The dog rosebush, Rosa canina, Linn., is a very common shrub in hedges around 

 Paris. Its stems are straight, slender, and smooth. The branches are equipped with reddish 

 hooked thorns that are wide at the base. The leaves consist of three, five, or seven oval 

 serrate leaflets. The flowers are slightly pink. Three sections of the calyx are pinnatifid; 

 two are entire. The fruit is oval and smooth. 



The sweet briar, Rosa rubiginosa, Linn., grows to a height of three or four feet on 

 branchy stems that bristle with slightly hooked thorns. The leaves consist of five or seven 

 dentate oval leaflets. The undersides and margins of the leaves are covered with a reddish 

 glandular down that unquestionably imparts a strong scent of reinette apple when they're 

 bruised. The small flowers are light pink with indented petals. The fruit is an ovoid berry, 

 most often with a glandular nap. 



The cinnamon rosebush, Rosa cinnatnomea, Linn., is a shrub growing four or five 

 feet high on a stem with smooth cinnamon-colored bark and with hooked thorns that are 

 set two or three together at the bases of the leaves and the branches. The leaves consist of 

 five or seven oval leaflets finely denticulated on the margins. They have stipules that are 

 wide, entire, and almost as large as the pedicels. The flowers are red and fragrant. The 

 calyx has five entire sections that are slightly cottony on the margins. 



The Scotch rosebush, Rosa spinosissima, Linn., [Translator's note: also 

 designated R. pimpinellifolia (p. 0495 above)] is a bushy shrub about three feet tall. The 

 stems are brown and are covered with thorns that are sharp and almost straight. The 

 leaves consist of five, seven, or nine small, oval, smooth dentate leaflets. The flowers are 

 white,
