Family 25. SMILACEAE Vent. Tabl. 2 : 146. 1799* 



Smilax Family. 

 Mostly vines, with woody or herbaceous, often prickly stems. Leaves alter- 

 nate, netted-veined, usually punctate or lineolate, several-nerved, petioled. Petiole 

 sheathing, bearing a pair of slender tendril-like appendages (stipules ?), persistent, 

 the blade falling away. Flowers small, mostly green, dioecious, in axillary umbels. 

 Perianth-segments 6. Stamens mostly 6, distinct ; filaments ligulate ; anthers basi- 

 fixed, 2-celled, introrse. Ovary 3-celled, the cavities opposite the inner perianth- 

 segments ; ovules 1 or 2 in each cavity, orthotropous, suspended ; style very short 

 or none ; stigmas 1-3. Fruit a globose berry containing 1-6 seeds. Seeds brown- 

 ish; endosperm horny, copious; embryo small, oblong, remote from the hilum. 



Genera 3 ; species about 200, in warm and temperate regions ; only the following in North America. 



i. SMILAX L. Sp. PI. 1028. 1753. 



Rootstocks usually very large and tuberous, stems usually twining, and climbing by 

 means of the spirally coiling appendages of the petiole. Lower leaves reduced to scales; 

 upper leaves entire or lobed. Flowers regular. Perianth-segments distinct, deciduous. 

 Pedicels borne on a_ globose or conic receptacle, inserted in small pits, generally among 

 minute bractlets. Filaments inserted on the bases of the perianth-segments. Staminate 

 flowers without an ovary. Pistillate flowers usually smaller than the staminate, with an
