This elegant, yellow Rose was raised at Kew from 
seeds received, with others, from the Keeper of the 
Botanical Department of the British Museum, in 1899, 
They were collected by Father Hugh (otherwise Pater 
Hugo) Scallan, a Catholic missionary, in Western China, 
probably in the Province of Shensi or Szechuen. It is 
apparently quite hardy at Kew, flowering freely in the 
open air. wae 
Exception may, perhaps, be taken to its being treated 
as a distinct species; but as it certainly deserves a dis- 
tinctive name, it seems better to give it one, without 
tacking it on to any other. The late Prof. Crépin would 
probably have referred it to ‘‘ A. eanthina, Lindl.,” with 
which he associated [. platyacantha, Schrenk, and f#. 
Ecx, Aitch. Although Sir Joseph Hooker (B. M. t. 7666), 
and the late Mr. Franchet (Nouv. Arch. du Mus. Par. 
série 2, vol. v. p. 269, t. 15, f. 2) have followed Crepin, 
Marcu Ist, 1905.
