POLYPODIUM. 183 



P. (Phymatodes) OYatum — Phy-mat-o'-des ; o-va'-tum {egg-shaped), 

 Wallich. 

 A greenhouse species, native of Khasya, Sikkim, and Bhotan, where it is 

 said to occur up to 7000ft. elevation. It is provided with a wide-creeping 

 rhizome of a woody nature, from which the fronds, borne on firm, upright 

 stalks 4in. to Sin. long, are produced. These are 6in. to 12in. long, 2in. to Sin. 

 broad, sharp -pointed, but rather suddenly narrowed at the base ; they are of 

 a firm, papery texture, and naked on both sides. The large and conspicuous 

 spore masses are disposed irregularly in one, two, or three series. — Hooker,

P. owariense— ow-a'-ri-en'-se (Owarian). A variety of P. lycopodioides. 



P. oxylobum — ox-yl'-ob-um ( sharply -lobed). This is a synonym of 

 P. trijidum. 



P. (Phegopteris) paleaceum— Phe-gop'-ter-is ; pal-e-a'-ce-um (chaffy), 

 Powell. 

 This robust-growing, stove species, native of Samoa, has the general habit 

 of the better-known Nephrodium am.plum. Its triangular fronds, four times 

 divided nearly to the rachis and l^ft., to 2ft. each way, are borne on grey 

 stalks Ift. to 3ft. long, which, like the rachis, are clothed with narrow scales, 

 the scales becoming larger and more spreading near the base. The lower 

 leaflets, which are much the largest, are long- stalked, unequal- sided, and 

 divided into short-stalked leafits lin. to IJin. broad, wedge-shaped on the 

 lower side at the base, their final lobes being spear-shaped, ascending, and 

 bluntish. The whole frond is of moderately firm texture and smooth on both 

 surfaces, with the ribs below slightly scaly. The copious but small sori 

 (spore masses) are disposed in one row on each side of the midvein. — Hooker, 

 Synopsis Filicum, p. 505. 



P. (Phymatodes) palmatum— Phy-mat-o'-des ; pal-ma'-tum (palmately- 

 lobed), Blume. 

 A stove species, from Malaysia and the Philippines, provided with a stout 

 rhizome clothed with large, spear-shaped, dark brown scales. The fronds, 

 distinctly pinnate, and borne on firm, upright, glossy stalks 6in. to 12in. long, 

 are 6in. to 18in. long and Sin. to 12in. broad ; they are formed of a narrow-
