P. (Dictyopteris) Brongniartii — Dic-ty-op'-ter-is ; Brong-m-ar'-ti-i 

 (Brongniart's), Bory. 

 A strong-growing, stove species, native of Malaysia and the Philippine 

 Islands. In habit it is similar to the better-known P. difforme ; but it is 

 distinguished by its small spore masses being confined to the margin of the 

 lobes. — Hooker^ Species Filicum, v., p 103. 



P. (Phymatodes) Brownii — Phy-mat-o'-des ; Brown'-i-i (Brown's), 

 Sprengel. 

 This evergreen, greenhouse species, of small dimensions, native of Australia, 

 is said by Lowe, who describes it under the name of P. attenuatum., to have 

 been introduced into England in 1823, and into the Royal Gardens, Kew, in 

 1828, by Allan Cunningham. It is a very interesting plant, with simple 

 (undivided) fronds of a dark green colour and of a very leathery texture, 

 produced from a wide-creeping rhizome of a woody nature, and clothed with 

 spear-shaped scales of a dull brown colour. These fronds are Gin. to 18in. 

 long, Jin. to Jin. broad, strap-shaped, bluntish at their summit, the lower part 

 being very gradually narrowed to a base or short stem. The large and 

 prominent sori (spore masses) are oblong in shape, and disposed in a single 

 row end to end a space from one another midway between the midrib and the 

 edge, on the upper portion of the frond, in which they are immersed. — Hooker, 

 Species Filicum, v., p. 58 ; Garden Ferns, t. 30. Nicholson, Dictionary of 

 Gardening, iii., p. 187. Lowe, Ferns British and Exotic, ii., t. 29a.

 Baker.

 It is a native of Mexico. — Hooker, Synopsis Filicum, p. 305. 



P. (Phegopteris) calcareum — Phe-gop'-ter-is ; cal-ca'-rg-um (Limestone 

 Polypody). Synonymous with P. Eobcrtianum. 



P. (Goniophlebium) californicum — Go-ni-oph-leV-i-um ; cal-if-or'- 

 nic-um (Californian), Kaulfuss. 

 This greenhouse species has a somewhat limited habitat in North America, 

 as Eaton states that "it is apparently confined to the region west of the coast
