ROSA WOODSII Lindley 

 Woods's Rose 



This rose, fig. 29, is an erect shrub with terete, glabrous 

 stems li/^ to 6 feet high, which are armed with numerous 

 straight or slightly recurved prickles. The leaves are made 

 up of 5 to 7 obovate leaflets, which are wedge shaped at the 

 base, glabrous on both sides, and glaucous beneath. They are 

 14 to 1/^ inch long, or rarely longer, and serrate around the 

 upper part of the margin. The stipules are glabrous, usually 

 without glands, and entire or a little toothed on the margins. 

 The sepals are glabrous or slightly glandular on the back and, 

 after flowering, stand erectly together and are persistent on 

 the fruit. The flowering period is from May to July. The 

 glabrous, red fruit is globose, only slightly more than ]/8 inch 

 in diameter at maturity, and it ripens in the autumn. 



Distribution. — This rose is an inhabitant of river banks 

 and thickets from Manitoba to North Dakota and south to 

 Kansas and westward. As a plains species, it occurs rarely 

 in Illinois, being actually reported only in Jo Daviess County, 

 in the northwest corner of the state, and in Pope County, in 

 the extreme south.

 The Apple Family 



The apple family consists of shrubs or trees which bear simple 

 or pinnately compound, alternate, stipulate leaves and perfect, 

 regular flowers with a well-developed hypanthium adnate to the 

 ovary, which in maturity becomes fleshy and constitutes a part 

 of the fruit. The sepals and petals are for the most part 5 in 

 number; the stamens are distinct and numerous and inserted 

 on the margins of the receptacle ; and the ovary consists of 

 1 to 5 united pistils, the cells being 5 and the corresponding 

 styles distinct or sometimes partly united. The fruit is more 

 or less fleshy, apple-like, and generally is called a pome. 



The apple family, sometimes considered not distinct from the 

 rose family, consists of some 20 genera and more than 500 

 species, which are widely distributed in Europe, Asia and North 

 America and extend southward to Mexico and into South 

 America along the Andes. The family is noted for the useful-
