ROSACE AE. — ROSA 311 



(Veitch Exped. No. 945); without locality, A. Henry (No. 5973). 

 Eastern Szech'uan: Wushan Hsien, woodlands, alt. 1000-1.500 

 m., December 1907 (No. 666); same locality, A. Henry (No. 7100). 



This species is well distinguished from all its allies bj' its large ovoid to obovoid 

 ellipsoid fruit, in No. 666 sometimes even exceeding 1.5 cm. in length. It is 

 perhaps most closely allied to R. Brunonii Lindley, which has a paniculate corjTnb 

 and smaller globose fruit. R. Gentiliana L(5veill6 & Vaniot differs in its glabrous, 

 5-foliolate leaves, which are glaucescent below and have larger more coarsely 

 toothed leaflets, and in its gray stems and globose fruit. 



Rosa Helenae is very abundant in rockj- places from river-level to 1500 m. 

 everywhere in western Hupeh and eastern Szech'uan, but has not yet been re- 

 ported from farther west. It forms in wayside thickets and by the banks of streams 

 tangled masses often 6 m. tall and as much through, and in the margins of woods 

 it rambles over small trees. When covered with masses of its white fragrant 

 flowers this Rose is very beautiful. It has proved quite hardy and flowered pro- 

 fusely at the Arnold Arboretum. Under the original Seed No. 431 seeds of R. 

 Helenae and of R. Rubus have been distributed; the plant cultivated at Kew 

 under No. 431 belongs to R. Rubus according to specimens received from there. 



This new species is named for my Wife. (E. H. W.)
