1. Smilax glaüca Walt. Stems terete, high-climbing, armed with straight or 
slightly curved spines, the branches angled, commonly unarmed : leaf-blades broadly ovate, 
3-15 em. long, abruptly pointed or cuspidate, entire, glaucous beneath, 5-7-nerved, rounded 
- or cordate at the base ; petioles 6-12 mm. long: peduncles 1-3 cm. long: pedicels 6-12, 
4-8 mm. long: sepals and petals greenish, linear-oblong or slightly broadened upward, 4 
mm. long: anthers mostly shorter than the filaments: berries subglobose, mostly 6-8 mm. 
in diameter, bluish black, lustrous under the glaucous coating. 
In sandy soil, Massachusetts to Kansas, Florida and Texas. Spring and early summer. 
2. Smilax cinnamomifólia Small. Stems high-climbing, sometimes 10-15 m. long, 
sparingly armed with slender spines: leaf-blades lanceolate or ovate-lanceolate, those on 
vigorous shoots ample, normally 7-10 em. long, acute or apiculate, entire, glaucous beneath, 
cuneate to truncate at the base: stipular sheath about J as long as the petiole, usually with 
tendrils: peduncles much longer than the petioles, slender, sometimes 4-5 cm. long at 
maturity: pedicels 5-10, 6-12 mm. long: sepals and petals greenish, linear-oblong or 
slightly broadened upward, 4 mm. long: anthers mostly longer than the filaments : berries 
subglobose, about 10 mm. in diameter, bluish black, lustrous under the glaucous coating. 
In woods and rich soil, Alabama and western Florida to Arkansas and Texas. Spring. 
3. Smilax renifdlia Small. Stems elongated, climbing high over shrubs and trees, 
more or less distinctly angled : leaves numerous ; blades reniform or deltoid-reniform, 3-7 
cm. long, resembling those of Cercis, rounded and mucronate at the apex, entire, mostly 
broader than long, subcordate at the base ; petioles 5-10 mm. long : stipular sheath fully $ 
as long as the petiole, usually furnished with tendrils : peduncles of pistillate plants 10-20 
mm. long, flattened, much longer than the petioles: pedicels 16-25, 2-3 mm. long : sepals 
and petals 2 mm. long, acutish: berries black, subglobose. 
Along streams, southern Texas. Spring. 
4. Smilax hispida Muhl. Stems terete, 1-5 m. long, usually thickly armed, especi- 
ally below, with slender, straight unequal bristle-like spines ; branches more or less angled, 
sometimes unarmed : leaves numerous; stipular sheath with broad, denticulate margins, 
1-3 the length of the petiole; blades thinnish, broadly ovate or elliptic-ovate, 5-15 cm. 
long, abruptly pointed or cuspidate at the apex, 7-9-nerved, lineolate, usually erose-denticu- 
late on the margins and nerves beneath, green on both sides, obtuse or subcordate at the 
base or cuneate to the petioles: peduncles 2-5 cm. long, flattened : pedicels 10-26, slender, 
4-8 mm. long: receptacle barely 2 mm. in diameter: sepals and petals greenish yellow, 
those of the staminate flowers 4 mm. long: berries globose, about 6 mm. in diameter, often
