LYCOPUS, L. 



In the last edition of the Manual of Botany, I was induced to con- 

 sider all the American Lycopi with acute-pointed calyx-teeth as forms 

 of L. Europceus. Having now bad occasion to study them anew, I 

 see grounds for a different opinion, and for disposing our species as 

 follows : — 



§1. Stoloniferce, — stolonibus filiforraibus elongatis apice demum 

 tuberiferis. 



* Calycis dentes 4, raro 5, cum bracteis brevissimis obtusi vel obtu- 

 siusculi, fructiferi nuculis breviores. 



1. L. Viuginicus, L. — Forma depauperata: L. xvni floras Michx. 

 Li. pumilus "Vahl. — Forma procera, var. macropiiyllus : L. macro- 

 phylhts, Benth. 



* * Calycis dentes 5, acutissimi, nuculis longiores. 



h~ Bracteas minima?: corolla calyce fere duplo longior : stamina 

 rudimentaria brevissima, ovalia seu linguajformia.
