30. Amelanchier Medicus View in CoL 2

Deciduous shrubs or small trees, without spines. Leaves simple, serrate. Stipules caducous. Flowers in terminal racemes, rarely solitary. Petals linear to oblong-obovate, not clawed, white, rarely pink; stamens 10-20; carpels 5, connate or partly free, with walls cartilaginous in fruit; ovules 2; styles 2-5, free or connate at base. Fruit small, 4- to 10-celled, bluish- or purplish-black, usually juicy and sweet.

This genus includes ornamental species (chiefly from North America) which flower profusely and have yellow or red leaves in the autumn. Some of these, and a few hybrids, are occasionally grown in European gardens, and their nomenclature has been very confused.
