Note on Oholaria virginica, L. By Asa Geat, M.D., F.M.L.S.

[Read April 15th, 1856.] 



Seveeal years ago, in a memoir* in which Oholaria virginica is 

 figured and described, I endeavoured to show that this genus 

 should be referred to the order Gentianece, notwithstanding a 

 peculiarity in its placentation. I wish now to say, that it should 

 be referred there on accoimt of its placentation. Had I properly 

 noted at the time what Grisebach states (in his Gen. et Sp. Gen- 

 tianearwm), respecting the ovules sometimes occupying several 

 series somewhat remote from the sutures, or had I been led to in- 

 spect the ovary of almost any of our common Gentians, the case 

 would have been clear at once. It is only recently that my former 

 pupil, Mr. Henry J. Clark, has called my attention to the fact, 

 hitherto unknown, I believe, that the ovules in most of our Gen- 

 tians of the United States occupy the whole, or nearly the whole 

 parietes of the ovary ; sometimes in nearly definite rows, as in 

 G. quinqueflora, but more commonly indefinitely crowded over
