Order XVIII. STERCULIACEiE. 



. Sepals usually 5, more or less united in a toothed or lobed calyx, valvate in 

 the bud (except in a very few American species). Petals either 5, hypogy- 

 nous, free, and convolute in the bud, or none. Stamens hypogynous, united 

 in an entire or lobed tube or column. Anthers definite or indefinite, 2-ceUed, 

 adnate to the outside of the staminal column or of its lobes. Ovary free, 2- to 

 5- or 10-celled, entire or divided into as many distinct carpels, with 2 or 

 piore ovules, or very rarely a single ovule in each cell or carpel. Style en- 

 tire or divided into as many lobes as cells or carpels. Fruit a capsule or 

 drupe, or separating into distinct cocci or follicles. Seeds glabrous, with little 

 or no albumen. Embryo straight or curved. — Trees, soft- wooded shrubs, or 

 rarely herbs. Leaves alternate, either simple and pinnately or digitately 

 nerved, or compound, with digitate leaflets. Stipules rarely wanting. In- 

 florescence axillary or rarely terminal. 



An Order almost entirely tropical, and most abundant in the Old World. It might be 

 Considered as a suborder of Malvaeete, differing chiefly in the 2-ceIled anthers. 



Petals none. Flowers unisexual. 



Anthers about 15. Carpels follicular when ripe 1. Stebculia. 



Anthers 5. Carpels hard and indehisceut . . ' 2. Heeitieba. 



Petals 5. Flowers hermaphrodite. 



Calyx campanulate. Flowers in terminal cymes. Ovules 2 in each cell 3. Reevesia, 



Calyx tubular. Flowers axillary. Ovules several in each cell . . 4. Helictebes. 



1. STEBCULIA, Linn. 



Flowers usually monoecious. Calyx 5-cleft. Petals none. Stajninal co- 

 lumn in the males cylindrical, vdth about 15 anthers sessile roilnd its summit.
