Plants which have twelve fiamina and two fiyles in each flower. AGRIMONIA .. T HE calyx is a finall permanent perianthium, formed of a :lingle leaf, divided into five fegments, placed on the germen, and furrounded with another cup : the corolla conlifis of five plane, emarginated petals, with narrow ungues infected into the calyx : the fiamina are an uncertain number of filaments, feven, ten, twelve, or more; they are very !lender, {horter than the corolla, and inferted into the calyx; the antherre are fmall, didymous, and compreffed: the germen fiands under the receptacle; the ftyles are two; they are fimple, and of the length of the fiamina; the fiigmata are obtufe : there is no pericarpium: the calyx clofes about it's neck, and becomes hard: the feeds are two, and round. This genus comprehends the Agrimonia and Agrimonioides of Tournefort. In the Agrimonia, the exterior calyx grows to the i.nterior one, an~ the f~eds are two: ti:e fiamina from twelve to twenty ; and the fruit furrounded w1th hatrs. In the Agnmonioides, the exterior calyx is free from the inner one ; the feed is lingle, and the !lamina are u[ually feven. r. Agrimonia foliis omnibus pinnatis, fruElibus hifpidis. The Agrimonia, with all the leaves pinnated, and with hifpid fruit. :{{grintonp. The root is thick, oblong, fibrated, and of a dufk.y colour; the radical leaves are four or five inches long, and are compofed of four or five pairs of oval, ferrated pinn<e, adhering, without pedicles, to a middle rib, terminated by a fingle, larger leaf at the end: the fialk is round, robuft, hairy, ereCt, and two feet high; the leaves fiand alternately on it, and are like the radical ones, but fmaller : the flowers are large and yellow ; they fiand in a long flender fpike at the top of the plant. It is common in our pafiures. C. Bauhine calls it, Eupatorium veterum five Agri· mania. It has been ell:eemed a cephalic, but now is not ufed 2.

The root is oblong, thick, woody, and reddi{h ; the radical leaves are pinnated, but the pinnre are few, and . of a roundi{h figure; they ftand on long, hairy pedicles : the ftalks are numerous, in part procumbent, hairy, reddi£h, and ramofe; the leaves ftand alternately, and are fmall, ll1ort, and auriculated at the bafe; the flowers are fmall, few in number> and ftand at the tops of the branches; they are yellow, and quickly fade: the fruit is fmooth, and of the fize of a wheat-corn. It is a native of Italy; we have it in gardens. Tournefort calls it, Agrimonioides; C. Bauhine, Agrimonire fimilis. The other fpecies are, I. The larger-leaved, fwect-fcented Agrimony. 2.

T HE calyx is a fmall, permanent perianthium, divided into twelve hollow~ acute fegments : the corolla confi{l;s of twelve oblong, lanceolated, acute, hollow petals, a little larger than the cup : the !lamina are twelve thin, fubulated .filaments, of half the length of the corolla; the antherce are roundi{h: the germina arc twelve in number; they ftand ereCt, and are placed circularly; they terminate in the fame number of fiyles, which are patent, and have acute fiigmata : the fruit are twelve oblong, compreffed capfules, placed in an orbicular order, acuminated outwards, and opening internally : the feeds are numerous, roundia1, and finall : the number of the fiamina and of the germina is not abfolutely determinate and certain in this genus. I. Sempervivum foliis radicalibus carnojis, caulinis, imbri-catis, membranaceis, corymbo racemrfo injlexo. <!15rtat ~OUfe::: The jlejhy-leaver;l Sempervivum, with a racemous and ICtk. injlex corymbus. The root is compofed of a number of white .fibres; the radical leaves are oblong, pointed, very thick and juicy, even at the edges, and difpofed in a circular form : the ftalk is thick; fucculent, round, and ufually reddifh; it is thick befet with fmallleaves, pointed at the extremities : it grows to a foot high, and at the top divides into feveral ramifications, which turn back, and have on them a number of beautiful, pale red flowers. It is common with us on houfe-tops. C. Bauhine calls it, Sedum majus vulgare. 2. Sempervivum caule inferne nudo, lt2vi, ramo.fo. The Sempervivum, with the jtalk at the bottom naked, fmootb, and ramofe. '3tttt J)onfelttft. The root is brachiated; the ftem grows to tpe thicknefs of a man's arm, and to three or four feet high; it is naked, and of a reddilh colour, and fends off a number of branches as thick as a man's thump, which divide into others; and at the extremities of thefe fiand round clufiers of leaves, arranged in the manner of the radical leaves of the commo.(l Houfeleek; they are of a bright green colour, oblong and broad, narroweft at the bafe, and very lightly crenated about their edges, very fucculent and tender. From the center of fome of the cluflers of thefe leaves, on the upper branches of the plant, there grow thick pedicles, whicJ1 fupport !}Umbers of large, whitifhyellow flowers. It is a native of the iflanrls of the Archipelago ; it is common in our green-houfes Dodonreus calls it, Sedum arborefceps majus. Clafs the Twelfth. ICOSANDRIA. P /ants which have about twenty flamina in every flower. THE claffical character of the Icofandria is this : the calyx is always hollow, and formed of a fingle leaf: the corolla is affixed by it's ungues to the fides of the calyx; and the fiamina are affixed either to the fide of the calyx, or to the corolla: the fiamina are always more than twelve, ufually twenty, or about that number; but this is not fo determinate and certain in them, as alone to conftitute a generical charaCter.
