Abstract

Eighteen genera comprise this family, including 150 species. A single genus and species is native to Nova Scotia. Several European species are widely planted and often seen, especially in urban landscapes.Clusters of small, perfect flowers appear in early spring. The calyx has 4–9 lobes with as many stamens. Petals are absent. Leaves are simple, alternately arranged and doubly-serrate. Ours produce samaras. Elms in Nova Scotia are easily identified in leaf, as the leaf base is asymmetric on either side of the midvein. Image use provided by Marian Munro and Gerry Waldron.
