Tessarandra. 



With the exception of a single instance, recorded by Aublet, 

 all the plants belonging to the family of the Oleaceee, including 

 the FraxinecE, possess unsymmetrical flowers, i. e. a small 4-par- 

 tite calyx, a corolla cleft to the base into four divisions, and only 

 two stamens : it will not therefore excite surprise, if we find a 

 plant offering the normal number of stamens. This indeed 

 occurs in the case of a very pretty shrub that I found near Rio
