ROSE FAMILY. Rosacese. 



A low slender-stemmed species with 



Rosa humilis 



Pasture Rose straight> slight t } 1O rns, and narrow, 



spreading stipules. Flowers often solitary. 

 1-3 feet high. Under the name Rosa humilis lucida 

 (Rosa lucida of Gray's Manual, sixth ed.), the rose of 

 New Jersey, Pennsylvania, and the west is described by 

 Britton and Brown as having thick shining leaves with 

 broad stipules, and numerous flowers. Under Rosa 

 humilis, the description embraces a narrow, toothless 

 stipule, usually five leaflets, thin and somewhat shining, 

 few or solitary flowers, a glandular-hairy calyx and 

 stem, and sepals commonly lobed. Me. to Minn, and 

 south. 



Northeastern Tllis is a wild rose f the n r theast, 



R^SC limited to that section lying between Mas- 



Eosa nitida sachusetts and Newfoundland. It is char- 

 Pink acterized by a stem thickly crowded with 



bristly prickles, and spines scarcely stouter. 

 The 5-9 leaflets are ovate pointed, shining green, and 

 sharply toothed ; the stipules are broad. Flowers pale 

 pink, solitary, or very few in a cluster ; the fruit is globu- 

 lar, and the sepals are not lobed. A low species rarely 

 over 20 inches high. On the borders of swamps. 

 Sweetbrier ^ ne WU( ^ rose or eglantine of the poets, 



Rosarubiginosa adventive from Europe. It is remarkable 

 Pink for its sweet-scented foliage which is rem- 



June-July miscent of the fragrance of green apples, 

 and for its long, arching stems, which are beautiful 

 with compactly set clusters of pure pink bloom. The 

 very small 5-7 leaflets are double-toothed, roundish, deep 

 green above, and lighter colored beneath, where they 

 are resinous, and aromatic when crushed ; the leaves are 

 also characteristically glandular-hairy. The somewhat 

 small flowers are pink, or pale creamy pink, and clus- 

 tered along the main stem upon short stalks. The de- 

 cidedly recurved spines and the stem are madder brown 

 when old. 4-6 feet high. Common everywhere from 

 Tenn. and Va., northward. Another foreign species, 

 Rosa canina, but slightly separated from Rosa rubigi- 

 nosa, has usually simply toothed leaves which are not 

 so odorous. Common in the valley of the Delaware.
