P. 1. latipes — la'-tip-es (broad-footed), Langsdorff and Fischer. 



This variety, which in gardens is frequently found under the names of 

 P. Catherines, P. harp codes, and P. vacillans, is very distinct from the species. 

 Its much larger fronds are slenderer and of a pendulous habit, though of 

 a texture similar to those of P. loriceum ; their leaflets, much enlarged on both 

 sides at the base, are of a dull green colour on both sides, and the small, 

 yellowish sori (spore masses) are disposed in one distinct and regular row on 

 each side of the midvein. It is a native of Brazil and St. Catharine, and, 

 according to Lowe, was introduced into the Royal Gardens, Kew, in 1841.

P. (Campyloneuron) lucidum — Camp-yl-on-eur'-on ; lu/-cid-um 

 (shining), Bory. 



A very distinct, stove species, of small dimensions, native of Venezuela 

 and Brazil. Its short- creeping rhizomes produce fronds Gin. to 12in. long, 

 fin. to fin. broad, narrowed to both ends, of a rigid texture, and very glossy 

 on both sides. The sori (spore masses) are not very abundant ; they are of 

 a pale yellow colour and are confined to the upper part of the frond. 

 P. nitidum is synonymous with this species. — Hooker, Species Filicum, v., 

 p. 41. Nicholson, Dictionary of Gardening, iii., p. 191. 



P. (Phymatodes) lycopodioides— Phy-mat-o'-des ; lyc-op-od-i-o-i'-des 

 (Lycopodium-like) , Linnaeus. 

 This very dwarf, but exceedingly pretty, stove species, native of the 

 West Indies and Tropical America, was, according to Lowe, introduced into 

 the Royal Gardens, Kew, in 1821. Its simple (undivided) fronds, produced 

 from a wide-creeping rhizome, are of two kinds, and either short -stalked or 

 stalkless. The barren ones, Sin. to 4in. long and Jin. to lin. broad, are often 

 blunt and gradually narrowed at the base, while the fertile ones are longer 

 and narrower. Both kinds are of a leathery texture and of a shining nature, 

 and the spore masses are disposed in one row along their margins. This 

 species is also known as P. venosum. — Hooker, Synopsis Filicum, p. 357.
