P. Phymatodes — Phy-mat-o'-des (warted), Linnceus. 



This distinct, stove species, of large dimensions, also known in gardens 

 under the name of Drynaria vulgaris, has a very wide range of habitat. We 

 find it reported as a native of Polynesia and Malaysia, also of Formosa, 

 Loo Choo, Tsus-Sima, Ceylon, the Mascarene Islands, Natal, Zambesi 

 Land, Angola, and the Guinea Coast. According to Lowe, it was introduced 

 into this country between 1816 and 1823. The fronds are produced from 

 a wide-creeping rhizome of a woody nature, and borne on firm, upright, glossy 

 stalks 3in. to 12in. long ; they are deeply pinnatifid, varying from 2ft. to 3ft. 

 in length and Iffc. in breadth, and are cut down to a broadly-winged rachis 

 into numerous entire, oblong-spear-shaped lobes 4in. to Sin. long, lin. to 

 IJin. broad, of a leathery texture, pale green in colour, shining and naked 

 on both sides. The large, circular spore masses are more or less immersed, 

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

 Filicum, v., p. 82. Nicholson, Dictionary of Gardening, iii., p. 192. Lowe, 

 Ferns British and Exotic, i., t 25. 



P. P. longipes — long'-ip-es (long-stalked),. Kunze. 



This variety, native of the East Indies, and introduced into this country 

 about 1823, differs from the typical plant by its much longer stalks and by 

 the more upright habit of its fronds, which are of an intense green colour 

 and of a glossy nature. The spore masses are usually disposed in one row 

 only on each side of the midvein ; they are oblong, of a large size, and 

 distinctly immersed in the frond, causing protuberances on their upper 

 surface. — Lowe, Ferns British and Exotic, i., t. 24. 



P. P. macrourum — mac-rou'-rum (long-tailed), Baker. 



This variety, native of Queensland, whence it was introduced into this 

 country in 1886, much resembles the species in habit and size ; it is, however, 

 readily distinguished by its long-tailed fronds, 2ft. to 3ft. long, 6in. to 12in. 

 broad, and of a bright green colour, the spear-shaped tail having its middle 

 part deeply cleft. — Nicholson, Dictionary of Gardening, iv., p. 592.
