NOTES ON CHINESE ROSES.

and, moreover, so well known, that no description is necessary. B. Biondii 

 and B. Giraldii, named by Crepin in honour of two Italian missionaries 

 in China and described provisionally by him in Bull. Soc. Bot. Ital. 1897, 

 232-3, are not yet in cultivation. B.Prattii (Hemsley in Journal of the 

 Linnean Society, xxix. t. 30) is a Western Chinese species yet to be 

 introduced and a remarkably distinct plant, much resembling some 

 Zanthoxylum in general aspect ; it is easily distinguished by its small 

 flowers, reflexed calyx-lobes, and small linear-lanceolate, closely-arranged, 

 obscurely- toothed leaflets. 



Group VII. — Spinosissimce. — Two species enter into this group, our 

 common native B. spinosissima (Fig. 145) and B. xanthina, the latter first 

 introduced into cultivation from Afghanistan by the late Dr. Aitchison. 



Group VIII. — Gallicce. — No representative of this section of the 

 genus occurs in the Chinese Empire. 



Group IX. — Canince, — The common Dog Eose of our hedgerows may 

 be taken as the type of this section of the genus. In China only B. indica 

 and B. gigantea come into this group. The last-named species was first 

 discovered in Burma by the late Sir H. Collett, but more recently has 

 been collected on the mountains of Yunnan, both by Dr. Henry and 

 by Hancock ; we suppose that the name B. Collettii, which obtains in 

 some gardens for this species, has been given to it by some one desiring 

 to perpetuate the name of General Collett. It is important, however, to 

 distinctly state here that there is a true B. Collettii which hails from the 

 Shan States, and is as distinct from B. gigantea as two Roses can be from 

 each other. B. Collettii (Crepin in Bull. Soc. Bot. Belg. 1889, 49) is a 

 small-growing small-flowered Rose near B. microcarpa, and is remarkable 

 for its free linear stipules, which are also fugacious. A good figure is 

 published in the Journal of the Linnean Society, xxviii. t. x. On the 

 other hand, true B. gigantea is a huge climber, with large leaves, and 

 flowers five inches in diameter. 



Group X. — Villosce. 



Group XI. — Bubiginosce. 



The first of these is represented in our gardens by the Apple Rose 

 (B. pomifera), B. mollis, &c. ; the second by the Sweet-brier, B. rubi- 

 ginosa ; the Chinese flora contains no representative of either group.
