THALICTRUM. 



L.innseus, as recorded in Sp. PL, arc certainly dioecious, 

 about a foot high, very fmooth, with tlirice-ternate leaves, 

 whofe lobes are ufually from five to foven, blunt, and rather 

 fliaUow ; both their furfaces reticulated witii flightly pro- 

 minent veins. Panicles folitary or in pairs from the bofoms 

 of the leaves, fomewhat umbellate, on long ilalks, and often 

 accompanied by a long-ftalked lolitary ttowcr. Petals of 

 the male Jloivers white or rcddiih, ovate, ribbed, the length 

 of the very {lender numerous JiJamcnls, whofe anthers are 

 yellow, very narrow, pointed : thofe of the female Jlotoers 

 much fnudler and rounder, white or greenilh, liardly fo long 

 as the little, oval, ribbed germens. The jl'igmas are very 

 flender, and remain in a prominent, almoll capillary, form, 

 on the ovate-oblong, 'A.'m.tedi feeds.

 then twice or thrice pinnate, glaucous, incorrectly three- 

 lobed, and fomewhat cut befides. Floiuers white, ereft, 

 in an upright compound panicle. Petals ovate, rather fmall,

 — Leaflets roundifli, fomewhat heart-fliaped, three-cleft ; 

 glaucous beneath. Panicle leafy, with aggregate branches. 

 Flowers drooping. — Native of woods and bufhy places in 

 Auftria, Hungary, Mount Athos, and the north of England, 

 perennial, flowering in June and July. The late Mr. Robfon 

 of Darlington found it at Baydales, near that town, as well 

 as on the margin of Ulls-water, Cumberland. This is 

 about the fize of the laft^, but the leaves are of a darker green 

 on the upper fide, very glaucous beneath. The branches 

 of the panicle grow feveral together, from the bofoms of the 

 upper leaves, and the floiveis, at leall their /laniens, are pen- 

 dulous, with longer anthers than the preceding. The petals 

 moreover are green. In the germens znd fligmas we perceive 

 DO particular diftinftion.

hardy perennial, flowering in June and July, introduced at 

 Kew, by Mr. Hunneman, in 1789. Specimens in the 

 herbarium of Linnseus, from the Upfal garden, which he 

 fufpefted might be T. tuberofum, n. 3, appear rather to belong 

 to the prefent fpecies, which differs from the two laft in the 

 flarrownefs of its leaflets, agreeing with them in the germens 

 zn6. fligmas . The panicle is more like elatum than majus. 

 The flamens are not pendulous, but divaricated. Petals

 Flowers pendulous. — Native of various parts of Europe, 

 from Sweden to Greece, generally on a limcilone or chalky 

 foil, flowering in June and July. Our Britifli plant pre- 

 cifely agrees witii what was found in Gothland by Linnsus, 

 though he fublequently confounded " things innumerable, 

 both ijiiall and great," under T. minus. The true one is a 

 bufhy fpreading herbaceous perennial, of humble growth, 

 generally but a foot high, fmooth, of a glaucous hue, with 

 tints of violet. Leaflets rather fmall, various in breadtli. 

 Panicle moderately branched. Floiwers pendulous, though 

 the ftalks become moreereft when in feed. P^Wj elliptical, ■

 Germens and feeds fmall. Linngeus's fpecific definition,

 to any thing ever taken for the prefent fpecies. He perhaps

 Tournefort, if we are right in his fynonym, in Armenia. 

 Linnseus doubtingly cites a fynonym of Seguir, which, 

 after HaUer, we have referred to T. minus. His account of 

 the prefent fpecies, of which we know nothing, is, that its 

 habit accords with T. minus, or purpurafcens, but the leaflets 

 are fmall, but one-fixth as large as thofe fpecies, glaucous 

 like Rue or Fumitory. Stem green, copioufly panicled.

 fpecies which have drooping flowers, in the ftrufture of its 



footflalk. The leaves are repeatedly compound, as in the 

 reft ; their lateral leaflets moftly ovate, acute, and entire, 

 but the terminal, and even the uppermoft lateral ones, are 

 divided or three-cleft. Footflalk greatly dilated at the bafe, 

 with orbicular membranous wings, toothed at the margin. 

 There are alfo leffer orbicular toothed auricles, upon the 

 partial footftalks, by which mark the fpecies is eafily 

 known. Willdenoqv. We have met with nothing anfwering
