The flowers of this genus are nearly the same as in Entada 

 and Prosopis, but constantly pedicellate, and rather larger 

 than in Entada. The fruit is not very different from that 

 of Piptadeniaf but the thick seeds with a short funicle are 

 not to be found in any of the four preceding genera, and the 

 pedicellate flowers give it at once a distinct habit.
