 Sept., 1867. From Prof. Dr. J. E. Planchon. 

 c. Twig in fruit. 



Pekin, W. G. Stronach, 1862. 



This specimen is accompanied by a letter from M. Stronach 

 in which he says the plant is called at Pekin, Hwa- 

 chieao. A note in pencil by D. H., states— Mr. 

 Bennett would call this " X piperitum." [The fruit of 

 X. piperitum in the Hanbury Materia Medica collection 

 dififers from this specimen in being reticulated and 

 without raised tubercles. 



89. Xanthoxylum piperitum, D.C, 



Clapham, cultivated in the garden, 1 Oct., 1864. 



This specimen has only the flowers, but is accompanied by 

 a pen and ink sketch of the young fruit. 

 [Note. — The fruit of X. alatum Ls covered with small, raised, scattered 

 tubercles, which are apparently oil glands. These are more sbusdant 

 and crowded in X. Bungei. The fruit of X. piperitum in the Hanbury 

 Collection of Materia Medica differs from both these in having a 

 reticulated surface, in which the oU glands appear to be sunken. Mr. 

 Stronacli's specimen has crowded tubercles like the other specimens of 

 X. Bungei. It is not apparent, therefore, why Hwa-tseaou is stated in 

 'Science Papers,' p. 228, to be applied to the fruits of "the two species of 

 Xanthoxylum," viz. : X. piperitum, D.C, and X. alatum, Roxb., since 

 from the Herbarium specimens above enumerated it would seem that 

 fruits of X. alatum are used in Hang-Cliow under the name of Hwa- 

 tseaon, and those of X. Bungei under the .same name in Pekin.]
