MR. BENTHAM ON LOGANIACEiE. 



57 



The nearest approach to Spermacocece among free Monopetalce 

 must be sought for among Verhenacecs, although I am not aware 

 of any of them having a sufficiently marked tendency to stipular 

 appendages and regular flowers to be referred to Loganiacece, and 

 I know of no genera whatever with free ovaries representing either 

 Naucleece or Stellatce. 



The following table will best show the double arrangement of the 

 known genera of Loganiacece according to the nature of the fruit, 

 or according to the aestivation of the corolla : — 



I shall now proceed to enter into some details with regard to 

 each of these tribes and genera. 



Tribe I. ANTOISTnLE. 



Of the Antoniece, or Cincfionece with a free ovary, we have four 

 genera. Three of them, the South American Antonia, the African 

 listeria, and the Asiatic Norrisia, each with a single species, agree 

 with some of the smaller-flowered Cinchonas in inflorescence, in 

 the valvate aestivation of the corolla and general habit ; the fourth, 

 Gelsemium, North American and Asiatic, corresponds with Ma- 

 nettia in its climbing habit, inflorescence, and imbricated (quin- 

 cuncial) aestivation of the corolla. In all, the stipules are much 

 less developed than in the corresponding Rubiaceous genera, 

 being almost reduced to an elevated line connecting the stipules, 

 and thus showing some approach to Apocynece.
