526 WILSON EXPEDITION TO CHINA 



The simple inflorescence well distinguishes this species from the closely related 

 M. japonictis Miiller Arg., which has a branched paniculate inflorescence. All the 

 Bpecimens I have seen from Hupeh and Szech'uan belong to Pax^s species and very 

 probably the Japanese species does not occur in that region. 



This is a very common roadside bush or small tree in western Hupeh and Sze- 

 ch^uan, being particularly abundant in warm rocky valleys. E. H.W.
