Old sandy fields near Oneida lake. Introduced from Europe. June - July. Intermixed 

 with this plant there are two hybrid varieties, one of which has the stalks simple or slightly 

 branched at the top, with yellow flowers, and leaves resembling those of V. Thapsus ; the 

 other has the tops much branched, whitish flowers, and leaves more like those of V. Lychnitis. 

 These were first noticed by Dr. Knieskern.
