leaflets rather convex, and by no means veiny; leaf-stalks 

 covered with glands, among which a few little hooked prickles 

 are intermixed. The flower-stalk is glandular, tube of the 

 calyx campanulate, and nearly smooth, sepals reflexed, quite 

 simple, villous, and glandular at the edge. The flowers are 

 very large, solitary, pale sulphur colour, quite double, very 

 fragrant, not expanding much more than R. sulphur -ea; but 

 under the influence of much heat, opening fully, when they 

 measure four inches across. This is one of the finest varieties 

 of China Roses known in the gardens, and so entirely dif- 

 ferent from any other, that it may be considered an important 

 addition to our collections. It appears to be hardy, but 

 thrives in a conservatory, where it expands its flowers better 

 than in the open air. 



XXXVI. Rosa gemella. Willdenow. 

 A plant of a Rose from North America was purchased by 

 Mr. Sabine some years since from Mr. John Frazer, under 

 the name of Rosa setigera, of Miciiaux; and subsequently 

 presented by him to the Society. It is a low bush, closely 

 covered with dull-green, scarcely shining leaves, which are 

 quite smooth above, and are hairy on the midribs beneath, and 

 on the leaf-stalks. The stem bears under each leaf two slender 

 falcate prickles, and on the stronger root-shoots at the base, 

 are several weak, straight, unequal prickles ; the stipules are 

 convolute, as in Rosa Carolina; the flowers bright red, 

 surrounded by longer leaves ; the flower-stalks are smooth ; 

 tube of the calyx short, ovate, and with the quite simple 

 sepals, glandular. This is plainly different from the obscure 

 species under the name of which it was sold, but I have no
