Hi Paul & All,
Native Trees of Canada, 1961, Dept of Forestry lists only three=20
elms, Ulmus americana, U. rubra (Slippery Elm) and U. thomasii (Rock=20
Elm). In all three species the leaf blade is asymmetric on the petiole;=20
starting lower on one side than on the other and this is least evident=20
in rock elm. For clear ID you will need the fruit and remnants might=20
still be found on the ground. Only U. americana is native here. Slippery=20
Elm is sometimes planted as an ornamental I think.
Yt, DW, Kentville
