EOSACEAE. — ROSA 313 



This species is well distinguished by its glabrous shoots which become pale gray 

 with age, by its glabrous 3-5-foliolate leaves which are shining green above, glau- 

 cescent and very pallid on the underside, with relatively broad, coarsely serrate 

 long acuminate leaflets occasionally abruptly rounded with a short acumen. The 

 flowers are very numerous in flattened or rounded corymbs; the fruit is small 

 and globose. 



Rosa Gentiliana is abundant in the mountainous region of western Hupeh and 

 eastern Szech'uan which would appear to mark its western limits of distribution. 

 It is partial to rocky places from river-level to 1400 m. altitude, forming tangled 

 masses 6 m. and more tall. The flowers are large, very fragrant, and their beauty 

 is increased by the golden-yellow anthers. L6veille describes the styles as "free" 

 in his Rosa adenoclada, but this is incorrect. Miss Willmott states that R. adenoclada 

 Lcveille is near R. lucidissima Leveille, but we consider the last named to be only 

 a state of the very different R. chinensis, f . spontanea Rehder & Wilson. It is prob- 

 able that Rosa moschata, var. densa M. de Vilmorin (in Jour. Hort. Soc. Lond. 

 XXVll. 482, fig. 134 [1902]) should be referred to R. Gentiliana Leveille, although 

 it is not stated whether the shoots and leaves are glabrous or pubescent. 



A picture of this plant will be found under No. 060 of the collection of Wilson's 

 photographs.
