FERN 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' long, 3'-6' wide, on a somewhat hairy stalk, ovate-lanceolate, pin- 

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

 nearly or quite to the midrib ; divisions oblique, wedged-shaped, narrow, 

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

 elongated, radiating from the base of the division. 



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

 l-3 high, thin in texture, broadly lanceolate, pinnate ; pinnae 3'-6' 

 lo'ng, lanceolate, deeply pinnatifid into close-set, oblong, and obtuse, mi- 

 nutely toothed lobes ; fruit dots 6-12 to each lobe, some of them com- 

 monly double. 



A. Fllix-fcemina, Bernh. LADY FERN. Common in moist woods ; 

 fronds large (2-3 high, 4'-8' broad), growing like the last in a crown, 

 2-3-pinnate ; pinnae 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 ; fruit dots short, variously curved, 

 at length confluent. 



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



veinlet and but one fruit dot. 



A. Belangeri, Kunze. Cult, from Malacca and Java; fronds 1-1 

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

 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, ! 9 -3 long, 6'-12' wide, 2-3-pinnate, 

 often producing leafy bulbs on the upper surface ; pinnae 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 centipede, 

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

 S. vulgElre, Smith. HART'S-TONGCE. Rare, among shaded rocks in 



Central New York, in Canada West and in Tenn. ; fronds 6'-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, WALKING LEAF. (Greek : meaning a bent 

 fruit dot.) 



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

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

 shaped or auricled base 6"-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. (Lessons, Fig. 501.) 



15. PHEGOFTERIS, BEECH FEKN (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 sessile pinnae mostly forming an irregular 



and many-angled wing along the rhachis. 



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

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