c. From Hang-Chow, China. 



Received from Thos. Hanbiu-y as the tree yielding the 

 spice called Haw-tseaou, Oct., 1856. To specimen (c) two 

 letters are attached, one from Dr. Hooker, and another from 

 Alphonse De Candolle. The former letter has a note attached 

 in Daniel Hanbiiry's writing, to the following effect : — 



"Subsequent comiiarison with a large suite of specimens from the 

 Kew Herbarium, as well as specimens from the Herbarium of the 

 Linnean Society, fully confirmed Dr. Hooker's opinion that the Ilaiig- 

 Chow plant is Xanthoxylum alatum, Roxb." 



In the other letter De Candolle states that he has compared Hanbury's 

 X. alatum with Xanthoxylum acanthopodimn, D.C., and that the latter 

 is very different, having imparipinnate leaves with 9 leaflets, not 

 ternate, the rachis more narrowly winged, the leaflets longer, more 

 gradually attenuated above, and generally long thin spines ("aculeole.s") 

 on the middle side. The secondary ones are more closely approxi- 

 mated, more numerous, more prominent, and the leaflets are pubescent 

 on the secondai-y veins. The length of the leaf Ls 7—8 inches. The 

 spines of the rachis are more veined.

n. Leafy stem. 



Garden, Clapham Common, 7 Aug., 1866. Raised from 

 seed received from Pekin.
