ERIOGONUM VISHERI 

 DAKOTA BUCKWHEAT 



Dakota Buckwheat is an annual with slender taproot and single stem much branched, 15-25 cm tall. Leaves are glabrous, 

 in a basal rosete, the blades ovate to reniform, 15-20 mm long. Bracts of the infloresence are elliptic, involucres are 

 on slender peduncles or sessile in an erect or spreading infloresence. Flowers are 1-few per involucre, yellow. 



Readily distinguished from the two other annual species of ERIOGONUM in Montana; E. ANNUUM has cauline leaves 



rather a distinct basal rosette and E. CERNUUM has strongly reflexed involucral peduncles rather than an erect to 



spreading infloresence. ^
