This species approaches so near to O. fruticosa that it is 
difficult to define the distinction, though their other ha^ 
bits are so very different. The present species flowers a 
short time, the stems decay, and form immediately a 
tuft of large radical leaves. O. fruticosa flowers till 
late in autumn, and nevershows its radical leaves in that 
manner. The differentia specifica of O. fruticosa will 
be O. fruticosa, tenue pubescens ; caule a basi ramosa, 
divaricata, foliis sessilibus lanceolatis subdentatis acutis, 
capsulis pedicellatis oblongo-clavatis angulatis. 
Oenothera macrocarpa. — O. glabriuscula j caule ramoso, 
foliis lanceolatis, petiolatis, distanter glanduloso-denti- 
culatis margine nervisque sericeo-albidis, petalis cum 
acumine obcordatis, capsulis ellipticis 4-alatis brevis- 
sime pedicellatis. 
O. missourensis. Bot. mag. 1 5Q2. 
On the banks of the Mississippi, near St. Louis. 
July — Oct. V. V. in Hort. Lambert. This species ex- 
ceeds in size and beauty of its flowers any other one 
known j they are of a bright yellow, very large, and 
open about five o’clock in the evening. The calyx is 
covered with a very fine and white silky down, and is 
spotted with purple. The figure in the Botanical Ma- 
gazine is apparently taken from a very weak and starved 
plant : the flowers of those in possession of A. B. Lam- 
bert, Esq., were nearly six inches in diameter, and the 
tube nearly seven inches long. There is an inequality 
on the edges of the petals, but by no means can it be 
called serrulate, which term has been introduced in the 
differentia specifica, and strongly but erroneously ex- 
pressed in the figure. The specific name given there 
\s inapplicable, as it never was found any where else.
