In U|per Louisiana. Bradbury. $. v. $. in Herb. 

 Bradbury. Not above four inches high ; flowers large, 

 white. This species is intermediate between 0. telra- 

 plera and O. sinuata.

 In South Carolina. Fraser. 1/. June^ July. v. v. in Hortis. 

 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 speclfica of O.fruticosa will 

 be O. fruticosa, tenue pubescens ; caule a basi ramosa, 

 divaricata, foliis sessilibus lanceolatis subdentatisacutis, 

 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. ]5Q2. 



On the banks of the Mississippi, near St, Louis. i$ . 

 July — Oct. V. V. in Hort. Lambert. This species ex- 

 ceeds in size and beauty of its flowers any other one 

 known ; 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 

 is inapplicable, as it never was found any where elscj,
