Ihe nearest approach to Spermacocece among free Monopetalce 

 must be sought for among VerbenacecB^ 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 whateyei

Usterin 



American 



agree 



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

 the valvate {estivation of the corolla and general habit ; tlie fourth, 

 Gelsemimt, North American and Asiatic, corresponds with Ma- 

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

 cuucial) festivation of tlie corolla. , In aU, the stipules are much 

 less developed than in the corresponding Eubiaceous genera, 

 I'eing almost reduced to an elevated line connecting the stipules, 

 aud thus showing some approach to Apocynece.
