 ellipticis quadrialatis pedicellatis. 



The flowers of the Miflburi Evening Primrore are large and 

 fhewy. In the denticulation of the leaves, and the length of 

 the tube of the calyx, it refembles longifiora, but is a much 

 fmoother plant, and differs materially "in the fruit, which is 

 frnooth, oval, four-winged, and ftands on a footftalk inftead of 

 being feflile, cylindrical, and hifpid. The root is faid to be 

 perennial. 



Found by Mr. Nuttall in the neighbourhood of the 

 Miflburi in North- America, who brought many novel and curious 

 plants from that country; fome of which that flowered at 

 Liverpool laft year, he kindly tranfmitted us recent fpecimens 

 of. But our draughtfman being unfortunately ablent on a 

 journey into Wales at the time, we had no opportunity of 

 availing ourfelves of them for this work. 



We do not find that this fpecies has been before noticed : it 

 feems to differ from every one defcribed by Miciuux or by 

 Pursh, whofe valuable Flora, fpeedily to be published, we 

 have been favoured with the opportunity of confulting. Flowers 

 in June and luly. Communicated from the Sloane-Square 

 Nurfery by Meffrs. J. and J. T. Fraser.
