36. L^. rhombsa. Rhomb-leaved Nettle. Linn. Suppl. 

 417. Willd. n. 33. — Leaves oppofite, rhomboid, entire, 

 three-ribbed, flat, about the length of their footftalks, 



which are longer than the cymofe axill.iry panicles Sent 



by Mutis from Mexico. The Jlcm is herbaceous, about a of the leaves fmooth, the under flightly downy ; yet we can- 

 foot high, much branched, fmooth, leafy. Leaves from not doubt his plant being the fame as ours. He fpeaks of 

 half an inch to an inch, or rather more, in length, and a variety with narrower, more lanceolate and pointed, leaves, 

 above half as much acrofs their middle, obtufely pointed at which has not fallen in our way. 



green, covered with very minute deprcffed briftles, as in the 

 laft, which do not interfere with their fmoothnefs to the 

 touch. Some of ihe footjalks are as long as the correfpond- 

 ing leaf; others in the fame whorl but half that length. 

 Fh-wer-Jlalks longer than the longcft. footftalks, flender, 

 fmooth, folitary, forked at the upper part, bearing feveral 

 little round tufts of Jlowers, which in our fpecimen are all 

 female, and in feed ; nor do we find any traces or remains of 

 male ones. M. Poiret in Lamarck defcribes the upper fide 



each end, fmooth and even on both fides, without flings. 

 St'tpulas ftiort, membranous, abrupt. Floiuer-Jlalks axillary, 

 folitary or in pairs, fcarcely ever fo long as the footftalks. 

 Bradeas lanceolate, membranous, at each of their fubdi- 

 vifions. Flowers crowded into little heads, fmall, monoe- 

 cious. Seeds elliptical, beaked. The whole plant refembles 

 a Parietaria. 



37. U. eiliata. Speedwell-leaved Nettle. Swartz Ind. 

 Occ. 298. Willd. n. 34. — Leaves oppofite, elliptical, three- 

 ribbed, crenate, fringed, acute at each end ; entire at the 

 bafe. Stem divaricated. Flowers aggregate, on axillary 

 ftalks, about the length of the footftalks. — pound in rocky 

 woods, in the interior of Jamaica. The Jlem is herbaceous, 

 dividing from the bafe into feveral fmooth, fpreading, 



40. \J . fafciculdtn. Tufted Nettle. Poiret in Lamarck 

 n. H) — " Leaves oppofite, ovate, toothed, on long ftalks. 

 Flowers tufted at the divifions of the panicle." — Native of 

 Carolina. M. Poiret fays this is very diftinft from the pre- 

 ceding. The leaves, like every other part, are fmooth, 

 much larger than the laft, acute, generally remarkable for 

 the great length of the fmooth {lender footjlalks. Clujleri 

 many-flowered, very denfe, crowded, aggregate and axillary, 

 hardly longer than the footftalks.— We have feen no fpeci- 

 men anfwering to this defcription, nor is the prefent fpecies 

 adopted by Willdenow or Purfli ; at leaft not by the above 

 name. 



ifl . \] . fejjilifolia. Seftile-leaved Whorled Nettle. Poiret 

 in Lamarck n. 30. Willd. n. 37. — Leaves nearly feffilc, 



afcending branches, about fix inches high. Leaves an inch lanceolate, fharply ferrated, three or four in a whorl. — Ga 



long, not unlike Verotika ujjic'tnalis in general afpect, but 

 ftiorter, on longifli ftalks, crenate rather than ferrated, mi- 

 nutely downy, not flinging. Stipulas minute, accompanied 

 by tufts of hairs. Flowers moft alFuredly axillary, not ter- 

 minal, forming a kind of umbels, in which the male ones 

 fecm to occupy the upper part. This fpecies is, as Dr. 

 Swartz obferves, totally different from the Linnasan U. 

 ciliaris, but we would beg leave to remark that their names 

 are too much alike. 



38. U. radicans. Parafitical Nettle. Swartz Ind. Occ. 

 299. Willd. 11. 35. — Leaves oppofite, ovate, crenate, (hin- 

 ing ; flightly wedge-ftiaped at the bafe. Flowers axillary. 



thercd by Conimerfon in the ifle of Mauritius. The Jlems 

 are rather woody, with flraight leafy branches. Leaver 

 moflly four in each whorl, their teeth, or ferratures, pointed; 

 both furfaces covered with fliort, whilr, not very evident, 

 hairs, fuch as are found alfo on the ftem ; the upper fide is 

 of a fine green ; the under a little reddilh. The /lowers 

 have not bien obferved, fo that the genus is preiumed from 

 the habit only.

 northern part of .lamaica, where it trails over the trunks of ing. — Native of fiftures of rocks, among the mountainous 

 trees, even to their very fummits, thriving plentifully under woods of Jamaica. A pretty little ireopiug fpecies, downy, 

 their fliade, as well as on the rotten trunks of fallen trees or minutely hairy, all over. The leaves are about half an 

 in the fame fituations ; but it rarely blon"oms. The fpread- inch in diamutcr, obtufe, bright green, crenate like thofe 

 ing Jlems are fometimes attached throughout their whole of a Chryfrifplentum ; paler beneatii. Stipulas membranous, 

 length, by ftiaggy or dowiiy radicles ; they are brittle, fub- whitifti, obtufe. C/u//cr.r from the bofoms of the uppern\oft 



divided, with many oppofite leafy branches. Leaves ftalked, 

 horizontal, obtul^i , half or three-quarters of an inch long ; 

 their upper furface covered with minute depreffcd briftles, 

 though not harfli to the touch, nor ftinging. Stipulas 

 fcarcely difoernible. Flowers minute, green, the male and 

 female ones in the fame axillary tuft.

 generally four in a whorl, on unequal footftalks. Clufters

 in the interior of .lamaica. Perennial. Stem three or four 

 inches long, fucculent, prefTed ciofe to the earth, and fixed 

 by many fmall radicles. The fliort liranches form a kind of 



axillary and terminal, on long folitary ft.ilks, fomewhat co- turf with the adjoining plants. Leaves imA\, ribbed, rather 



rymbofe. — Native of the ifles of Mauritius and Bourbon, fucculent, of a brownilh green. Stipulas ov.ite, fmall and 



hanging from the rocks in an elegant manner. The root is white. Flowers dioecious, about three to live, in lit lie tcr- 



fibrous, apparently perennial. Slims from eight to twelve minal felfile clufters ; the female ones extremely minute.
