usually furnished with bracts 

 which are sometimes bag- shaped 

 or hooded. Sepals from 2 to 7, 

 usually coriaceous and imbri- 

 cat.il. Corolla liyiio.jvnous ; 

 sometimes monopetalous, calyp- 

 biform, entire, or torn at the 

 point ; sometimes consisting of 

 five imbricated petals. Stamens 

 usually indefinite, inserted either 

 on the receptacle or on a hypo- 

 gynous membrane : filaments 

 dilated at the base ; anthers 

 long, innate, 2-celled, bursting 

 inwards, ih.. . sup rior, 



u-ually furrowed, 3 or many- 

 oelled ; style single ; stigma tun 

 pie or capitate : ovules nume- 

 rous, attached to the projecting 

 lobes of a central plae ul . 

 cending, with the foramen down- 

 ward-. Fruit supposed to be 

 usually succulent ; but also cap- 

 sular, coriaceous, and consisting 

 of several valves which separate 

 slightly ; dissepiments proceed- 

 ing from the middle of the 

 valves, but not meeting in the 

 centre, so thai the fruit becomes 

 1 -celled. Seeds very minute and 

 numerous, nestling in pulp, [oh-

 dons, and a long conical acute radicle, which is inferior, contiguous to the hilum.
