 LIN. SYST. Tetrandria, Monogynia. Calyx with an ovate 

 tube, and a 4-toothed limb : teeth erect, permanent, also sepa- 

 rated on the fruit by acute narrow recesses. Corolla with a short 

 tube, a bearded throat, and a 4-lobed limb; Stamens exserted a 

 little; anthers ovate or roundish, small. Capsule ovate, some- 

 what attenuated at the apex, crowned by the calycine teeth, 

 which are connivent, but separate, 2-celled, and dehiscing in the 

 middle of the cells. Seeds minute, angular, many in each cell. 

 Herbs, sometimes suffruticose at the base, with a habit like 

 that of Spermacbce. Stems tetragonal or nearly terete. Leaves 

 opposite. Stipulas adhering to the petioles on both sides, end- 

 ing in many bristles. Flowers axillary, usually glomerate. 

 This genus differs from Houstbnia, to which St. Hil. pi. rem. 

 bras. p. xxi. has joined it, in the calyx being adnate to the fruit 

 the whole length. It differs from Oldenlandia in the teeth of 

 the calyx being separated on the fruit by narrow recesses, not 

 by broad ones. 



* Pedicels axillary, \-Jlotvered, solitary, and sometimes twin.

 equal in length to the leaves ; corolla hardly longer than the 

 calycine teeth. Native of New Caledonia. Capsule downy,

 row recesses, indicating it to belong to this genus.
