 raised from seed received from Professor DeVries from the 

 Holland sand dunes resembled these American plants, but 

 were not absolutely identical.' 



" As compared with the (Enothera biennis, this is a lower 

 and more leafy bracted plant, with more numerous and 

 ascending leaves of narrower form and thicker texture and 

 less definitely denticulate. The lower with oblanceolate 

 tendency. The general pubescence is softer, denser and 

 more oppressed. The longer hairs tending to form a villous 

 or even pilose investiture, especially on the capsules. In 

 (Enothera biennis the sparcer pubescence is harsher and 

 more or less hirsute, the smaller hairs mostly erect and in- 

 curved. The seeds are considerably smaller, than these of 

 (Enothera muricata."
