or rarely exserted. Ovary S-cclled, witli several ovules in eaclicell; style 

 usually simple at first but splitting at the base as the flowering advances; 

 stigma capitate or minutely 2-lobed. Capsule globular or ovoid or com- 

 pressed, usually truncate or 2-lobed at the top, opening along the inner 

 margins of the lobes or carpels. Seeds small, ovoid or globular. — Herbs 

 usually small or slender. Leaves opposite, without stipules. Flowers small, 

 usually white, often yellowish at the throat, rarely all yellow, either solitary 

 in the upper axils or the upper pedicels crowded into a terminal cluster or 

 irregular umbel without bracteoles. 



The genus is chiefly Australian, represented in tropical Asia by three speciRs, of wnicli 

 two, or perhaps all three, are identical with Auatrahan ones; the other Australiaa species 

 are all endemic.
