The recent collection of this species by native collectors for Mr. Hers 

 tends to confirm the statement made by Prantl (1. c.) that the Moutan 

 occurs wild in Kansu, though no mention is made that the specimen came 

 from wild plants. Whether the two names given to the wild plants from 

 Shensi by Pritzel and by myself represent different forms I am unable 

 to say, as I have not seen Scallan's and Giraldi's specimens and Pritzel 

 gives no description except "25 cm. alt."; Purdom's specimens are cer-
