size, I was able to observe only one ovulum, suspended 

 from a funiculus which was continued on one side into a 

 raphe ending at the lower and wider extremity of the 

 ovulum. These appearances leave the question of the ori- 

 ginal position of micropyle undetermined. 



Dr. Blume considers the capitate body as the true 

 stigma, and I have some reason to believe that this is also 

 the opinion of an excellent and more recent observer. I 

 have little doubt, however, that the emarginate or biden- 

 tate branch is the organ performing the function. In con- 

 nection with and in support of this opinion, I regard the 

 ovarium or pericarpium of Cardiopteris as composed of two 

 carpella, the line of junction being in the axis of the samara. 

 This I infer from the relative position of the supposed per- 

 fect and imperfect stigmata, the former presenting its 

 papillose surface to the latter, and both being in the plane 

 of the wings of the samara ; and these wings, as well as I 

 can judge, being anterior and posterior with relation to the 

 axis of the unilateral spike. 



With respect to the affinities of Cardioioteris, Dr. Wallich, 

 with whom the genus originated, and who first hazarded a 

 conjecture on the subject, was disposed to refer it to 

 SapindacecB ; Hasskarl (1. supra cit.) has placed it among 

 Euphorhiacece ; and Blume, who considers it as forming a 

 separate family {CardiopteridecB], has placed this family in 

 proximity with Verhenacece and Boragineee . None of these 

 approximations appear to me satisfactory, and although I 

 am aware of several important objections to the view, I am 

 inclined to consider Cardiopteris as an isolated genus or 

 family to be placed at no great distance from FhytocrenecB, 

 chiefly through lodes, under which genus I have given some 

 account of that family.
