Flowers. This produces its Flowers 

 in March, or early in April, and is 

 rot a defpicab'.e Plant in the moft 

 curious Gardens; efpecially when 

 the Roots are large, they often pro 

 duce twenty or thirty Flowers on 

 each. 



This Plant is ufed in Medicine by 

 the Germans, as the true Hellebore. 



AGERATUM. 



The Characters are ; 



// hath a perfonated Flower con- 

 fi fling of one Leafy the under Part of 

 which is tubulous; but the upper Part 

 is divided into two Lips, the upper 

 one being divide d into two, and the 

 under one into three Parts : the Piftil, 

 which arifes from the Flower-cup, 

 afterward becomes an oblong mem- 

 braneous Fruit, divided into two 

 Cells, in which are contained many 

 fmall Seeds. 



The Species are ; 



1. Ageratum f erratum Alplnum 

 glabrum, fore purpura fcente. Town. 

 Smooth Ageratum of the Alps, with 

 a purplifh Flower. 



2. Ageratum Americanum ere- 

 Slum fpicatum, foi e ^urpureo. Houft. 

 American Ageratum, with purple 

 Flowers growing in a Spike. 



3. Ageratum Americanum pro- 

 cumbens, gnaphalii facie, fori bus ad 

 fulicrum nodos. Houft. Creeping 

 American Ageratum, having the 

 Face of Cudweed, and the Flowers 

 coming out at the fetting on of the 

 Footftalks. 



4. Agkratum Americanum fru- 

 tfft ens, chamscdryes folio, flaribus ex 

 foliorum alis. Houft. Shrubby A?ne- 

 rican Ageratum, with a Germander- 

 leaf, and the Flowers growing from 

 the Setting on of the Leaves. 



The nrft Sort, being a Native of 

 the Alps, is very hardy in refpect 

 of Cold ; but muft have a ftrong 

 So'l, and not too much expofed to 

 the Sua : this is prppagated by 



parting the Roots : the beft time for 

 doing of thisvis in September. This 

 Plant grows very clofe to theGround, 

 and has been ufed in fome Parts 07 

 England to make Edgings for Bor- 

 ders ; but near London, where the 

 Soil is hot, and has been dunged", 

 it is very difficult to maintain this 

 Plant. It flowers in June ; but rarely 

 produces ripe Seeds in England. 



The other three Sorts were dil- 

 covered in America by the late in- 

 genious Dr. William Houftoun, who 

 lent the Seeds of thefe Plants into* 

 Europe. The Seeds of thefe three 

 Sorts muft be fown on an Hot-bed 

 in the Spring ; and when the Plants 

 are fit to tranfplant, they mould 

 be placed each into a fmall Pot filPd 

 witn light Earth, and placed into a 

 moderate Hot-bed, obferving to wa- 

 ter and fliade them until they have 

 taken Roct. In Autumn thefe Plants 

 will riower ; and if they are placed 

 in a Stove, will perfeel their Seeds 

 in Winter. They may alfo be con- 

 tinued thro' the Winter in a Stove, 

 and will flower early the following 

 Summer; fo ,that good Seeds may 

 be obtain'd by this Method ; but 

 they rarely continue longer than two 

 Summers; fo that they muft be con- 

 liantiy raifed from Seeds every Year. 



The Ageratum, or Maudlin, is 

 under the Genus of Ptarmica, where 

 it is placed by Toumefort, and to 

 which it properly belongs. 



AGNUS CASTUS. Vide Vitex. 



AGRIFOLIUM. Vide Aquifo- 

 lium. 



A GRIM ONI A. 



The Charaders are ; 



The Leaves are rough, hairy, pen- 

 nated, and grow alternately on the 

 Branches : the Calyx ( or Flower- 

 cup ) confifts of one Leaf, which is 

 divided into five Segments : the 

 Flowers have five or fix Leaves, and 

 are fonnd into a long Spike, whicJi
