 seed I. — A large genus of trees and shrubs, none North American. 



F. Carica. Willd. Common Fig.—Lvs. cordate, 3-5-lobed, repand-dentate ; 

 lobes obtuse, scabrous above, pubescent beneath. — Supposed to be a native of 

 Caria, Asia, although cultivated for its fruit in all tropical climes. With us it

Flowers c?, sometimes cf9. — c? Calyx 4-sepaled, with a cup-shaped, 

 central rudiment of an ovary ; sta. 4. 9 Calyx 2-leayed, persistent, 

 at length surrounding the shining, compressed achenium ; sty. 1. —

1. U. Canadensis (and divaricata. Linn.) Common Nettle. 



Hispid and stinging ; lis. on long petioles, broad-ovate, rounded or sub- 

 cordate at base, serrate, acuminate ; panicles axillary, solitary or in pairs, di- 

 varicate, mostly shorter than the petioles, lower sterile, upper fertile and sub- 

 terminal, elongated in fruit.— Damp places, U. S. and Can. Stem 2— 6f high, 

 mostly simple, flexuous at top. Leaves alternate, large (3—5' by 3—30 "^or^ 

 or less hispid both sides, sometimes nearly smooth. Lower petioles 3' long. 

 Flowers minute, in panicles which vary from 1—4' in length, the fertile pani- 

 cles about 2, nearly terminal and erect, enlarged in fruit. Aug. 



2. U. DioicA. Dicecious or Stinging Nettle. 



Hispid and stinging ; /r5. cordate, '^lance-ovate, conspicuously acuminate, 

 coarsely and acutely serrate, the point entire, petioles thrice shorter ; )?5. cf or J* 9 > 

 in branching, clustered, axillary, interrupted spikes longer than the petioles. — 

 % Waste places, common. Stem 2 — 4f high, branching, obtusely 4-angled, 

 with opposite, short-stalked leaves which are 3 — 4' long, and about J as wide. 

 Flowers small, green, in axillary clusters, of mean aspect, corresponding with 

 the insidious character of the plant. " Its power of stinging resides in minute, 

 tubular hairs or prickles, which transmit a venomous fluid when pressed."

3. U. PROCERA. Willd. Tall Ncttte. 



St. tall, simple, 4-sided, slightly hispid; Ivs. lanceolate, rough, hispid, 

 prominently 5-veined, acutely serrate ; panicles axillary, very branching, nu- 

 merous, interruptedlv spicate, lower ones sterile, upper fertile. — Borders of 

 fields, waste places, N. H., &c. Stem 3— 5f high, with a tough bark. Leaves 

 densely strigose-hispid, serratures incurved, acute at each end, or somewhat 

 acuminate at apex, 3 times longer than the petioles. Flowers small, green, in 

 glomerate panicles, on the upper part of the stem. July. — Does not sting. 



4. U. PUMiLA. Richioeed. Stinglcss Nettle. 



St. ascending, often branched, weak and succulent; lis. on long petioles, 

 rhombic-ovate, crenate-serrate, membranaceous and glabrous -Jls. ^ , triandrous, 

 in corymbed heads shorter than the petioles. — % In waste places, about build- 

 ings, and in woods, U. S. and Can. Stem fleshy, semi-transparent when grow-
