

 elevations varying between oOOOft. and 6000ft., is characterised by its strap- 

 shaped, nearly stalkless fronds, which are 6in. to 12in. long, Jin. to IJin.
