__A very large genus of biennial herbs or suffrutices, common throughout North 
and South America, from which continents some species have become naturalized in 
Europe and Asia, and two have taken effectual footing in South Africa. Radical 
leaves mostly rosulate ; cauline alternate, entire or denticulate, sometimes sinuate or 
pinnatifid. wers axillary, solitary, or forming a terminal, leafy spike, very gene- 
rally opening in the evening ; whence the popular name of “ Evening Primrose” 
given to these plants. The generic name Ocnothera is derived from ouvos, wine, and 
Onpaw, to hunt ; the roots of CE. biennis were formerly eaten as incentives to wine-
