Habitus. Herba erectae. Folia opposita, nunc 

 alterna ! vel verticillata. Umbellcz interpetio- 

 lares. 



Patria. America Septentrionalis. 



Obs. The species of this genus which I have 

 examined, are A. Syriaca, (most improperly so 

 called, as it is a native of North America only), 

 amcena, purpurescans, variegata, curassavica, 

 nivea, elevata, parviflora, incarnata, decumbens, 

 verticillata, tuberosa, of Willdenow's Spec. 

 Plant., and some unpublished species in the 

 Banksian Herbarium ; and there can be little 

 doubt that A. pulcbra, citrifolia, Mexicana, 

 linaria, rubra, and all the species of Michaux, 

 belong to it.
