O u r conjecture at p. 1886 is so far confirmed, by the accurate
observations and kind communications of our friend Mr.
Borrer, that we can now with certainty publish this, the most
common Sussex elm, as the U. suberosa of Ehrhart (whose
specimen precisely accords with ours), and consequently of
other German writers. The late Mr. Crowe was always of
opinion that this, was the origin of all the cultivated varieties
of Dutch Elm, &c., but he was not aware of its being a native
of Britain.
The branches spread widely,- and their bark of a year old
is covered with a very dense fine sort of cork, with deep fissures.
The leaves are larger than in U. campestris, t. 1886,
more pointed, and more sharply and finely serrated. Bunches
o f flowers, which come forth in March, more hairy, and
each flower on a rather longer stalk ; its segments erect, varying
in number from 4 to 5, as well as the stamens. Fruit
rounder than in campestris, much more deeply cloven than in
montana, t. 1887, to which latter our U. suberosa appears in
most respects more akin than.to campestris, yet they are surely
all three distinct. We have now only to request some Scottish
botanist to search out U. ciliata of Ehrhart by its fringed capsule.
