Radula ramulina Taylor

Radulce are few and in small quantity, but include two new
and very interesting species, and (what I was particularly pleased
to see) good specimens, though sterile, of the true R. Xalapensis,
Mont., which was so-named by Montagne from a site called
Xalapa on the eastern side of Bolivia, and not from the famed
Mexican city. Radulce, like Lejeunece, are apt to grow much
mixed up, and it was doubtless a specimen of R. ramulina, Tayl.
which Gottsche received from Montagne under the name “ R.
Xalapensis ” having lurked undistinguished in the same tuft with
the true plant, and described as such in “ Mexikanske Levermos-
ser.” A stem or two of R. ramulina occurs attached to several
of Dr. Rusby’s Plagiochilce: it is well distinguished from R.
Xalapensis by its larger size, and especially by the abnormally
large and overlapping lobule, in which it closely approaches the
Irish R. voluta, Tayl.
