Sepals 5 (rarely 6), persistent. Petals 5, obovate. Stamens 10: filaments 

 naked; the 5 opposite the sepals somewhat abortive, placed inside 5 hypogy- 

 nou3 glands. Ovary of 5 cohering carpels; each with 2 collateral pendulous 

 ovules, and spuriously 2-celled by a longitudinal septum (the ovary thus be- 

 ing apparently 10-celled with a solitary ovule in each cell) : style conical, 

 lU-furrowed : stigma capitate, 10-ribbed. Fruit at length separating into 10 

 one-seeded cocci, without transverse partitions. — Annual branching diiTuse 

 or trailing pubescent herbs. Leaves opposite, with interpetiolar stipules, ab- 

 ruptly pinnate. Peduncles solitary, axillary, 1-flowered.

Order XXXIII. ZANTHOXYLACEiE. Ad. Juss. 



Flowers by abortion dioecious or polygamous, regular. Sepals 3-4- 

 5, very rarely 6-9, cohering at the base. Petals as many as seoals, 

 or rarely none : aestivation twisted-convolute. , Stamens as many as 

 the petals and alternate with them, or seldom twice as many, rising 

 from around the base of the torus which bears the abortive carpels; 

 in the pistillate flowers either wanting or imperfect : filaments dis- 

 tinct : anthers introrse. Ovaries usually the same number as the 

 sepals or sometimes fewer, more or less stipitate, either distinct or 

 united: ovules 2 or rarely 4 in each carpel : styles distinct or more 

 or less connate when the ovaries are separate, mostly combined when 

 the ovaries are united. Fruit sometimes baccate or mcmbrana- 

 ceous, sometimes consisting of 1-5 drupes or 2-valved capsules ; the 

 rather fleshy sarcocarp partly separable from the endocarp. Seeds 

 solitary or in pairs, anatropous, pendulous : testa thick and crustace- 

 ous, usually smooth and shining. Embryo lying within fleshy albu-
