Hypericum maculatum. Walt.

Hypericum perforatum. Lin. 

 Hypericum parviflorum. Lin. 

 Hab. Both common on the prairies near St. Louis — July. 



Hypericum rosmarinifolium. Ell. 



Obs. Stem, terete, somewhate angled, colored. Leaves 

 opposite, linear-lanceolate, shining, paler on the under sur- 

 face, obtuse, but terminated by a short mucronate point, 

 margin revolute and somewhat undulated. Flowers, nu- 

 merous, in a dichotomous terminal corymb. Styles three, 

 generally united.

 grounds near St. Louis. 



POLYANDRIA. POLYGYNIA. 



Porcelia triloba. Pursh. 

 Hab. Banks of the Illinois, and Mississippi, frequent— 

 April. 



Clematis virginiana. Lin. 

 Hab. High grounds near the mouth of the Missouri — 

 July. 



Clematis reticulata. Walt. 

 Hab. Banks of the Riv. des Peres, near St. Louis. My 

 specimens agree with the very accurate description of this 

 species, given by Dr. Elliott, in his sketch of the Botany of 

 South Carolina, and Georgia. Its coriaceous and distinctly 

 reticulated leaves sufficiently distinguish it from the allied 

 species.

Anemone virginiana. Lin. 

 Hab. Shady situations on the banks of the Merrimack, 

 and Missouri rivers — May.
