are narrower and the petioles and young branchlets puberulous. The 

 specimens from Honan are all sterile and agree well with Wilson's no. 1441 

 from Hupeh doubtfully referred by Schneider to S. paraplesia, but Hers' 

 nos. 968 and 1251 are furnished on the underside of the leaves with 

 scattered appressed silky hairs and, while the original specimen of 1441 

 shows no trace of pubescence, plants cultivated in the Arnold Arboretum 

 under Wilson's no. 1441 have the midrib beneath and the young branchlets 

 often slightly pubescent.
