ROSACEAE 



Rubus 



13. Rubus laudatus Berger. (Rept. N. Y. Agric. Exp. Sta. 2: 79. 

 1925.) This species is fully discussed by Bailey in Gentes Herbarum 3: 

 265-269. 1934. Map 1140. Bailey cites two of my specimens, one from a 

 low, flat woods in Posey County 5 miles south of Caborn and one from 

 sandy soil on the Claypole Hill in Knox County. He gives the range as 

 from Missouri and Kansas to eastern Illinois. 



14. Rubus argutus Link. HlGHBUSH BLACKBERRY. Map 1141. This 

 species is frequent throughout the southern part of the state where it is 

 found in white clay soil in low ground and on high ground mostly with 

 beech and sugar maple. 



Va. to s. Ind., southw. to Ga. and Tenn. 



15. Rubus ostryifolius Rydb. (Britton. Man. Flora North. States and 

 Can. 497. 1901.) {Rubus Andrewsianus Blanchard.) Map 1142. Probably 

 only infrequent throughout the state, mostly in black and white oak woods. 



N. E. to Mich., southw. to N. C. and Kans. 



16. Rubus impar Bailey. (Gentes Herbarum 3: 269. 1934.) Map 1143. 

 This species so far is known only from the type locality which is an open, 

 level, post oak woods just southeast of Half Moon Pond about 10 miles 

 southwest of Mt. Vernon, Posey County. The soil of the area is a hard, 

 white clay and is infertile and sparsely wooded mostly with post oak and 

 an occasional black oak. The plants are slender and usually 3-5 feet high, 

 with a few short side branches and a slightly curved summit. 



17. Rubus frondosus Bigel. Map 1144. Probably found more or less 

 frequently throughout the state, growing mostly in dry soil. 



N. E. to Wis., southw. to D. C. and Mo. 



18. Rubus abactus Bailey. (Gentes Herbarum 2: 452-455. 1932.) 

 (Probably Rubus recurvans Blanchard.) Map 1145. Of our upright black- 

 berries this species is the most arching and widest spreading, often almost 

 as wide as long. Rather frequent in northern Indiana and in the "flats"
