This is a very common shrub in thickets and on cliffs in western Hupeh and in 

 Szech'uan and very variable in size of leaf, in length of raceme and in the number 

 of flowers on the raceme. In No. 3201 the shoots terminate in from 1 to 3 racemes 

 but in all the other Chinese specimens before us the raceme is solitary. We have 

 not seen Polygala fallax Hemsley (in Jour. Linn. Soc. XXIII. 59 [1886]) nor P.
