12 JOURNAL OF THE ARNOLD ARBORETUM [vol. hi 



This hybrid was raised by G. Paul & Sons of Cheshunt, England, and 

 first distributed in 1903. It is a very vigorous shrub with large and 

 showy white flowers; its long prostrate stems form in course of time an 

 impenetrable bush to 6 feet high and of great width. The parentage of 

 this Rose is usually given as R. rugosa Thunb. and R. Wichurauana 

 Crdpin, and without doubt it is a hybrid of R. rugosa with a trailing spe- 

 cies of the Synstylae group, but in the texture of the leaves and their 

 size and serrature and in the slight serration of the stipules it shows much 

 more affinity to R. arvensis Huds. (R. repens Scop.) than to R. Wichurai- 

 ana; there is no trace of the small coriaceous lustrous leaves and the 

 conspicuously dentate stipules in this hybrid. I, therefore, am inclined 

 to consider the Rose known as R. rugosa repens alba a hybrid between 

 R. rugosa and R. arvensis and it may bear the name of its raiser, George 

 Paul, a name which figures so prominently in the history of the develop- 

 ment of garden Roses. 



The form w r ith rose-colored flowers of apparently the same parentage 

 may be known as R. Paulii f . rosea, comb. nov. (R. rugosa repens rosea 

 Darlington in Rose Annual, 1915, 43). 



The similar R. Jacksonii Willmott (R. rugosa x Wichuraiana) may be 

 distinguished by its 7-9 smaller leaflets, lustrous above, less coarsely and 

 almost crenate-serrate, and by the more densely and more deeply glandu- 

 lar-denticulate stipules. 



X Rosa Bruantii nom. nov. (R. odorata [vel R. dilecta] x rugosa.) 

 Upright shrub to 2 m.; branchlets glabrous, often slightly bloomy, 



armed with numerous straight prickles to 8 mm. long, passing into bristles. 

 Leaves 5-7-foliolate; leaflets generally elliptic, 3-5 cm. long and 1.5-3 

 cm. broad, the terminal one often broadly obovate or ovate and to 3.5 

 cm. broad, acute or short-acuminate, broadly cuneate or sometimes, 

 particularly the terminal leaflet, nearly rounded at base, rather closely 

 and usually more or less doubly serrate, bright green, glabrous and nearly 

 smooth above, grayish green and pubescent on the veins and veinlets 

 beneath; petioles and rachis villose and armed with few straight or nearly 

 straight unequal prickles; stipules rather narrow, doubly glandular- 

 denticulate, ciliolate, with lanceolate or ovate-lanceolate upright or slightly 

 spreading auricles. Flowers in usually 2-4-flowered corymbs, in the 

 type white, fragrant, nearly double and 7-8 cm. across; pedicels slender, 

 3-5 cm. long, stipitate-glandular and bristly; ovary subglobose, glabrous; 

 sepals ovate oblong, caudate, entire or sparingly serrulate at the elongated 

 apex, sparingly stipitate glandular on the back, and finely villose toward 

 the margin. 



For the type of this hybrid group which is intermediate between R. 

 rugosa Thunb. and the Tea Roses or Hybrid Tea Roses, I take "Madame 

 Georges Bruant," raised by Bruant and offered to the trade in 1887, and
