737. Robinson, B. L. The Eupatoriums of Bolivia. Contrib. Gray Herb. N. S., 61: 

 30-80. 1920. — The author gives a brief historical account of the progress of taxonomy in 

 Bolivia with particular reference to species of Eupatorium, of which 68 species are now known 

 to occur in Bolivia. Of these, 29 are known only from Bolivia. There is reason to suppose 

 that of the Eupatoriums indigenous to Bolivia a great part are still to be discovered. In the 

 present paper the species are grouped under the sections to which they are referred and 

 subsectional keys given to the species. Species previously undescribed in the present series 

 of papers are accompanied by a complete diagnosis. Specimens are cited for all species. The 

 following new varieties and forms and new combinations are included: Eupatorium tunari- 

 erse (E. conyzoides [Vahl] Ktze. var. tunariense Hieron.), E. patens D. Don var. typicum, 

 E. pyramidale Klatt var. angustifolium (E. amygdalinum Lam. var. revolutum [Pohl] Bak. 

 forma angustifolium Hieron.), E. rufescens Lund. var. typicum. — E. B. Payson.
