Cenothera Lamarckiana, Ser

This species is a casual which occurs in waste places, and is well known from the interesting experiments made by De Vries upon the variations to which the plant is liable, which he calls mutations. It differs from Cen. biennis (Sect. XII, Vol. V) in having more pointed radical leaves. The style is longer than the stamens. The capsule is less hairy. The plant is 2-4 ft. high, flowering between July and September, and is a herbaceous biennial.
