At first sight, and with the eye unaided by a microscope, this plant has very much the appearance ,
of Trichomanes lanceum; but a more careful examination will show it to be very distinct, even as
to its genus : the involucrum here being completely th a t of a Hijmenophyllim, and the margin wants
the cilia? of that plant,—being furnished instead with a thickened margin.
We have only received specimens from Mr. Fraser, gathered in New Holland, and, we believe, in
the neighbourhood of Port .Taekson.
