Radula aquiler/ia, Tayl., differs in the dark olive-brown colour,

Radula Limlhen/ia}ia, Gottsclie, comes near to it, but differs in 

 being of a laxer texture ; colour sordid green or brown ; insertion 

 of leaves, wliicli stand off" from the stem, not so closely imbricating; 

 colesule shorter and broader. 



ANOTHER NEW CHINESE RHODODENDRON. 

 By H. F. Hance, Ph.D., F.L.S. 



I HAD the pleasure of describmg, in the pages of this Journal 

 last year,''' a very fine new species of Rhododendron, discovered in 

 Kwang-tung province by the Eev. B. C. Henry, of the American 

 Presbyterian Board of Missions. Mr. Henry lately again visited 

 the locality, and was successful in procuring several vigorous living 

 specimens of this desirable shrub, which I have little doubt will 

 soon be in cultivation in Europe. He was still more fortunate in 

 detecting another extremely beautiful species, also undescribed, of 

 wliicli he brought back living branches in full flower, enabling me 

 to draw up the following diagnosis from the most satisfactory 

 materials. I have dedicated it to Mr. Henry's amiable and accom- 

 plished wife, the frequent companion of his missionary journeys 

 into the interior, who on these occasions has the charge and 

 preparation, ex officio, of the botanical collections, a task for which 

 the excellently dried specimens prove her to have been specially 

 designed by natural selection.

This unquestionably belongs to the group Tsusia, but is remark- 

 ably distinct from all its allies, by the shape of the corolla and the 

 many-flowered umbels. Though the flowers are comparatively
