URTICA. 



lindrical, in pairs, ereft. — Native of Siberia, efpecially 

 beyond lake Baikal. Miller appears to have had it at Chel- 

 fea, in 1749. A hardy perennial, five or fix feet high, 

 flowering from July to September, well compared, in its 

 foliage, to Hemp. The leaves are of a deep rich green, 

 rough with very minute points, and a few mai-ginal briftles, 

 on the upper fide ; fraooth at the back. Footjlalks half the 

 length of the leaves, armed, like ihojlem, with fcattered, 

 large, and powerful flings. Clujlers thick, an inch and a 

 half or two inches long, being about half the length of the 

 leaves with their footftalks. Floivers stnd fads very large in 

 proportion to mod of the foregoing. Calyx befet with 

 flings.

 Willd. n. 23. — " Leaves oppofite, ovate, ferrated, three- 

 ribbed. Spikes axillary, fohtary, interrupted." — Native 

 of the Society Ifles. Forjler. 



27. U. rugofa. Rugged-leaved Nettle. Swartz Ind. 

 Occ. 293. Willd. n. 24 Leaves oppofite, eUiptical, fer- 

 rated, three-ribbed, rugged. CluiUrs fliort, denfe, termi- 

 nal. Stem fimple, ereft. — Native of moift ftony places, 

 about the banks of rivers, in Hifpaniola, flowering in fpring. 

 Root annual. Stem a foot high, round, downy. Leaves 

 croffing each other in pairs, ftalked, from one to two inches 

 long, finely and regularly ferrated, rough but not flinging, 

 fomewhat plaited at the margin ; hairy beneath. Stipulas 

 large, ovate. Floivers dioecious, very minute and crowded, 

 in tufts fhorter than the ftipulas. 



28. U. repens. Creeping-ftalked Nettle. Swartz Ind. 

 Occ. 294. Aft. Holm, for 1787. t. I. f. I. Willd. n. 25. 

 — Leaves oppofite, roundifh-ovate, obtufe, bluntly ferrated, 

 three-ribbed ; entire at the bafe. Cluflers capitate, axillary, 

 ftalked. Stem fimple, creeping. — Found on the fandy 

 banks of rivers in Hifpaniola, flowering in the fpring. The 

 root is annual and fibrous. Stem a fpan long, creeping clofe 

 to the ground by means of radicles from each joint. Leaves 

 hardly an inch long at the utmoft, flightly hairy, not fling- 

 ing. Footjlalks hairy, fliorter than the leaves. Flowers 

 monoecious, in little oblong clujlers, on capillary, oppofite 

 ftalks ; much fhorter than the leaves. 



29. U. Jlolonifera. Trailing Nettle. Swartz Ind. Occ. 

 296. Willd. n. 26. — Leaves oppofite, elliptic-oblong, 

 flightly ferrated. Stem afcending, with radical runners. 

 Panicles terminal, folitary, dioecious, on flender flalks. 

 — Found on the rocky banks of rivers, among mofTes, in 

 the interior part of Hifpaniola. Root perennial. Stem 

 none, or very fhort ; in Dr. Swartz's fpecimenstwo or three 

 inches long, fimple, moft leafy at the top, fending out 

 traihng flioots from the bafe, clothed with very fmall leaves. 

 The leaves of the main flem are about an inch long, rough 

 to the touch, and rather downy, but not flinging ; the 



footjlalks about the fame length. Stipulas oblong, entire, 

 membranous, accompanying all the leaves. Floiverjlalks 

 from the middle of the crowded terminal (not radical) 

 leaves, which they exceed in length. Flowers green, fmall ; 

 the male in a roundifh denfe tuft ; female in an oblong, lax, 

 compound panicle ; on diilinft plants. 



30. U. nudicautis. Naked-ftalked Nettle. Swartz Ind. 

 Occ. 311. Willd. n. 27. Ait. n. 11. — Leaves chiefly 

 terminal, oppofite, eUiptic -lanceolate, pointed, three-ribbed, 

 entire, nearly fmooth. Stem angular ; leaflefs below. Cluf- 



ters lateral, dioecious Native of hme-ftone rocks, in the 



interior of Jamaica. Root fibrous. Stem one or two feet 

 high, nearly ereft, fcarcely branched, jointed, angular, and 

 flriated, contrafted at the joints ; its light-green colour, and 

 fmooth furface, in fome degree refembhng the ftems of fe- 

 7eral fpecies of Ep'idendrum, or their allies. Leaves chiefly 



about the top of the plant, on fhort ftalks, generally 

 fmooth and naked, one and a half or two inches long, very- 

 minutely dotted, deilitute oi Jlipulas. The uppermoft cluf- 

 ters are axillary, the refl at the joints of the flem, oppofite, 

 fmall. Flowers minute, white, crowded, very rarely mo- 

 noecious. Dr. Swartz mentions a variety, with narrower, 

 fomewhat hifpid, leaves ; longer, more diffufe, clujlers ; and 

 a lefs naked_^fm. 



31. U. lanceolata. Lanceolate-leaved Nettle. Lamarck 



n. 15. Willd. n. 28 Leaves oppofite, linear-lanceolate, 



three-ribbed, entire, nearly feffile. Cluflers capitate, axil- 

 lary, folitary. — Native of Hifpaniola. J. Martin. Poiret 

 fays this fpecies is remarkable, and very diftinft, on ac- 

 count of its narrow, linear-lanceolate, nearly fefCle, leaves, 

 lihejlems are weak, herbaceous, naked, almoft cylindrical, 

 jointed. Leaves about an inch long, and two or three lines 

 broad, fomewhat wavy at the edges ; paler beneath. By 

 the defcription, there feems fome reafon to doubt whether 

 this be diftinft from the laft, but we have feen no fpecimens 

 of it. On the other hand, nudlcauUs is in the lift of fpecies 

 unknown to M. Pourret. 



32. U. corymbofa. Corymbofe Entire-leaved Nettle. 

 Lamarck n. 17. Ait. n. 30. — Leaves oppofite, ovate, 

 pointed, entire ; unequal at the bafe. Corymbs axiUary, 

 on elongated ftalks. — Native of Guadeloupe. Bad'ier. 

 Stems very rough, with glandular points. Leaves about 

 five inches long, and three broad, one fide fhorter than the 

 other at the bafe ; their furface rough to the touch. Foot- 

 jlalks very long, but fhorter than the leaves. Corymbs each 



on a long, fimple, axiUary common ftalk, probably like our 

 peduncularis, n. 6. 



33. U. Parittaria. Pellitory -leaved Nettle. Linn. Sp. 

 PI. 1397. Willd. n. 31. Ait. n. 13. Swartz Obf. 357. 

 ( Parietaria fohis ex adverfo nafcentibus, urtics racemiferas 

 flore ; Sloane Jam. v. i. 144. t. 93. f. i.) — Leaves op- 

 pofite, ovato-lanceolatc, entire. Stem much branched. 

 Flowers dioecious. — Native of lofty mountains in the Weft 

 Indies, flowering throughout the year. Stem from two to 

 eight feet high, ereft ; fomewhat fhrubby in the lower part ; 

 much branched and herbaceous above, red, quadrangular, 

 ftriated ; the ultimate branches flender, wavy, leafy, and 

 fmooth. Leaves ftalked, an inch or inch and a half long, 

 pointed, three-ribbed, veiny, fringed, very flightly, if at 

 all, unequal in the two halves : on the fmall flowering 

 branches one of two oppofite leaves is but a third the fize 

 of the other. Footjlalks long, red, fpreading. Clujlers 

 ftalked, axillary, terminal, or oppofite to fome of the 

 leaves ; their flalks flender, coloured, ereft, fmooth, 

 quadrangular, longer than the footftalks. Flowers very 

 fmall. Seed minute, black, fhining. Such is Sloane's and 

 Swartz's plant, of which we are obliged to the latter for 

 fpecimens. It is wanting in the Linnxan herbarium. 



34. U. ciliaris. Fringed Three-furrowed Nettle. Linn. 

 Sp. PI. 1396. Willd. n. 32. (Parietaria racemofa, foliis ad 

 oras villofis ; Plum. Ic. iii. t. 120. f. 2.) — Leaves oppo- 

 fite, ovate, entire, ftrongly three^ribbed, fringed. Clufters 

 divaricated, corymbofe, much branched — Native of the 

 Well Indies, but rare. A fpecimen was given by fir Jofeph 

 Banks to the younger Linnxus. The branches are very 

 fmooth, reddifh, obtufely quadrangular. Leaves ftalked, 

 from one to two inches long, pointed, fmooth, except fome 

 fcattered and marginal wliite hairs ; the three ribs remark- 

 ably prominent beneath, and furrowed above. Clujlers axil- 

 lary, oppofite, ftalked, level-topped, widely fpreading, half 

 the length of the leaves. The fringe of the latter is far lefs 

 evident in our fpecimen, than in Plumjer's figure, and yet 

 we have no doubt of its identity.
