or only Exochorda /ˌɛksoʊˈkɔːrdə/[2] is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan).
Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study[1] revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss.
The leaves are paddle-shaped oval, 3–9 cm (1–4 in) long, with an entire or bluntly serrated margin.
The fruit is a dry coccetum consisting of five fused carpels, which split to release the flattened seeds.
Lemoine's catalog of 1904 [as cited by C. K. Schneider,[4] translated by Wikipedia] stated "We obtained this hybrid by fertilizing E. alberti with pollen from E. grandiflora.
