Excluded Species 1065 



all of the sand cherries of Indiana belong to the same species and I have 

 placed them under the name of Primus pumila. Peattie, in his key, says 

 the fruit of Prunus pumila is "purple or black" and that of Prunus sus- 

 quehanae is "claret red." I have noted the difference in color in that the 

 fruit of all the plants are claret red at first and at maturity are black or 

 purplish, turning from a red to black just as do species of Aronia, Amelan- 

 chier, and Rhamnus. To find one plant with black fruit and one with claret 

 red fruit is not evidence of two species unless supported by other dif- 

 ferences. 



384. Cassia Tora L. This species has been reported from Clark, Floyd, 

 and Jefferson Counties. It does not appear in a list of plants collected by 

 Dr. Clapp in the vicinity of New Albany. Although Indiana is included in 

 its range in Gray's Manual, there is no specimen in the Gray Herbarium. 

 Since I have not been able to find a specimen it is excluded. 



Pa. to Ind. and Mo., southw. to Fla. and Tex. ; also from Mex. to Bolivia 

 and in the tropics of the Old World. 



385. Baptisia alba (L.) R. Br. Reported from Floyd County on the 

 authority of Clapp. Before the publication of Gray's Manual in 1840 this 

 species was not separated from Baptisia leucantha. Clapp, in his Medicinal 

 Plants of the U. S., published in 1852, had dropped this species and re- 

 ported Baptisia leucantha. 



Atlantic Coastal Plain from N. C. to Fla. 



386. Medicago hispida Gaertn. This species was reported without data 

 from Monroe County by Andrews. Since no specimen was preserved and 

 there is no evidence that it is established, it is excluded. 



Nat. of Eurasia ; sparingly found in the Atlantic Coast and Pacific Coast 

 States and rarely found in the interior; more common in the Gulf States 

 and southw. 



387. Medicago hybrida (Pourr.) Traut. This species was reported 

 by Hansen (Proc. Indiana Acad. Sci. 1923: 216. 1924) as found along 

 fence rows on the Purdue University Agricultural Experiment Station 

 farm. Search for it in 1934 showed that it had entirely disappeared. 



Nat. of Eu. 



388. Trifolium incarnatum L. Crimson Clover. There are only two 

 reports of this species and it is doubtful whether either specimen was an 

 escape. At least there is no evidence that it has become established. 



Nat. of Eu. ; naturalized along the Atlantic coast from Maine to Va. 



389. Trifolium reflexum L. This species was reported by Blatchley, 

 Coulter, and Schneck. I have the Blatchley specimen and it should be 

 referred to the variety. It is doubtful whether the species occurs in 

 Indiana and I believe all of our reports belong to the variety. Since our 

 manuals do not separate the glabrous form from the pubescent one, the 

 range of the species in them includes the range of the variety. I have seen 

 specimens from North Carolina, Missouri, Florida, Georgia, and Texas.
