The fruit of this genus is unknown, but the general appearance of the plant as 
figured by Engler points to a very close affinity with Ceratotheca or Pretrea, 
although there seems to be no indication of central spines or lateral horns in the 
Ovary.

tube, not conniving; filaments slender, filiform ; anthers dorsifixed, 
cells parallel, dehiscing longitudinally. Disc annular, equal. Ovary 
2-celled ; cells completely divided by a spurious septum ; ovules 2 in 
each division. Fruit indehiscent, very hard, dise-shaped with 2 conical 
spines from near the centre; mesocarp ultimately with 2-4 large 
cavities. Seeds 2 in each division ; testa delicate.— Perennial, trailing 
herbs. Leaves deeply sinuate-dentate to laciniate. Flowers rose-
