538. DETANDRA. 
This genus was proposed by me, several years ago, for two 
plants in the herbarium of Prof. DeCandolle, both natives of the 
province of Bahia in Brazil; its characters were sketched more than 
three years since in my synopsis of the genera of the family (huj. 
op. xiii. p. 124). One of these plants, in the size, shape, and tex- 
ture of its leaves, offers some resemblance to Chondodendrum 
tomentosum, R. & P., with which it also agrees in the more than 
usual number of its imbricately disposed sepals; but it differs 
in the form of its six petals, and in having only three stamens, 
whose filaments are united into a central column, leaving the 
anthers almost sessile on its furcated summit* ; the two cells of 
each anther are laterally imbedded in the nearly obsolete points 
of the filaments, the intermediate connective being very shortly 
and obtusely excurrent beyond their apex; and they burst by a 
* This feature of the agglutination of the stamens suggested the generic 
name, from derds, ligatus; avijp, mas.
