iETHUSA, A;9a!ra, beggarly, in Botany, a genus of the 

 ptntanrlria digynia clafs and order; and belonging to the 

 natural order of umbullatie or umbeUtfera: : the cliarafters are, 

 tiiat the calyx is an univerfal spreading umbel, with the 

 rays gradually ftiortening towards the middle, and the par-

tial is alfo fpreading but fmall; having no ttniyerfal inrfl. 

 lucre, and the partial one placed on the outside, and con- 

 filling only of three very long, linear, pendulous leaflets; 

 and the proper perianthium fca'Ce obKrvablc: the univerfal 

 corolla is nearly uniform, with all the flofcules fertile, and 

 the partial has the petals bent in, heart-ihaped and un- 

 equal: the ilainina are fimple filaments vvitii roundifli an- 

 thers: the piilillum is an inferior germ, and the ilyles are 

 reflex with obtufe (ligmas: it has no pericarpium, and the 

 fruit is roundilh, ftreaked and bipartile: the seeds are two, 

 roundifli, llreaked, except on a third part of the furface, 

 which is plane. There are four fpecies, viz. i. 2&.cyniipium, 

 common fool's par/ley, or leffir hemlocl, which is a common 

 weed in fields and kitclien gardens, and in a flight degree 

 poifonous. It is eafily diftinguiflied when in flower, or iu 

 July and Auguft, from true parfley and chervil, by the 

 three narrow pendent leaflets of the involucre, placed on 

 the outer part only of the umbel, and by its being a much 

 humbler plant than eitlier of the others. The leaves alfo, 

 in an earlier Itnte, are of a different form and a daiker hue, 

 and when bruifed emit in a flight degree a difagreeablc 

 venomous fmell. The fafcfl; way to avoid doubt or danger 

 is to cultivate the curled parfley. Moll cattle eat it, but 

 it is faid to be noxious to geefc. 2. IS.. Bunhis, or Mon- 

 tana, conancler-leaiied fooPs parj1c\, which is a native of 

 the Pyrenees. La Marck thinks this fpecies ihould be joined 

 to the Seseli. 3. jE. Maim, Spigucl, Mcu, or Bald' 

 money, which grows wild in the mountains of Switzerland, 

 GeiTnany, Aullria, Carniola, Italy and Spain, and alfo iit 

 the high paftures of Welhnoreland, Cumberland, Lanca- 

 fliirc, and Merionethfliire. This is the Meum athaman- 

 I'icum iu Dr. Smith's arrangement of Britilh plants, vol. i. 

 p. 308. The roots and feeds are aromatic and acrid, and 

 recommended as carminative and ftomachic in afthmas and 

 obilruftions of the lungs, in the ftone, lloppage of 

 urine, and all uterine diforders: and the infufion both of 

 I'lie roots and the feeds is fometimes given to cure inter- 

 mittent fevers both in England and amongft: the inhabit- 

 ants of tlie Alps. Spignel is alfo an ingredient in Theriaca 

 and Mithridate, and appears to be of the fame nature with 

 lovage. The difference betwixt the roots is moll confider- 

 able in the cxtra£ls by water, that of the fpignel being 

 unpleafantly bitterifli, with little or nothing of the fweet- 

 nefs of that of the roots of lovage. The fpirituous ex- 

 tratt of Spignel, more aromatic than that of the lovage, 

 is moderately warm, bitterilh and pungent. Lewis's Mat. 

 Med. Diofcorides and Galen tell us, that the too frequent 

 ufe of this medicine, or too large dofts of it, will occafion 

 violent pains in the head. It may be given m fubftance 

 from half a dram to two fcruples, or from a dram to two 

 drams in infufion. Geoffrey Mat. Med. vol. ii. p. 105. 

 4. tE. fatua, Jinc-leavcd fool's parjley, was introduced here 

 in 1781, and flowers in Auguft or September. Its native 

 climate is not known. La Marck has joined to this genus 

 the Phyllandrium mutellina of Linnxus. The firil 

 fpticies is annual, and may eafily be kept dow^n in gardens, 

 by not fufterifig it to feed ; the fecond may be propagated 

 by feeds, and flowers in July; the third and fourth are 

 hardy perennial plants, and may be increafed by parting 

 the roots at Michaelmas, or lowing the feeds foon after 

 they are ripe in July and Auguft ; and keeping the plants 

 in a fliady fituation and moift foil. Martyn's Miller's Did.
