the peduncles of abortive flowers sometimes indurated, enlarged, and hooked. 



Sepals 3, persistent, usually partially cohering. 

 Petals 6, hj'pogynous, in two rows, coriaceous, 

 with a valvate eestivation, sometimes imited 

 into a monopetalous corolla, very rarely absent. 

 Stamens indefinite, covering a large hj^ogy- 

 nous torus, packed closely together, very rarely 

 definite ; filaments short, more or less angular ; 

 anthers adnate, turned outwards, with an en- 

 larged 4-cornered connective, which is some- 

 timesnectariferous. Carpels usually numerous, 

 closely packed, separate or cohering, occa- 

 sionally definite ; styles short ; stigmas sim- 

 ple ; ovules sohtary, or a small number, erect 

 or ascending, anatropal. Fruit consistmg of 

 a number of carpels, which are either succu-
