maturity. This species, formerly more extensively cultivated 

 than now, has given rise to few varieties, which are for the 

 greater part forgotten. 



R. rapa, the Turnip Kose a bush about 4 or 5 feet high, 

 and almost entirely destitute of spines comes from North 

 America. Leaves of 5 to 9 oblong shining leaflets, assuming a 

 reddish tinge in Autumn. Flowers in clusters, of a bright red, 

 sometimes white, often double even in the wild state. This 

 beautiful Eose, rather rare in France, is frequently cultivated 

 in England, where it is advantageously employed in masses in 

 landscape gardens. The name Turnip Eose probably originated 

 from the resemblance of the spherical fruit surmounted by the 

 leafy calyx-lobes to a turnip. 



R. Caroliniana, the Carolina Eose, is also a native of North 

 America, inhabiting marshy ground. A shrub 5 to 10 feet higL, 

 remarkable for the length of its stipules and the form of its 

 leaflets, which are oval, acute, dentate, of a deep green above. 

 Flowers in clusters, large, rosy carmine. This, like the fore- 

 going, is common in English collections, and is equally effective 

 in clumps. 



IV. Eos^; PIMPINELLIFOLI^E, or Burnet Eoses. Shrubs with 

 or without spines, whose fruits retain the convergent calyx-leaves 

 until maturity. This tribe is more easily distinguished from 

 the others by the number of the leaflets (from 7 to 15) than by 

 all the other characters. The varieties called Scotch Eoses of 

 our gardens belong to this tribe. The species most worthy of 

 notice are : 



R. pimpinellifolia, syn. R. spinosissima, the Burnet or 

 Scotch Eose, so named from its small rounded leaflets, recalling 

 those of the common Burnet. It is a native shrub, usually 

 forming dense bushes 2 to 3 feet high, with about 7 orbicular 

 dentate leaflets to each leaf. The flowers are small and solitary, 

 quite white or shading off to yellow around the centre. This 

 charming little Eose has produced several double varieties, 

 amongst which we may mention the Double White, Double 

 Yellow, Estelle, with rose-coloured flowers, and Stamuells, with 

 delicate rose-coloured flowers, said to be perpetual flowering. 



There is a very small-flowered form in the South of 

 France, considered a distinct species by De Candolle and 

 Lindley, under the name of R. myriacdntha, besides many 

 other forms found in this country, which have received spe- 

 cific names.
