said to be a hybrid between R. rugosa and the Tea Rose "Sombreuil." 

 The description given above is based on specimens collected June 20, 

 1921, and preserved in the herbarium of the Arnold Arboretum. Another 

 Rose stated to be of the same origin is "Blanc Double de Coubert" (Co- 

 chet-Cochet, 1892). It will be in many cases difficult to draw a line 

 between this group and R. Arnoldiana comprising the hybrids of R. ru- 

 gosa and the Hybrid Perpetuals, as the Hybrid Perpetuals and the Hybrid 

 Tea Roses are closely connected by intermediate forms, but it does not 

 seem advisable to merge these two groups under one name. Another 

 related group constitute the hybrids between R. rugosa and R. chinensis, 

 the type of which is R. calocarpa Willmott, a single-flowered and freely 

 fruiting plant.

This hybrid which was raised by I. C. Schmidt of Erfurt, sometime 

 before 1896 from seed of R. laevigata Michx. resembles in its general 

 characters its parent and was considered by Mottet only a variety of R. 

 laevigata, but its larger pink flowers, the occasional occurrence of 5-folio- 

 late leaves, the less bristly receptacle, the exserted styles and particularly 

 the stipules adnate about one half of their length to the petiole show the 

 influence of some other Rose which was to all appearances a Tea or a 

 Hybrid Tea Rose; the somewhat exserted styles, the shape of the stipules 

 and the texture, shape and serration of leaflets indicate the influence of 

 R. odorata Sweet.

The forms of this group, the type of which may be considered "La 

 France," are intermediate in their characters between the Tea Rose, R. 

 odorata Sweet and the Hybrid Perpetuals which belong to R. borboniana 

 Desp. They are slender-branched, sometimes sarmentose shrubs; the 

 stems armed with scattered straight or slightly hooked prickles. The 

 leaves are glabrous and of firm texture, often purplish when unfolding. 

 The flowers are usually solitary or in few-flowered corymbs, white to 

 red, or sometimes yellow, fragrant and when opening are of a distinct 

 conical shape with recurving petals.
