Hab. Swamps, Vermont and New York, to Virginia and southwards, Michaux, 

 Pursh, Torrey, Asa Gray, etc. — Pursh's original specimens of his Woodwardia 

 thelypteroides being in ray herbarium, I can with confidence say the plant is 

 only a weak state of W, Virginica. The species is a very distinct one, and its 

 affinity rather with JV. Japo7iica than any other. The root of this seems to creep 

 extensively underground, probably after the manner of Pteris aquilina. The 

 stipes, even at the base, is in our specimens destitute of scales. 



4. W. Japonica, Sw. ; stipes with long ferruginous scales 

 at the base, frond a span to H foot long erect broad-ovate 

 subcoriaceous pinnate, pinnae lanceolate acuminate serrated 

 at their extremity sessile lobato-pinnatifid at the margin, 

 superior base truncate inferior rounded, lobes short broad 

 ovate sparsely serrate obtuse or acute, veins free towards 

 the margin, sori few oblong approximate forming two close- 

 placed lines upon the costules commencing near the cos- 

 tule of the pinnse and terminating some distance from the 

 apex of the lobe, involucres vaulted subcoriaceous, stipes and 

 rachis often paleacous with deciduous scales. — Sw. Syn. Fil.
