SMILACACEAE. 71 



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

 Staminate flowers without an ovary. Pistillate flowers usually smaller than the 

 staminate, usually with 1-6 abortive stamens. Berry black, red or purple 

 (rarely white), with 3 strengthening bands of tissue running through the outer 

 part of the pulp, connected at the base and apex. Embryo lying under a 

 tubercle at the upper end of the seed. [Ancient Greek name, perhaps not 

 originally applied to these plants.] About 225 species of wide distribution, 

 most abundant in tropical America and Asia. Type species: Smilax aspera L.

Woody, climbing or trailing, armed with short hooked prickles or nearly 

 unarmed, 1-4 m. long, the branches angled, often zigzag. Leaves coriaceous, 

 oblong to ovate or suborbicular, spinulose-dentate or entire, 2-12 cm. long, 

 reticulate-veined, 3-7-nerved, obtuse, mucronate or emarginate at the apex, 

 rounded, narrowed or subcordate at the base, the petioles 10-18 mm. long, the 

 stipular sheaths about half as long as the petioles ; peduncles about as long as 

 the petioles, 4-30-flowered ; pedicels about 4 mm. long; flowers 2-3 mm. broad, 

 the staminate somewhat larger than the pistillate; sepals and petals oblong; 

 berries black, subglobose or ovoid, 4-6 mm. in diameter. 



Rocky and sandy soil, througliout the archipelago from Abaco and Great 

 Bahama south to the Caicos and Inagua : — Florida ; Cuba ; Hispaniola. Our field 

 observations, and specimens, sliow that the synonyms cited above are of no value 

 in differentiating tlie large number of races which constitute this species : there 

 being a wide range in leaf-form and venation and in the relative number of prickles ; 

 also in the relative leafiness of the upper parts of the plants; individual specimens 

 may be unarmed. Hitchcock referred a part of his specimens of this species to 8.

Smilax Beyrichii Kunth, Enum, PI. 5: 207. 1850. 



A glabrous vine, often 5 m. long or longer, trailing or climbing, the

 to ovate, chartaceous, 2-10 cm. long, abruptly short-pointed, narrow or obtuse 

 at the base, often dilated or auricled below, shining, coarsely reticulate-veined, 

 the stout petioles 6-10 mm. long; peduncle 3-12 mm. long; pedicels several or 

 many, slender, 4-10 mm. long; flowers yellowish-green, fragrant; sepals and 

 petals of staminate flowers nearly linear, 4-5 mm. long, those of pistillate
