Root perennial, branching. Stem 10 to 15 or 20 feet long, several from the same 

 root, slender, roluhile (twining constantly with the Sun, or Kast.Snu:MVtsi) 

 somexchat angular, and mostly heist ed, aculeately andretrorsely scabrmn, branch, 

 ing above. Leaves 3/o5 inehes long) and 2 /o 4 inches wide, generally opposite] 

 cordate at base. Globed, acuminate and srrrutc,—lhe upper ones often alternate 

 and not lobcd,—all very Scabrous on the uppet surface, sprinkled with reoinovs 

 particles b neath ; petioles I to '2 or 3 inches long ; stipules I in eur- lanceolate, a>u. 

 minate, striate, membranous. Stamlnate flowers greenish, in oblong panicle* 

 terminating the axillary branches ; peduncles opposite, somewhat cymcesiy subdi- 

 vided, brartca.'c at base : bracts resembling the stipules. Pistillate flowers in 

 pendulous ovoid-oblong amenta, tehi'h are usually very numerous, 1 U2 inches 

 long, and about an iwh in diameter; scales foliareous, or membranous, netted 

 mnd sligfdly pubescent, orate (the tower ones a nminate), imbricated, embracing the 

 floret, at base, in the infolded margin, and thickly sprinkled with redelisk-orange. 

 colored resinous particles which are highly bitter and aromatic. SeedroundUh. 

 ovoid, coated with a tawny membrane (—or rather, perhaps, a nut, with a thin

Obs. This plant -the only known spet ies of the genus, -is undoubtedly indigen- 

 ous, here,— as J hare often seen both staminate and pistillate ottcs growing in the 

 thickets along the Brandytcine. The pistillate plan! is very generally cultivated 

 for its proverbially bitter and numerous cones, or aimnis, which are so valuable 

 in brewing. These amen f s also afford a good anodyne t nature : and make an ex- 

 ceUcnt antiseptic cataplasm, for gangrenous or Unconditioned sores.
