Three species of deciduous shrubs closely akin to Sorbus and natives of N. America. The flowers differ from Sorbus in always having five styles; leaves always simple and with glands on the upper side of the midrib. Calyx-lobes persisting at the top of the fruit. Fruits small, red or black. They can be propagated by cuttings or by seeds, sometimes also by division. Quite hardy, easily cultivated, and handsome.

From the Supplement (Vol. V)

The genus is discussed by James W. Hardin in ‘The Enigmatic Chokeberries’, Bull. Torr. Club, Vol. 100, pp. 178-84 (1973).
