COLUMELLIE^l. I. COLUMELLIA. II. BOLIVAEIA. III. MENODORA. JASMINEACE.E. 



calyx and corolla of Menodbra, with those species of Jasmlnum 

 wherein the number of segments are indeterminate, will display 

 more clearly the intimate affinity existing between these two 

 families. It differs, however, essentially from Jasmineacece by 

 having an adherent ovarium, by the presence of a perigynous 

 disk, by the undivided stigma, and lastly by having an inferior 

 capsule with polyspermous cells. The imbricate aestivation of 

 the corolla, and adherent ovarium, with erect ovula, the presence 

 of a perigynous disk, and a capsule with polyspermous cells, 

 are characters sufficiently numerous and important to prevent 

 its ever being confounded with Oleince, and to establish it 

 as an osculant group between that family and Jasmineacece. It 

 appears also to be nearly related to Halesiacece, a small group 

 forming the connecting link between Oleince and Ebenacece ; 

 this group is principally distinguished from Columelliece by the 

 indefinite number of its stamina, and its simple stigma.
