DROSERA. T HE calyx is a one-leaved perianthium, divided into five fegments, erect, acute, and permanent : the corolla is infundibuliform; it is ~ompofed of five fuboval, obtufe petals, and is fomewhat larger than the cup : the fiamma are fiye fubu l~ted filaments of the length of the cup: the antherre are fmall; the germen 1s round1lh ; the the fi;les are five, fimple, and of the length of the fiamina; the fiigmata are fimple ; the fruit is a fuboval capfule, containing only one cell, and opening into five parts at the top; the feeds are numerous, very ~mall, and oval.~ This genus comprehends the Ros fohs, or Rorella ot authors. 1. Drofera fcapis radicatis, Joliis orbiculatis. Tbe radicated-flalked Drrfera, with roundijh leaves. ~un~ lltlb. The root is fmall and fibrofe; the leaves are roundilh, a fixth of an inch in diameter fometimes larger; ufually hollow, of a reddilh colour, and affixed to long pedicle~ : the upper furface .of the leaf is furrounded with long ~eddip1 filamen~s, and ~as fome lhorter in it's m1ddle: the upper furface of the pedicle IS alfo furmlhed with fuch . the under fide of both is fmooth ; there are drops of a clear fluid confi:antly ftanding on the furfaces of thefe leaves in the hottefi weather: the fialk is rou nd, flender, naked, and three or four inches high: the iowers are moderately large and white; they ftand in a long feries at the top of the ftalk, all one way, and each on it's own feparate pedicle. It is common in boggy places. C. Bauhine calls it, Ros folis folio rotunda. 2. Drofera Jcapis radicatis, foliis oblongis. 7he Drqfera, with radicated .ftalks, and oblong leaves. The root is fmall and fibrous; the fialk naked, .fix or eight inches high, and the flowers larger than in the former fpecies, and of a beautiful white; hey fiand in a feries on the top of the ftalk, and have lhorter pedicles than thofe of the former fpecies. The leaves are an inch and a half long, including the pedicle, which by degrees dilates into the form of the leaf, and is covered, as in the former, with reddilh hairs, and with drops of a clear fluid. It is common on our bogs. C. Bauhino calls it, Ros folis folio oblongo. Authors have defcribed other fpecies, as they call them, alfo differing in .fize, under the names of larger and fmaller Rorellre. I have given the fecond a place, as a diftinB: fpecies, in complaifance to Linnreus, who makes it fuch, and who is not apt to fwell the number of fpecies unneceifarily : but I am apt to fufpect, as he alfo feems to do, that it is only a variety of the common, round-leaved kind. CRASS U LA. T HE calyx is a perianthium, formed of five lanceolated, hollowed, acute, erect, and permanent leaves, which meet in fuch a manner, as to form a kind of tube. The c?rolla is of the infundibuliform fhape; it is compofed of five petals, the ungues of whtc~ are very long_, linear,_ firait, connivent, and joined at their bafes, and the braCl:ec:e, whtch form the hmb, oval and reflexo-patent. The nectaria are five very f~all, emarginated fquammre, annexed outwardly to the bafe of the germen : the ftatnma are five fubulated filaments, of the length of the tube, and inferted into the ungues of tl~e corolla: the antherre are fimple; the germina are five, oblong, acuminated, and termmate~ ~y fubulated fiyles, of the length of the fiamina; the ftigmata are obtufe : the frutt IS compofed of five oblong, acuminated firait compreifed capfules, opening longitudinally inwards: the feeds are numerous ~nd f~all The corolla has fometimes only four fegments. ' CrajUla The HijJory if P L A N T S. Cra.flitla caule ~ic!Jotomo, joliis linearibus, jloribus quadrifidis. The dicbot~mous-Jlalked, linear-leaved Craffula, with quadrifid flowers. The root is compofed of a multitude of white, moderately thick fibres; the fialks are round, thick, fucculent, and often purpli!h; they are divided toward the tops into two, and thefe in to two more each, and fo on to the extremities, the divifion always being thus : the leaves are very fmall, narrow, and obtufe ; the flowers moderately Ia'rge, and of a beautiful red . It is frequent in France and Germany. Vaillant calls it, Sedum minimum annuum flore tetrapetalo. ! . ) S U R I A N A. T H E calyx is a permanent perianthium, compofed of five lanceolated, acumi. nated· leaves : the corolla confifi:s of · five petals, obverfely ovate, patent, and of the length of the cup : the fiamina are five filiform filaments, fhorter than the corolla; the antherre are fimple : the germina are five, and roundilh ; the 11:yles are folitary, filiform,· ereCt,· of the length of the 11:amina, and inferted into the middle of the interior fide of the germen; the fiigmata are obtufe ; there is no pericarpium, except the crufis of the feeds : the feeds are five in number, and roundilh. It is a native of South America, and is defcribed by Plumier. S I B A L D I A. T HE calyx is a permanent perianthium, compofed of a .lingle leaf, flightly divided into ten fegments, which are equal, patent, femi-lanceolate, and alternately narrower and broader : the corolla is fmaller than the cup; it con.fifis of five oval petals, inferted ihto the cup under it's fegments: the framina are five capillary fi- laments, inferted into the cup, and ihorter than the corolla; the antherre are fmall and obtufe ; the germina are five, oval and very fhort ; the fiyles are of the length of the fiarriina, and arife from the fides of the germen ; the ftigmata are capitated ~ there is no pericarpium. The cup clofes at top, and in it's bottom holds the feeds, which are oblong, and five in number: the pifiils are fometimes duplicate in the fame plants, in which, in other flowers, they are quinate. Sibaldia foliis tridentatis. The. tridentated-leaved Sibbaldia. Jtrlfill ~tnta~ p!)pUOillt_s>. The root is woody, qblong, and perennial; the fialks are round, rigid, procum-· bent, and often get within the furface: the leaves fiand in clufiers, about the tops of the ftalks; they have• each a brown, oblong, membranaceous bafe furrounding the ftalk, femi- bifid and acute ; from this divifure grows a pedicle half an inch long, erect, flender, a little hairy, and at it's fummit fiand three leaves; thefe are vertically ovate, but with the apex cut off, hairy on both furfaces, a third of an inch in length, and terminated at the extremity by three acute denticulations : the flowers fiand ufually four together, on a pedicle of half an inch long ; they are yellow. It is frequent in the North of England, and in Denmark, Sweden, and Lapland. Sibbald, from whom Linnreus has named it, calls it, Fragarire fylvefiri affinis planta flore luteo; Ray calls it, Pentaphylloides pumila foliis ternis trifidis. 4Z Clafi |
