sun or shade in peaty soil or leaf mold. Its usual habitat being swamps and 

 borders of streams. 



Lvgodium palmatum. (Climbing Fern). Three to six feet long. Pinnae 

 roundish, five to seven lobed. Grows in swamps near the Atlantic seaboard, 

 twining about the bushes, usually in half shade. Rootstock slender, creeping. 



Onoclea sensibilis. (Sensitive Fern). vSterile fronds one to three feet high. 

 Broadly triangular, ovate, nearly pinnate. Fertile fronds produced late in the 

 season, the divisions rolled up into berry-like objects. Both kinds of fronds 

 from a creeping rootstock, the sterile produced all summer. Will grow in any 

 soil, in sun or shade, its natural home being the borders of streams, swamps, 

 and wet woodlands. 



O. Struthiopteris. (Ostrich Fern). Our tallest Fern, one to ten feet high, in 

 a crown of twenty or more fronds. Sterile fronds twice pinnatifid, oblanceo- 

 late in outline. Fertile fronds produced late in the season, their divisions rolled 

 up much as in O. sensibilis. Banks of streams and wet open woods in sandy 

 soil or leaf mold. Will stand sun all day, but grows best in partial shade, at 

 least. Spreads by offsets at the ends of long runners. 



Osmunda Clay^oniaaa. (Interrupted Flowering Fern. Clayton's Fern). 

 One to four feet high. Bi-pinnatifid. Fronds in crown of six to twelve, from 

 a very thick rootstock in early spring. Fertile fronds, have part of the middle 

 of the frond turned to spore-bearing organs. Found in swamps and pastures. 

 Will stand sun or shade, but requires rather rich soil. 



O. cinnamotnea. (Cinnamon Fern). One to five feet high. Fronds in large 

 crowns in early spring from an exceedingly heavy rootstock; bi-pinnatifid. 

 Fertile fronds produced in early spring, from the midst of the sterile, but im- 

 like them are short, thick, club-shaped, the green portion changed to myriads 

 of little spore cases, of a bright brown color when ripe. Will stand sun or 

 shade, if the soil is wet. Grows naturally in swamps, pastures, and low 

 grounds. 



0. regalis. (Royal Fern. Flowering Fern). One to six feet high. 

 Twice pinnate, the pinnules usually orbicular. Fronds in circular clumps from 

 a very thick, stout, erect rootstock. Fruiting panicle at the end of the fronds. 

 Will grow in sun or shade. Its natural habitat is swamps and wet woodlands, 

 where it is often found growing in shallow water; will grow also in drier situ- 

 ations. Fronds in spring and early summer. 



Pliegopteris Dryopteris. (Oak Fern). Three to twelve inches high. Frond 

 ternate (like three Ferns in one), the division stalked and bi-pinnate. Root- 

 stock creeping and producing fronds all summer. Moist rich places in shade 

 only. 



P. Pliegopteris. (Beech Fern). Three to ten inches high. Fronds 

 triangular, nearly twice pinnate. Rootstock running; fronds all summer. 

 Damp woods, usually in stony soil in rich earth. Does not endure the sun. 



Pteris aqvilina. (Bracken, Brake, Eagle Fern). One to six feet high;
