truncate or rounded base, acuminate, nearly entire 1 ; those of the fertile frond 

 narrower; fruit-dots slightly curved, very numerous. 



4. Frond* niori' than 

 * fruit-dots more than one in each smallest dicision of the frond. 



A. Rilta-muraria, WALL-RUE. On e\po-ed dills of lime-tone, from 

 Vermont W. & S. : fronds small, l'-4 long, ovate, twice or thrice pinnate, 

 the few divisions rather thicki.-h, wed-e-.~liaj.ed or rhomboid, inutlicd at the 

 top ; fruit-dots few, becoming coidlnent. 



A. furcatum. Cult, from Trop. Ameriea, S. Africa, &c. : fronds 8'- l.V 

 long, 3'- 6' wide, on a somewhat hairy stalk, ovate-lanceolate, pinnate with 

 lance-oblong acuminate pinnae, which are again pinnately cut nearly or quite to 

 the midrib; divisions oblique, wedge-shaped, narrow, serrate, rather coriaceous, 

 deeply marked by the forking veins ; fruit-dots elongated, radiating from the 

 base of the division. 



A. thelypteroides. In rich rocky woods, not rare : fronds U-3 high, 

 thin in texture, broadly lanceolate, pinnate; pinna; 3'-G' long, lanceolate, 

 deeply pinnatitid into close-set oblong and obtuse minutely toothed lobes ; fruit- 

 dots 6-12 to each lobe, some of them commonly double. 



A. Filix-fcernina, LADY-FERN. Common in moist woods : fronds lar-.' 

 (2-3 high, 4'-s' broad), growing like the last in a crown, 2-3-pinnai ; 

 pinnae lanceolate, with a narrow border to the secondary rhachis : pinnules 

 oblong and sharply serrate, or in larger plants lanceolate and pinnatitid with 

 incised lobes ; fruit-dots short, variously curved, at length continent. 



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



and but one fruit-dot. 



A. Belangeri. Cult, from Malacca and Java: fronds l-l hiuh, 

 2' -3' wide, coriaceous, pale green, as is the stoutish stalk ; pinna; oblong, 

 truncate at the base, with a rounded apex, pinnatitid 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. rn.yrioph.yllu.ni. Limestone caves in Jack-on Co., Florida : fronds 

 delicate, almost translucent, lanceolate, 0'-!)' long, l'-2' wide, 2-3-pinnate; 

 smallest divisions obovate-oblong, 2"-3" long, ^" wide ; fruit-dot in the lower 

 half of each division. 



A. foulbtferum. Cult, from Xew Zealand, &c : fronds herb-iceoii-. ample, 

 broadly lanceolate, l-3 long, C'-12' wide, 2-3-pinnate, often producing 

 leafy bulbs on the upper surface; pinine 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. 



12. SCOLOPENDRIUM. (Name from the. Greek word for a <;;,ti,,,,l,; 

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



S. VUlgare, HART'S-TON<;UE. Rare, amon-r shaded rocks in Central New- 

 York and in Canada West ; fronds G' - 18' long/ 1 ' - -'' wide, oblong-lanceolate 

 from a heart-shape,! base, herbaceous, the margin entire or wavy. Cultivated 

 forms from England are crisped, crested, many-forked, jLc. 



13. CAMPTOSORUS, WALKING-LEAF. ( Xame from the Creek, 

 meaning a ben/ heap, referring to the curved and angled fruit-dot.-.) Aliuo-t 



the only species is 



C. rhizophyllus. Damp mossy rock- X. ,^ S., mainly along the moun- 

 tains: frond 4'- 12' long, tapering from a heart-shaped or aui d ha- 

 wide to a long narrow point, which often ro:>ts at the end, and there gives rise 

 to a new plant, ready to take another step in advance. (Lesions, \]^. 501.) 



14. PHEGOPTERIS, BEECH-FERN (which the name means in Greek,
