This is a very common tree throughout the Yangtsze Valley from river-level to 

 altitudes of 1600 m. On low hills and near villages and towns it occurs as low scrub 

 or coppice, but when allowed to develop it forms a tree from 20 to 25 m. tall with a 

 trunk from 2 to 3 m. in girth. In Japan it is also abundant both as a forest tree and 

 as low scrub or coppice growth. It exhibits considerable variation in the size and 

 shape of leaves, in the length of petioles and in the degree of pubescence on the shoots 

 and on the underside of the leaves, but we find it quite impossible to distinguish 

 any variety or form. Normally the leaves on the under side have a short fasci- 

 cled, almost stellate pubescence heavily masked by long straight apjjressed hairs; 

 sometimes one or other of these forms of pubescence is absent or nearly so and com- 

 monly one or other has the ascendency. Wilson's No. 3649 from Kiating and western 

 Szech'uan has very short petioles and leaves glabrous on the under side with the 

 exception of a few long appressed hairs on the principal veins. No. 1294 from 

 Mupin is similarly glabrous, but the petioles are long and slender. No. 520 has 

 only a very sparse fasciculate pubescence. A specimen before us from a tree cul- 

 tivated in the Botanic Garden, Tokyo, has the shoots and under side of the leaves 

 densely clothed with a silky pubescence. Meyer's specimen from Shantung has 

 the leaves deeply toothed, subsessile, slightly pointed at the base and clothed 

 with appressed hairs on the under side. Maingay's specimen from the same prov- 

 ince has subsessile to short-petiolate leaves, glabrous on the under side and with 

 few very shallow teeth. Between these extremes specimens before us show every 

 gradation. The teeth are always gland-tipped and point forward and are usually 

 slightly incurved. The fruit ripens in one season and the shallow cup embraces
