Very abundant in forests, ascending tbe trunks of trees many yards, 

 from tbe lowest valleys up to -3.000 or 5,000 ft. alt. It begins growtb 

 on tbe ground, and at tbis stage tbe racbis is flatty winged and tbe 

 pinnae uniformly tootbed. Tbe forms are exceedingly numerous, and 

 no very clear line can be drawn between tbem. Locally tbere are two 

 states, in one of wbicb tbe pinnae are numerous (1 - IJ doz.) tbe ter- 

 minal one absent, the racbis ending in a leafless point ; in tbe otber tbe 

 pinnae are few (6 - 8) mucb broader and sborter, tbe terminal one 

 present.

Widely dispersed in woods and forests, from sea level to 4,000 ft. 

 alt. ascending tbe trunks of trees often twenty or tbirty feet. Tbe 

 fertile fronds are transient, and are only produced at seasons, so tbat 

 tbe plants are generally seen witb barren fronds only. Tbe tertiary 

 fertile pinnules are in the larger states sinuate, lobed or pinnatifid.
