T HE calyx is a hollow, permanent perianthium, formed of five ovate-oblong,' obtufe leaves : there is no corolla. The !lamina are five fubulated filaments, of the length of the leaves of the cup, and placed oppofite to them; the antherre are ro.undiili : th~ germen is placed below the receptacle ; 'the fiyles are two, very fhort and ereCl:; the A:igmata are acute ' tae fruit is a capfule, plac~d within the cup at the bafe ; it contains only one cell, and is deciduous : the feed is fingle, kidney-!haped, compre!fed, and furrounded every way by ~he cup. Of this genus there is only one fpeoies ; but this, from it's varying in the colour of the ftalks, leaves, &c. from a pale whitiih green to a blood-red, and in other particulars, has been defcribed as different fpecies, under the names of Beta alba and Beta rubra, &c. BET A. Jeett. The root is long and thicl< ; oft¢n an inch and half in diameter, and more than a foot in length: the radical leaves are eight inches long, and five broad ; of a pale green, a whiti!h, or a blood-red colour: the ftalk is very thick, roundilh, ftriated, whjtilh or reddilh, and fqur feet high : the leaves ftand alternately on long pedicles on it ; they are like thofe of the root, but fmaller, and very thick and flefhy : the flowers ftand on the tops of the ftalks, and on {hort branch~s rifing from the alre of the leaves. They are fmall, and naturally of a greenia1 white. Culture makes a vail: variety in this plant ; fo that Tournefort has defcribed no lefs than ten varieties of it, under the name of fo many fpeci~s . It is a native of the fea-coafts of many parts of Europe, and, in this it's wild ftate, is defcribed, as a diftinCl: fpecies, under the name of Beta fyl vefi:ris maritima, when cultivated C. Bauhine calls it, Beta rubra, and Bet~ alba. T he variations culture makes in it are in fize, and in the roundnefs or flatnefs of the ftalk, and in the variation of the leaves, fialks, or ribs of the leaves, into red and yellow. ULMUS.- T!Je HijJory of P L A N T S. ULMUS. T H E calyx is a turbinated, rugofe perianthium, compofed of a fingle leaf, divided into five fegments at the edge, ereCl:, coloured on the infide; and permanent : there is no corolla. The fiamina are five fubulated filaments, twice as long as the cup : the anther~ are ereCt, ihort, and fulcated fou r ways : the germen is orbicular and ereCl:; the ftyles are two, ihorter than the ftamina, and reflex ; the ft igmata are hoary. The fruit is a large, oval, compreifed, drupe : the feed is fingle, roundifh, and lightly compreifed. · I. Ulmus frut!u membranaceo. The membranaceous-fruited Elm. · 1tbt conunon <&lrn. This is a large, tall and ramofe tree: the bark is rough, and full of cracks on the trunk, but on the young ihoots fmooth, and of a pale brown colour, and the under bark is mucilaginous and tough : the leaves are two inches long, nearly as much in . breadth, fetrated round the edges, and pointed at the ends : the flowers appear before the leaves; they are fmall and purpliih : the fruit is a large, oval-pointed, membranaceous drupe : the feed f weet to the tafie. It is commdn in our hedges. C. Bauhine calls it, Ulmus campeftris et Theophrafti; Dodonreus, Ulmus. I t's inner bark, boiled in water, makes an excellent mucilage, ufed in fore throats, and in fevers. The other fpecies of Elm are, 1. The narrow-leaved Elm. ,2. The broad, roughleaved Elm; 3· and the broad and fmooth-leaved Elm. BOSEA. THE calyx is a perianthium, compofed of five hollowed, lanceolated, erect leaves, thinner at the edges than elfewhere ; there is no corolla : the fiamina are five fubulated filaments, a little longer than the cup ; the anther~ are fimple; the germen is ovato-oblong, and cufpidated : the ftyles are two, and patulous : the ftigmata are .fimple : the fruit is a globofe, uhilocular berry ; the feed is fingle and acu-minated. This genus comes very near the Celtis and the Ulmus. . Of this there is but one known fpecies. It is defcribed by Ludwig, under the name of Yerva Mora. Thefe charaCters difiinguiih it fufficiently. CAESSA. T HE calyx is a perianthium, compofed of five oblong, hollow leaves. The corolla confifis of a fingle petal; the tube is ihort, and the mouth expanded : the ftamina are five fubulated filaments, placed on the upper part of the tube of the corolla ; the anther~ are .fimple : the germen is oval ; the ftyles are two, ihort and expanded : the ftigmata are thick ; the fruit is a bivalve capfule ; the feeds {mall. There is but one known fpeeies of this genus, which is fufficiently difiingui(hed by thefe characters. Clqfs the Fifth Order tbe Second. Divijion tbe Third. Pentcuzdria Digynia, with ma77:Y fieds focceeding each flower. NAMA. T g E calyx is a permanent perianthium, compofed of five oblong leaves : the corolla- confifts of five petals : the il;amina ·are .five ihort and flender filaments, of . a fubulated fo rm; the antherre are tumid and large; the germen is of an ov,al figure : the ftyles are two; they are ihort and flender: the fruit is a capfule of an oval figure, formed of two valves, and containing only a fingle cell; the feeds are numerous, fmal1, and roundiili. Of this genus there is but one known fpecies, which needs no farther defc ription. MI TRE O LA. |
