Among the numerous species of the genus Asplenium, there is not perhaps a more decidedly
marked one than the present; for its stipes, which is longer than the frond, is almost entirely
obliterated by the singularly dccurrent margin of the latter, which, from a rather sudden contraction
near the base, gradually runs down into two winged margins to the stipes, thus forming
as it were a portion of the frond itself. The colour is a delicate pale green; the sori very numerous,
and, originating from near the costa, they reach nearly to the margin in an uninterrupted line.
The whole frond and stipes are entirely glabrous and destitute of chaffy scales.
