1064 Excluded Species 



374. Rosa acicularis Lindl. Prickly Rose. This species has been re- 

 ported from Lake County by Cowles, Hill, and Pepoon and from Porter 

 County by Nieuwland for Cowles. Mrs. Erlanson writes me that this 

 species does not occur in Indiana and that all reports should be referred to 

 other species or more probably to some natural hybrid. 



375. Rosa canina L. Dogbrier. I have found this species as an escape 

 in Harrison, Lagrange, and St. Joseph Counties. Also reported from St. 

 Joseph County by Nieuwland. 



Nat. of Eurasia. 



376. Rosa gallica L. French Rose. I have found this rose as an 

 escape in La Porte and Tipton Counties. 



Nat, of Eu. ; N. E. to Ind. 



377. Rosa multiflora Thunb. Japanese Rose. In 1933 I found a 

 specimen of this species far removed from a dwelling on the wooded border 

 of a small stream about 4 miles southwest of Canaan, Jefferson County. 



Nat. of Japan and China; Md., Ala., and Costa Rica. 



378. Rosa pimpinellifolia L. In 1932 I found a colony of this species 

 along the Monon Railroad about one and an eighth miles south of Ladoga 

 in Montgomery County. It seems to be spontaneous here. 



Nat. of Eurasia; sparingly naturalized, N. H. to Ont. and 111. 



379. Prunus angustifolia var. Watsoni (Sarg.) Waugh. I now refer 

 to the species the specimens formerly called this variety. See Deam's 

 "Shrubs of Indiana," ed. 2. 



380. Prunus Cerasus L. Sour Cherry. This species is no doubt 

 sometimes spontaneous in Indiana but there are only two or three reports 

 which I do not believe are sufficient to regard it as established. 



Nat. of Eu. 



381. Prunus cuneata Raf. In the Proc. Indiana Acad. Sci. 1920:227. 

 1921 I referred the broadleaf forms of my Prunus pumila to this species. 

 I now regard these specimens as broadleaf forms of Primus pumila. 

 Fernald regards this species as a synonym of Prunus susquehanae Willd. 

 (Rhodora 25:73. 1923). 



382. Prunus Persica (L.) Stokes. (Amygdalus persica L. of Britton 

 and Brown, Illus. Flora, ed. 2.) Peach. Reported as spontaneous from 

 three counties. Since there are annually thousands of peach seed cast 

 aside along roadsides, fences and in fields, waste places, and woodland, the 

 surprising thing is that this species is not common or at least frequent. It 

 is, no doubt, more common than reports indicate but I do not believe it 

 should be included in our flora. 



Nat. of Asia. 



383. Prunus susquehanae Willd. Reported from the dunes area by 

 Peattie. Fernald (Rhodora 25:74. 1923) cites Hill's specimen no. 117 

 from a dune near Indiana Harbor as belonging to this species. I believe
