Capsule chartaceous, 2-celled, crowned by the calyx, containing « 
indehiscent 1-seeded nuts; having the axis, along with the Lies 
nerves, remaining after the nuts have fallen, and therefore the er 
appears tridentate—Much branched glabrous shrubs, natives 
Brazil, with acutely tetragonal branches. Leaves opposite ta 
falsely verticillate, oblong or linear ; floral ones small. Flowe 
axillary or terminal at the tops of the branches, small, pe FS 
in spikes or fascicles. It differs from Diddia in the axis of fru 
being permanent and tridentate; and in habit.
