STUDIES IN TRIFOLIUM— VI 

 By p. Beveridge Kennedy 



We have not intentionally taken up any species of Trifol- 

 itim for study that occur outside of the limits of the United 

 States, but some Mexican and South American species grrow in 

 the United States also, which has necessitated a general knowl- 

 edge of practically all the clovers on the American continent. 



Some collections from Bolivia, all named T. amabileYi. B. K. 

 attracted our attention as being different from those from Mex- 

 ico, the type country of that species. Unfortunately the sheets 

 bearing the type collection of the proposed new species have 

 nothing on them to indicate in what part of Bolivia the plants 

 were collected, but they bear the number 2819. Dr. Rusby in 

 working up Mr. Bang's Bolivian collections in the Bulletin of 

 the New York Botanical Garden 4: No. 14, lists this species on 

 page 343 as T. amabile^ but gives neither locality nor date of 

 collection. One of the sheets came to me through the herbar- 

 ium of Parke, Davis & Co., the other from the Missouri Botan- 

 ical Garden. The plants show characters which would indicate 

 that they had been growing under more favorable conditions of 

 moisture and soil than four more sheets which were collected in 

 the vicinity of La Paz. In these the stems are not so fistulous, 

 the leaves smaller, and the ve.xillum not so broad, besides other 

 characters that will be noted in the description.
