ORDER 65. STFRACACE^. (STORAX FAMILY.) 



Shrubs or trees, with alternate simple leaves destitute of stipules, and per- 

 fect regular flowers ; the calyx either free or adherent -to the 2 - ^-celled ova- 

 ry ; the corolla of 4 - 8 petals, commonly more or less united at the base ; the 

 stamens twice as many as the petals or more numerous, monadelphous or poly- 

 adelphous at the base ; style 1 ; fruit dry or drupe-like, 1 - ^-celled, the cells 

 commonly \-seeded. Seeds anatropons. Embryo nearly the length of the 

 albumen : radicle slender, as long as or longer than the flat cotyledons. 

 Corolla hypogynous when the calyx is free : the stamens adherent to its 

 base. Ovules 2 or more in each cell. A small family, mostly of warm 

 countries, comprising two very distinct groups or tribes. 



TRIBE I. STYRACE^E. Calyx 4 - 8-toothed or entire. Stamens 2-4 times as many as 

 the petals : anthers linear or oblong, adnate, introrse. Ovules or part of them ascend- 

 ing. Flowers white, handsome. Pubescence soft and stellate. 



1. STYKAX. Calyx coherent only with the base of the 3-celled ovary. Corolla mostly 5- 



parted. Fruit 1-celled, 1-seeded. 



2. UALES1A. Calyx coherent with the whole surface of the 2 - 4-celled ovary, which is 2 - 4- 



wiugod and 2 - 4-celled in fruit. Corolla 4-lobed 



TRIBE II. SYMPIiOCINE^E. Calyx 5 cleft. Stamens usually very numerous: an- 

 thers short, innate Ovules pendulous. Flowers yellow. Pubescence simple. 

 3 SYMP LOCOS. Calyx coherent. Petals 5, united merely at the base. 



1. STYRAX, Tourn. STORAX. 



Calyx truncate, somewhat 5-toothed, the base (in our species) coherent with 

 the base of the 3-celled many-ovuled ovary. Corolla 5-parted (rarely 4-8- 

 partcd), large; the lobes mostly soft-downy, various in the bud. Stamens twice 

 as many as the lobes of the corolla : filaments fiat, united at the base into a short 

 tube : anthers linear, adnate. Fruit globular, its base surrounded by the per- 

 sistent calyx, 1 -celled, mostly 1 -seeded, dry, often 3-valved. Seed globular, 

 erect, with a hard coat. Shrubs or small trees, with commonly deciduous 

 leaves, and axillary or leafy-racemed white and showy flowers on drooping 

 peduncles. Pubescence scurfy or stellate. (17 2rvpa, the ancient Greek name 

 of the tree which produces storax.) 



1. S. gra 11 <li folia, Ait. Leaves obovate, acute or pointed, n-hite-tomen- 

 tose beneath (3' -6' long) ; flowers mostly in elongated racemes; corolla (J' long) 

 convolute-imbricated in the bud. Light soils, Virginia and southward. April. 



2. S. pulverulenta, Michx. Leaves oval or obovato (about 1' longj, 

 above sparingly puherulent, and scurfy -tomentose beneath ; flow s (^ long) 1 -3 to-
