* Lpavenwmihia stylosa Gray. Habitus the same like the former, but 

 a little more slender. It is also either stemless or caulescent, not strictly 

 stemless, like Dr. Gray thought it to be from stemless specimens sent to 

 him. Robust, plants have the ascending stems terminating with a 

 fasciculate inflorescence. Silicle broadly oval or oblong and 2 lines wide 

 and 5-12 lines long, plane, surmounted by a slender style 3-4^ lines long : 

 Seeds 8-6 orbicular, distinctly Avinged; embryo as in the preceding; 

 petals during anthesis pure golden yellow throughout, marcescent and 

 ehrivolling they turn to a purplish-white. 



First collected in the cedar barrens at Lavergne, one mile southeast 

 from the station, June 2, 1879, in a springy spot associated with Isoetes 

 Buttleri and Schconolirium Carolinianum. Also found in a similar spot 

 near Green Hill, Wilson Co. 



Leavenivorthia Michauxii Torr. occurs in the same locality close by, is 

 always much smaller ; stigma sessile or subsessile. Ttie name Cardamine 

 unifiora may have originated in an oversight of robuster specimens or 

 a too early collection. Vide Bot. Gaz., March, 1880.
