pubescent petioles and often a slight pubescence on the midrib beneath, 

 and larger fruit. Meyer's original specimens are unfortunately in such 

 a bad state of preservation that it did not seem wise to take them as the 

 type of this form particularly as the pubescence of the corymb is no longer 

 recognizable on that fragmentary material.

This variety differs from the type in the generally larger ovate leaves 

 all or nearly all distinctly lobulate with short-acuminate lobules becoming 

 glabrescent in autumn and in the more brightly colored smooth fruit, 

 while in the typical form the leaves are ovate to oblong-ovate, less often 

 cordate at base, partly or mostly without any trace of lobules or less 

 deepiy lobulate, more densely tomentose beneath with more persistent to- 

 mentum; the inflorescence is usually smaller, more compact and more 

 densely tomentose and the fruit is verruculose and of duller color. As in 

 some other species of wider distribution in central China the plants from 

 Hupeh and eastern Szechuan, east of the Red Basin, though conspecifie 

 differ more or less from those from western Szechuan, west of the Red 

 Basin. In the herbarium these differences are often not so pronounced and 

 may escape notice, but when both forms are in cultivation and can be seen 

 growing side by side the differences are becoming more apparent. The 

 variety was introduced by E. H. Wilson for Veitch in 1901 and in 1907 a 

 plant was received from the Veitchian nurseries at this Arboretum. The 

 type originally described from Yunnan was found in 1908 by E. H. Wilson 

 in western Szechuan and seeds sent by him to this Arboretum were re- 

 ceived in February, 1909. Both forms have proved hardy at the Arnold 

 Arboretum and have grown into handsome pyramidal trees; as an orna- 

 mental plant the variety is to be preferred on account of its more brightly 

 colored fruit.
