DIANDRIA MONOGYNIA. Divijion the Third. Such as have irr~ular corollre, and naked feeds .. VERBENA. THE calyx of the Verbena ~s a tubu~ated, .angular, linear perianthium, . compo[ed of a fingle leaf, marked w1th five mdentmgs at the verge, and the fifth denticle truncated. This cup is permanent. The corG>lla confifts of a. fingle .Pe~al :. the tube is cylindric, firait, and· of the length. of the ~up. ~he extremtty. of !t ts dilated and incurvate: the limb is patent, and lightly divided mto five femtorb1cular and equal fegments. The filaments are four in number, but ufually two of them want antherre, and ferve to no purpofe in generation. The filaments are all lhort, and buried within the tube ; the two naked ones thorter than the reit. The germen of the pifiil is fquare, the fiyle is fimple, capillary, and of the length of the tube: the fiigma is obtufe : the feeds are either two or four in number, after every flower; and they lie naked or with a very thin and fcarce difiinguilhable covering in the calyx. This g~nus comprehends the Verbena of Tournefort and others; the Sherardia of Vaillant; the Blairia of Houfion; the Kempfera of Houfton, and the Valerianelloides of Boerhaave. In the Sherardia, the anthera~ are only two, and the feeds in like manner two : in the Blaira, the antherre are two, the feeds echinated, and the calyx inflated : in the Verbena of authors, the antherre are four in number, and the feeds obtufe: in the Kempfera, the :fiamina are two, and the calyx has four acute fetre. 1.

The root of this fpecies is oblong, white, of the thicknefs of a large packthread, and of a bitter tafie : the plant rifes to two feet in height ; the fialk is fquare, and very rigid and firm, a little hairy, and fomewhat branched. The leaves fiand in pairs, at fmall difiances on the :fialk; they are a little hairy, and of a dufky green colour: they are oblong, and very deeply finuated, fomewhat in the manner of oakleaves ; the two loweft finus's are always larger, and deeper than any of the others. In the alre of the leaves, and at the top fialks, fiand very long and thin fpikes of flowers. The colour of the flowers is a pale blue, and they are very fmall.

This is a very robufi plant: it grows to four feet high; it's root is white, thick, and oblong; it's ftalks are fquare, rigid, and fomewhat hairy : four or more of thefe arife from the fame root, and, each of them dividing into many branches, the whole plant has a very builiy appearance. The leaves fi~nd in pairs, oppofit~ to one another, at (mall difiances; they have moderately long ped1cles; they are two mches and a half in length, and an inch and half in breadth in the broadeft part : they are of a dufky green colour, largeft near the bafe, and terminate in a point; they are of a rigid firuc., ture, and very deeply laciniated. The flowers are much larger than thofe of the former fpecies, and of a pale blue;, they fiand in.lon.g, thin fpikes. This fpecies is a natiye of Spain an? Port~gal.

The ihort-fpiked, nettle-leaved, American Vervain. 2. The narrower-leaved, American, nettle-like Vervain, with ll10rt fpikes, and purple flowers. 3· The white-flowered, narrower, nettle-leaved, Atnetican Vervain, with long fpikes. 4· The broad-leaved, tall, Portugal Vervain. 5· The fine-leaved Vervain. 6. The fmall, green-leaved Vervain, flowering at the joints. 7. The American Vervain, with numerous fpikes, and very narrow, nettlelike leaves. 8. The lanceolate, amplexicaule leaved Vervain, with fafciated fpikes. 9· The long and thin-fpiked Vervain, with haftated leaves. 1 o. The thin-fpiked Vervain, with undivided, ferrated leaves. Of all thefe fpecies, not one, except the firft, is a native of England. Vervain is a cephalic and carminative; it is good in head-achs, nervous complaints of aU kinds, and in obftruCl:ions of the vifcera. It is greatly reeommended alfo by fome in difeafes of the breaft and lungs. L Y C 0 P U S. THE calyx of the Lycopus is a tubulated perianthium, compofed of one leaf, and lightly divided at the end into five .narrow ,and pointed fegments. The corolla confifis of a fingle petal: the tube is cylindric, and of the length c;>f the cup : the limb is divided into four parts, obtufe and patulous ; the fegments are nearly equal in length; the upper one is broad and emarginated, the lower one fmaller. The fiamina are two filaments, longer than the corolla, and inclined towards it's upper fegment. The antherre are fmall: the germen of the pifiil is quadrifid : the fiyle is capillary, firait, and of the length of the fiamina : the ftigma is bifid and reflex. There is no fruit, but the feeds are four after every flower, and are lodged in the cup. This genus comprehends the Lycopus of Tournefort, and the Pfeudomarrubium of Rivinus. 1.

It fends down fibres in great abundance, and from the feveral parts of it there rife a great number of fialks. Thefe fiand fingly: they grow to be three feet high, and are fquare, green, hairy, and hollow : they ufually fend off fome, but not many, branches. The leaves fiand in pairs, on the fialk, at [mall difiances : they are oblong, of a pale green colour, very rugofe, and deeply ferrated about the edges; they terminate in a point. They have no pedicles, and the lower ones are ufually fomewhat divided, ef .. pecially toward the bafe; the reft are only ferrated~ The flowers grow in clufters round the ftalks; at the infertions of the leaves, they are fmall, white, and remain but a little time on the plant. The cup remains long, and contains the feeds. This |
