THE BOTANICAL JOURNAL OF G. W. CLINTON - May 1865

[1865.] May 1. To date, this spring, have collected & had identified
by Mr. Peck 15 mosses & one Liverwort.

The elm in the barn yard, going from the Williamsville road to the
entrance of the Gun [?] is Ulmus racemosa. At any rate the flowers are
racemed, though I can discover no sign of corkiness on bough or branch.

[Ulmus racemosa Thomas is Ulmus Thomasi Sargent, according to House,
1924). The Rock Elm has older twigs that are often irregularly winged
with plates of cork.]

I want to know the history of Ulmus thomasii and its synoname (we
should spell this word this way) Ulmus racemosa. Mr Thomas was a
engineer circa 1901 so how did his name become attached to a species of
elm tree which was highly harvested in the 1800's and before Mr. Thomas
was alive.

So was there no Rock elm in Europe until it was exported in the 1800s
to Europe and did the Europeans then classify it as Ulmus racemosa

Seems like the history of naming this species of elm is Historic
contortedata (pun intended)
