 lateil wiiii till' railiis , fcitili' ones linear-lanceolate, acntc, finely ami sharply

 scales along the niidrih. — Smith l-'hnida, 



11. WOODWARDIA, Smith. 



Fruit-dots linear-ohlong, in one or two scries on transverse anastomosing 

 veinlets parallel and near to the midrib. Indusium attached by its outer mar-

1. W. angUStifolia, Smith. Fronds smooth, jiinnatifid; the sterile ones 

 ovate, witli lii-iiadly Jaiicccilate finely serrate divisions, united at the base and

 gated areoles, each containing an oblong fruit-dot with a vaulted indusium. — 

 Bogs and shady banks. — Rootstock creeping, elongated, as thick as a goose- 

 quill. Stipe 6'- 12' high, about the length of the frond. 



2. W. Virginica, Willd. Fertile and sterile fronds alike, ovate, smooth, 

 pinnate ; piniKV lanceolate, narrowed at both ends, pinnatifid ; segments oblong, 

 obtuse ; veins forked, forming a single series of areoles along the midrib both 

 of the pinnae and of the segments ; areoles fruit-bearing in the fertile frond. 

 — Shallow ponds. — Rootstock as thick as one's finger, creeping, elongated, 

 with a tough black exterior, the interior soft and wiiite. Fronds l°-4° high ; 

 stipe smooth. 



12. CAMPTOSORUS, Link. Walkixg-Leaf. 



Fruit-dots linear or oblong, straight or curved, scattered irregularly on the

1. C. rhizophyllus, Link. Fronds evergreen, lanceolate, cordate or 

 hastate at the base, long-acuminate, often rooting at the extremity and giving

13. ASPLENIUM, L. Spleenwort. 



Fruit-dots oblong or linear, oblique to the midrib, tlie indusium attached by 

 one margin to the mostly free veins, rarely curved, or double and attached to 

 both sides of the vein. 



§ 1. AsPLENicM proper. — Indusia straight, attaclied by their whole length to 



the upper side of the vein ; rarely some of them double, and placed back 



to back. 



* Fronds undivided. 



1. A. serratum, L. Frond entire, acute, long-tapering at the base, 1°- 

 2° long, the margins wavy and serrate ; sori linear, on the lower third of the
