Family 4. STYRACACEAE A. DC. 



Storax Fa?nily. 



Flowers regular, perfect, or rarely polygamo-dicecious, clustered, 

 pubescence mostly stellate. Calyx more or less adnate to the ovary. 

 Corolla gamopetalous or polypetalous, the lobes or petals 4-8. Stamens 

 twice as many as the lobes of the corolla or petals, or more, inserted on 

 its tube or base, arranged in 1 series, the filaments monadelphous or 4-5- 

 adelphous. Disk none. Ovary partly superior, 2-5-celled; ovules anat- 

 ropous; style slender; stigma simple or 2-5-lobed. Fruit a berry or 

 drupe, or often nearly dry, winged in some genera, i-seeded, or 2-5-celled 

 with a seed in each cavity. Endosperm copious, fleshy ; embryo usually 

 straight ; cotyledons flat. About 7 genera and 75 species, mostly tropical. 



Calyx superior, its tube obconic ; fruit 2-4- winged. 1. Mohrodendron. 



Calyx nearly inferior, its tube campanulate; fruit globose or oblong. 2. Styrax. 



X. MOHRODENDRON Britton. [HALESIA Ellis, not P. Br.] 



Small trees or shrubs, more or less stellate-pubescent, with denticulate or den- 

 tate leaves, and large white slender-pedicelled drooping bell-shaped flowers, in 

 lateral fascicles or short racemes, appearing with or before the leaves . Calyx-tube 

 obconic or obpyramidal, 4-5 -ribbed, adnate to the ovary, the limb short, 4-toothed. 

 Corolla campanulate, 4-5-cleft or 4-5 -parted nearly to the base. Stamens 8-16; 

 filaments flat, more or less monadelphous, slightly adnate to the corolla. Ovary 2-4- 

 celled; ovules about 4 in each cavity, the lower ascending, the upper pendulous. 

 Fruit dry, oblong, 2-4-winged, 1-4-celled, tipped with the style and the minute calyx- 

 teeth. [In honor of Chas. Mohr, botanist of the Geological Survey of Alabama.]
