locality where it was first discovered by Bartram about 1773, although 

 as I have shown elsewhere (Gates 1911 a), it originally extended east- 

 ward to Virginia and Carolina, and the first introduction of it, or a 

 ■closely related form, into Europe must have occurred from the latter 

 region at least as early as 17 14, (Barrelier's Plantae per Galliam, 

 Hisp. et Ital. observatae). 



Fig. I. Seedlings of 0. grandiflora. 



From these Alabama seeds I grew in 1910 a culture of fifty-five 

 plants which proved to be very uniform. A detailed description of 

 the characters of the species has been given by Miss Vail (1907), and 

 I have pointed out its many features of contrast with the Laniarckiana 

 series of forms (Gates 1909).
