Although reported to be essentially glabrous, a hairy ovary summit is characteristic of the fruit of Amelanchier lucida, and this helps to explain some of the variation in its taxonomic treatment by recent authors. In many instances plants would have been identified as A. stolonifera. Flowering material is here described for the first time. The erect racemes have lower pedicels 8–22 mm long, and petals are 6–7.5 mm long and 2.5–3.3 mm wide. At flowering, the leaves are tomentose but towards the end of flowering the thick tomentum is lost from the outer surfaces of the sepals and the larger leaves. Stoloniferous habit, glossy leaves, ascending sepals, and pubescent ovary summit are a distinctive combination of features of A. lucida. A key to the stoloniferous species of Amelanchier in Nova Scotia is included.
