I have never seen this plant in flower, aod the losa of my specimens, 

 prevents me from speaking of it with certainty, and perhaps rcmovinff 

 .some obscuritj that hangs over the soutliern species of this genu^ 

 The A. integrifolia of Walter is unknown to me, unless the Sroyrnjfc 

 um mtegerrimum was the plant he described. 



_ Grows in rich soils, in the upper country, descending as low as St« 

 Johns. The roots are a favorite food of hogs, who sometimes ai> 

 ^,uire b}' this diet a fragrance which is not their common portion.

If this be the Sison marginatum of Mi chaus, as Dr. Muhlenberg 

 suspected (aad the plant agrees minutely with his description), it 

 grows « in the swamps of Carolina." Mich. I have not seen it is 



vama.
