Onoclea — To close a vessel; (from the Greek.) 



Sensihilis — Sensitive. 



A J^OBLE species loDg known to Fern growers, and a very 

 desirable addition to our hardy fernery, being exceedingly 

 distinct from all others. Michaux, Sprengel, and other botanists, 

 have described two species, the second under the name of 

 Onoclea ohtusiloha. It seems doubtful whether there are really 

 two species, situation probably causing the difference in the 

 size and form of the frond. The specimens which I have seen 

 as 0. ohtusiloha, have all eventually put on the characters of 

 0. sensihilis, when grown side by side. 



A hardy deciduous species.
