FEIIN FAMILY. 495 



nate, the few divisions rather thickish, wedge-shaped or rhomboid, toothed 

 at the top ; fruit dots few, becoming confluent. 



A. furcdtum, Thunb. Cult, from Trop. Amer., S. Africa, etc. ; fronds 

 8'-15' h>ng, 3'-(i' wide, on a somewhat liairy stalk, ovate-lanceolate, pin- 

 nate with lance-oblong, acuminate pinnie, which are again pinnately cut 

 nearly or quite to the midrib ; divisions obli<iue, wedged-shaped, narrow, 

 serrate, rather coriaceous, deeply marked by the forking veins ; fruit dots 

 elongated, radiating from the base of the division. 



A. thelypteroides, Michx. In rich, rocky woods, not rare ; fronds 

 li°-3° high, thin in texture, broadly lanceolate, pinnate ; pinnee 3'-6' 

 long, lanceolate, deeply pinnatifid into close-set, oblong, and obtuse, mi- 

 nutely toothed lobes ; fruit dots G-12 to each lobe, some of them com- 

 monly double. 



A. Filix-foemina, Bernh. Lady Ferv. Common in moist woods; 

 fronds large (2°-;j" high, 4'-8' broad), growing like the last in a crown, 

 2-o-pinnate ; pinnie lanceolate, with a narrow border to the secondary 

 rhachis ; pinnules oblong and sharply serrate, or in larger plants lanceo- 

 late and pinnatifid with incised lobes ; truit dots short, variously curved, 

 at length confluent. 



* * Smallest divisions of the frond narrow, entire, containing hut a single 



veinlet and hut one fruit dot. 



A. Beldngeri, Kunze. Cult, from Malacca and Java; fronds 1^-1 J° 

 high, 2'-3' wide, coriaceous, pale green, as is the stoutish stalk ; pinnse 

 oblong, truncate at the base, with a rounded apex, pinnatifid to the 

 winged midrib into numerous narrowly oblong and obtuse lobes, the 

 upper basal ones of each pinna 2-3-cleft, the rest entire and bearing on 

 the side farthest from the main rhachis a solitary elongated fruit dot. 



A. bulbiferum, Forst. Cult, from New Zealand, etc. ; fronds herba- 

 ceous, ample, broadly lanceolate, l°-3° long, (5'-12' wide, 2-3-pinnate, 

 often producing leafy bulbs on the upper surface ; pinnie triangular- 

 lanceolate, with a broadly winged midrib ; pinnules lanceolate, deeply 

 toothed or cut into oblong-linear lobes ; fruit dots extending from the 

 middle of the lobes downward almost to the midrib of the pinnules. 



13. SCOLOPENDRIUM. (Name from the Greek word for a ce««ipe(Ze, 

 suggested by the many oblique lines of fruit each side of the midrib.) 

 S. vulgare. Smith. Hart's-tonguk. Rare, among shaded rocks in 



Central New York, in Canada West and in Tenn. ; fronds 0'-18' long, 

 l'-2' wide, oblong-lanceolate from a heart-shaped base, herbaceous, the 

 margin entire or wavy. Cultivated forms from England are crisped, 

 crested, many-forked, etc. - 



14. CAMPTOSORUS, AVALKING LEAF. (Greek : meaning a hent 



fruit dot.) 



C. rhizophyllus. Link. Damp, mo.ssy rocks, N. , and S. mainly along 

 the mountains ; frond evergreen, 4'-12' long, tapering from a heart- 

 shaped or auricled base 0"-12" wide to a long, narrow point, which often 

 roots at the end, and there gives rise to a new plant, ready to take 

 another step in advance. (Le.ssons, Fig. 501.) 



15. PHEGOPTERIS, BEECH FERN (which the name means in 

 Greek, the original species often found among beeches). Chiefly tropi- 

 cal, but the following are all wild species, in rocky or shady woods. 



* Fronds twice pinnatifid ; the sessil e pinnce mnstln forming an irregular 



and hianij-angled wing along the rhachis. 

 P. polypodioides, F6e. Common N. ; fronds 4'-9' long, longer than 

 broad, triangular-ovate, slightly hairy beneath ; pinnaj lanceolate, the
