C. tomentosa (Poiret) Nutt., op. cit. 221 (1818) and C. laciniosa (Michx fil.) Loudon , Hort. Brit. 1: 384 (1830) are also planted on an experimental scale in Germany. They are like 3 in having large buds and angled stones, but in C. tomentosa the bark is not scaly and the twigs are tomentose for most of the summer, while C. laciniosa has pale orange twigs and 7-9 leaflets.
