plus minus obscure lilacini, raro subalbescentes. Bracteae et bracteolae 

 bene evolutae. 



Obs. I. Genus Diplotropidi Benin, e Sophoreis affine, differt floribus 

 andromonoecis, lobis calycinis imbricatis, staminibus inferne in tubum coalitis, 

 indole leguminis. 



Obs. II. Ex descriptione Benthamiana in Mart. EL Bras. XY. 1. 322 

 embryo generis nostri eandem strueturam praebet ac Diplotropis nitida Benth. 



Obs. III. Genera ill. Tulasnei l)ibracliion et Diplotropis ab. i 11. Rbnt ttath 

 immerito unita esse mihi persuasum habeo; stipulae nunc deficientes nunc 

 obviae aeque ac petalorum auriculae, et veiisimiliter structura embryonis (in 

 unica specie adhuc nota) characteres genericos sine dubio praebebunt.
