Origin
Europe

Ulmus × hollandica 'Dauvessei' is a very rare cultivar of unknown provenance. The branches ascend to form a broad, pyramidal crown; the leaves bear a vague resemblance to Wych Elm, but are generally smaller, rarely exceeding 10 cm long by 5 cm wide, and thinner in texture ^[1]. It was once grown at Kew Gardens where it attained a height of 13 m ^[2].

'Dauvessei' is not known to have been introduced to North America.

[edit] Hybrid cultivars

'Dauvessei' was crossed with Ulmus × hollandica, U. glabra and U. minor subsp. minor in the Dutch elm breeding programme before WW2, but none of the progeny were of particular note and were discarded. ^[3]
