_ The genus comprises a considerable number of species, mostly common weeds in the tro- 

 pical and subtropical regions of the Old World, two of them being also found in S. America. 

 Of the five Australian species, one is the commonest over the whole range of the genus ; the 

 others appear to be all endemic. 



Calyx-segments united in a 5 -toothed calyx, at least at the time of 



flowering. Stems diffuse. Leaves ovate 1. F. Crustacea.

 usually not exceeding 6 in. but attaining nearly 1 ft. when' very luxuriant. 

 Leaves shortly petiolate, ovate, broadly crenate or almost entire, sometimes 

 almost cordate at the base, from under \ in. to about | in. long. Pedicels
