A fern, so far as I know, peculiar to the two localities above 
mentioned. It is remarkable for the narrow and very tapering 
willow-like pinne of the frond, certainly in the specific 
character as given by Willdenow, of M. angustifolium, (“ fron- 
dibus pinnatis pinnis lineari-lanceolatis acuminatis integer- 
rimis, basi angustatis,)” a near ally of that species; but that 
is a native of South America, from Caracas, and the whole 
height of the frond is described to be nine inches, the pinne 
three inches long, the stipes 2-3 inches: whereas our plant 
is 2-3 feet long, the pinna 8-9 inches in length, the stipes 
more than nine inches. Each transverse veinlet bears two 
oval sori which soon become confluent.
