ROSACEAE 1 27 



The flowers stand solitarily at the end of the branches, or 

 in twos or threes, on pedicels about ^ inch long, which are 

 generally glandular-hispid but sometimes smooth. The calyx 

 tube is often glandular-hispid, and its lobes are lanceolate and 

 caudate, reflexed, and deciduous. The fruit, which matures in 

 autumn, is generally depressed, \^ inch wide or a little larger, 

 and bright red. 



Distribution. — This rose is a prairie species which ranges 

 from Indiana westward into ^Missouri and from Wisconsin and 

 Iowa south to Oklahoma. It grows throughout the prairie 

 region of Illinois and is to be looked for especially along road- 

 sides. The reddish foliage and the thicker leaflets serve as a 

 ready means of distinguishing it from the Pasture Rose. 



ROSA SUFFULTA Greene 



This rose, fig. 29, is a shrub with erect, generally simple 

 stems, which reach a height of 18 to 30 inches and are covered 

 more or less densely with straight prickles. The leaves are made 

 up commonly of 9, but sometimes of 7 or 11, obovate or broadly 

 oval leaflets, which are bluntly or acutely rounded at the apex 

 and narrowed at the base. Their margins are bluntly and 

 rather coarsely serrate, and the blades at maturity are generally 

 smooth above but pubescent beneath. Petioles and the rachises 

 are woolly pubescent and sometimes glandular-prickly. The 

 stipules are pubescent and dilated, and their margins are more 

 or less erose or dentate and studded with glands. 



The flowers stand in corymbs at the top of the stems and are 

 supported on smooth pedicels 14 ^o nearly l/^ inch long. The 

 calyx tube is glabrous, and its lobes are caudate, often expanded 

 at the tip, glandular on the back, and tomentose within and on 

 the outer margin. After flowering they are generally erect and 

 persistent. The red, globose or, rarely, pyriform fruit matures 

 in the autumn and is not quite 14 inch in diameter. The seeds 

 are attached to the bottom and near the base of the interior. 



Distribution. — This rose is a prairie species generally as- 

 sociated with typical prairie land. Its natural range is from 

 Alberta to Manitoba and south to Texas and New Mexico. 

 Illinois stands almost on the eastern border of its range, and 

 it is known to occur in northern, central and western, but not 

 the southeastern, sections of the state.
