Shrubby (Enothera, or Tree-primrose, Sun-drops, 



A very handsome species, with much darker yellow flowers 

 than those of No. 1. From two to three feet high. The flow- 

 ers of this species, likewise, open at evening-, and become par- 

 tially closed when the sun appears. In shady damp woods, and 

 on the borders of rivulets, ditches and other waters ; common. 

 Perennial. July.

 ceolate, or ovate-lanceolate, acute, subdenticu- 

 late, petals obcordate, longer than broad ; points 

 of the calix very short 5 capsule subsessile, al- 

 ways smooth, oblong, and 4-winged; raceme 

 naked below. — Nutt, 



Generally confounded with No. 2, but very distinct. The 

 stem is simple and slender, and the flowers much smaller than 

 in that species. Grows in dry fields exposed to the sun, and on 

 high exposed banks bordering Cooper's creek, Jersey. On the 

 Woodlands, not unfrequent. Perennial. August.

Scollop-leaved (Enothera, 



A semi-procumbent species, not as handsome as the gene- 

 rality of Oenotheras. It varies very much in size; often being 

 in flower when only an inch and a half high. In this state the 

 leaves are entire, or nearly so ; and has been mistaken by 

 Pursh for a different species. It is his 02. minima. Generally 

 a foot high, but sometimes more. In sandy fields of Jersey, 

 every where very abundant. Annual. June, July.
