POLYPODIUM. 209 



The lowest leaflets are 1ft. to IJft. long and 6in. to Sin, broad ; their pinnules 

 (leafits), spear-shaped, spreading, Sin. to 4in. long, and IJin. broad, are again 

 divided into narrow egg-shaped segments bitten off on the lower side, and 

 deeply cleft on the upper one into narrow, toothed lobes. They are naked 

 on both sides, and have their spore masses disposed usually one near the base 

 of each lobe. This must not be confounded with P. sandvlcense of Hooker, 

 which is synonymous with P. stegnogrammoides. — Hooker, Species Filicum, 

 iv., p. 267. Nicholson, Dictionary of Gardening, iii., p. 193. 



P. (Phymatodes) sarcopus — Phy-mat-o'-des ; sar'-cop-us (having a fleshy 

 foot or stalk), Pe Vriese and Teysmann. 

 A stove species, native of the Celebes, with oblong, simply-pinnate fronds 

 1ft. to l^ft. long, 6in. to Sin. broad, borne on stout, naked stalks 6in. to 

 9in. long and of a fleshy nature. The strap-shaped, entire leaflets, about 

 ^in. long, are dilated at the base, of a somewhat leathery texture, and naked 

 on both surfaces. The spore masses, disposed in a single row midway between 

 the midrib and the edge of the leaflets, are immersed in a pit with a distinctly- 

 defined border, and form a much-raised, nippled surface on the upper side. — 

 Hooher, Synopsis Filicum, p. 514. 



P. sarmentosum — sar-men-to'-sum (flexible), Brackenridge. 



A small-growing, stove species, of little decorative value, seldom more 

 than Gin. high and of a somewhat leathery texture. It is a native of the 

 Sandwich Islands. — Hooker, SjJecies Filicum, iv., p. 195. 



P. Schkuhri — Schkuhr'-i (Schkuhr's). This is synonymous with 

 P. elasticum. 



P. (Phlebodium) Schneiderii — Phleb-o'-di-um ; Schnei-der'-i-i 

 (Schneider's), Schneider. 

 This may be considered the most striking and at the same time the most 

 interesting hybrid artificially raised. It originated among some seedhngs of 

 P. aiireum and P. vulgare elegantissimum, the spores of which had been 

 purposely sown together. While in a young state the oiFspring showed very 

 little diiFerence from P. aureum, but its fronds, at first entire and conspicuously 

 undulated, became more and more divided, and on the same plant one could
