Root four inches long, made up of round black scales, fibrous. Stem two feet high, 

 mossy at foot, smooth, and reddish brown at top; divided into three broacl leaves, two 

 opposite, and one at top, which is largest, being ten inches long, and four broad near 

 the base; variously sinuated on the edges, of a yellowish green colour, and thin. The 

 undermost pair of pinnae have ears. It grew on a shady hill on the banks of the Uia 

 Cobre.- Sloane. The large simple polypodium, with three lacerated leaves, rises com- 

 monly, to the height of twenty- four or thirty inches; its leaves are very large in pro- 

 portion, and appear as if they had. been torn at the margin. It grows in the more sandy 

 inland mountains, ami is frequent in the woods of St. Mary's. Browne.
