Boiss.), but is readily distinguished by its more slender habit, the 

 linear leaf-blades, the oblong acute bracts which subtend the flow- 

 ers, and the ovate calyx-segments. 



Gentiana quinquefolia L. Sp. PI. 230. 1753. 



Mr, A. M. Huger has sent me specimens of this gentian from 

 the vicinity of Waynesville, North Carolina, noting; that the plants 

 often produce a prodigious number of flowers, he having counted 

 over three hundred and sixty on some specimens. He has also 

 observed the extensive altitudinal range of the species, recording 

 that it grows from the " bottoms" to "balds," in this case from 

 about 300 meters to nearly 1500 meters. I have noticed the same 

 occurrence in northern Georgia. 



Ipomoea barbigera Sweet, Brit. Fl. Gard. //. 86. 181 8. 



Dr. Mohr has lately pubhshed an interesting note on this 

 species in this journal ;* the plant has apparently not been col- 

 lected many times since its discovery and it would be desirable 

 to know more of its geographic range. Prof. Carl F. Baker has 

 sent me specimens collected near Auburn, Alabama, in the (all 

 of 1896. 



Ipomoea purpurea (L.) Roth, Bot. Abh. 27. 1787. 

 Prof. Baker has also sent me this morning glory, collected 

 near Auburn, Alabama, thus giving us a station between the At- 

 lantic States and Texas ; this break in its range is indicated in 

 the Synoptical Flora. f 



Mentha rotundifolia (L.) Huds. Fl. Angl. 221. 1762. 

 Only one station in the Southern States, namely, " near Wil- 

 mington, North Carolina,"! has been recorded for this mint. How- 

 ever the species is spreading; in 1891 Miss K. A. Taylor 

 collected specimens in a wet meadow near Columbia, South 

 Carolina, and in 1895 I found it abundant near Trader's Hill in 

 southeastern Georgia.
