MUHLENBERGIA 



STUDIES IN TRIFOLIUM II. 

 By P. Rkveridge Kennedy 



The second group in the Amoria section may be called the 

 stoloniferum group, with the following representatives: 



Stoloniferum group 

 T. stoloniferum T. virginicum 



T. reflexum T. amphianthum 



T. reflexum glabrum 



T. stoloniferum Muhl. Cat. 70. 1813. 



The original description of this well-known species is quite 

 meagre, being as follows: 



Corolla alb. Perennial, f running buffaloe 



\ clover. 



Ohio, Kent. Pens. H. fl. Jun. 

 The first description from which one could really identify 

 the plant is in Torrey and Gray's Flora 1: 315, although one 

 can get some idea from Eaton's Manual, Ed. 7, 564. 1836. In 

 specimens in the herbaria that I have examined, this species has 

 quite frequently been mistaken for reflexum, hybridum, caro- 

 linianum and repem. When the stolons are not well developed 

 it resembles very closely T. reflexum glabrum. It seems to be 

 more limited in its distribution than T. reflexum and its variety 

 glabrum. The following account of this species, with a figure, 

 is found in Bull. U. S. Dept. Agric. Div. Agrost. 2: 49: 



A low, smooth perennial, which sends out long runners from 



<x the base of the stem. The flowers are white, tinged with pur- 



1 pie, in loose heads. The leaflets are broadly obovate and mi- 



- nutelv toothed. A native species, growing in open woodlands
