MONADELPHIA. POLYANDRIA. 77 



Fl- Middle of June till September. Fa mat August, and after. 



Hah- Borders of woods; fields, &c. common. 6 to 13 inches high: flowers yellow. 



06.?. I have some small, erect specimens, with hirsute stems, and umbels longer than the leaves,— which 

 Mr. Schweinitz thought might be the O DiUcnii, of Pursh (O. furcatal Elliott) . Mr. Nuttall, however, 

 Beems to consider that species scarcely distinct from the O. strlcta. 



I have followed Michaux, in arranging thiagpnusin Monadelphia; to which place it appears to havequite 

 as much pretension, at least, as the genus Lobelia.

Obs. Spmosa is not a good name; as there are, in fact, no re al spines,— but mere minute points, or pro- 

 tuberances, ju.st below the axils, which can scarcely be considered as even the rudiments of spines. Is the 

 plant really spinosem its native regions.? It is a stranger here: and was somewhat rare when this catalogue 

 was commenced, in 1813— but it is now (1825) becoming quite common.
