Resembles the last, and like that has been known to root at the tip. It is
a hybrid between the walking fern and the ebony spleenwort, as proved by
Miss Margaret Slosson, and may be looked for in the immediate vicinity of
its parents. It was discovered by R.R. Scott, in 1862, at Manayunk, Pa., a
suburb of Philadelphia, and described by him in the Gardener's Monthly of
September, 1865. Vermont to Alabama, Missouri, and southward. Rare, but
said to be plentiful in a deep ravine near Havana, Ala.

(3) GREEN SPLEENWORT. _Asplenium víride_

Fronds two to ten inches long, linear, pinnate, pale green. Pinnæ
roundish-ovate, crenate, with indistinct and forking midveins. Stalks
tufted, short, brownish below, green above. Rachis green.

Discovered at Smuggler's Notch, Mt. Mansfield, Vt., by C.G. Pringle in
1876. Found sparingly at Willoughby Lake, high on the cliffs of Mt. Horr.
This rare and delicate little plant bears a rather close resemblance to the
maidenhair spleenwort, which, however, has dark stipes instead of green.
