ABALON Adanson. Veratrun L. Heloni' 

 as Alton and all our Botanists. Melanthimn 

 Walter, Diclinotrys Raf. meaning two beds 

 racemes. 



Dioical. Corolla Cpetals linear, Stamens 6 

 filiform longer, anthers bilobed adnate. Pistil- 

 late flowers with 6 rudiments of stamens, pis J 

 til Sgrooved, 3stigmas sessile reflexed. Cap- 

 sule ovate Sgrooved 3celled, cells with many 

 seeds angled acute. Habit, Caulescent, leaves 

 scattered, flowers in long racemes. 



Adanson good name meaning not in a ball, 

 was applied to the Helonias of L. as this Ge- 

 nus must certainly be divided, this good old 

 name ought to prevail, unless mine of Diclino- 

 trys is prefered. Linneus made many blunders 

 on this plant, uniting to Veratrum and calling 

 it V. luteum altho' the flowers are white. We 

 know only one Sp. as yet ; but it has many vari- 

 eties or deviations. The divided stems are 

 found so far apart, that no fecundation can take 

 place. The sterile plants are more common 

 than the others. This pistilate become fertile 

 at a great distance from them.
