bany 1833, where it was wrongly ascribed to O. Clay- 
toniana. Prof. Alphonso Wood in early editions of 
“A Class-Book of Botany,’ also describes it under 
the name O. Claytoniana and refers to the Cambridge 
plants: but Dr. John Torrey, in his “A Flora of the 
State of New York” 2: 503. 1843, describes it as the 
var. frondosa, and says it has been found near Cam- 
bridge (Dr. M. Stevenson), as well as at Stillwater 
(Dr. Fitch). Dr. Stevenson’s Cambridge specimens 
were preserved in an old collection at the N. Y. State 
Herbarium. 
The form incisa (Huntington) Gilbert, with the 
sterile pinnae more or less incised, has been found at 
Hampton (F. G. Taylor), Aug. 31, 1908; the woods 
southeast of Oneida, near Halfway brook; and east of 
Tripoli. At Tripoli some of the plants approached 
f. bipinnatifida Clute. 
OsmUNDA CLAYTONIANA L. 
Often growing Msg the preceding fern: and about as 
common. May-Jun 
The form pusta (Grout) Clute has been met with 
east of Tripoli. The sterile pinnae take the place of 
the fertile ones; on the edge of which, imperfect spor- 
angia were visible: and the pinnae were more incised 
than usual.

This fern siodunis two kinds of fronds; the sterile 
are triangular and herbaceous, quickly baraink black 
after the first frosts. The fertile are much contracted, 
with berry-like segments and persist until the following 
' spring. Vi asiins with the ect rather Bred cut
