which have grown fingle, and are of

 AMBROSIA. 



The Charadlers are ; 

 It hath Male fiofculous Flowers, 

 which are produced on feparate Parts 

 of the fame Plant from the Fruit, 

 and have no wfible Petals : the Fruit, 

 which fucceeds the Female Flowers, 

 is foaptd like a Club, and is prickly, 

 containing one oblong Seed in each. 



The Species are ; 



1. Ambrosia maritima. C. B. 

 The maritime, or Sea-ambrofia. 



2. Ambrosia maritima, arte- 

 mifig foliis ir.odoris, elatior. H. L. 

 Taller unfavoury Sea-ambrofia. 



3. Ambrosia Canadenjn altijjima 

 hirfuta, plataiii folio. Tourn. The 

 t.illeft Canada Ambrofia, with rough 

 Plane-tree- leaves. 



The hrft of thefe Sorts may be 

 fown early in the Spring, in a Bor- 

 der under a warm Wall or Pale, 

 where it will come up very well ; 

 and when thePlants are ltrong enough 

 to remove, they may be planted into 

 the like warm Borders, where they 

 will flower, and perfect their Seeds 

 in Autumn ; but if they have not a 

 good Pofition, they feldom produce 

 good Seeds in this Country. 



The fecond Sort is very common 

 in the Weft* Indies, where it grows 

 as a Weed, and is feldom regarded 

 by the Inhabitants ; but in Europe it 

 is preferved in the Gardens of the 

 curious for Variety. This Plant fre- 

 quently comes up in the Earth which 

 is brought over from Barbados, and 

 the other Illands ; and if the Plants 

 are brought forward in the Spring, 

 they will perfect their Seeds very 

 well. 



The Seeds of this Plant mould 

 be fown on a moderate Hot-bed in 

 March ; and when the Plants are 

 come up two Inches high, they muft 

 be tranfplanted into another mode- 



rate Hot-bed, allowing each Plant 

 three or four Inches fquare j ob- 

 ferving to water them pretty well, 

 and (hade them until they have taken 

 new Root. When the Plants are 

 grown pretty ftrong, they muft be 

 taken up with Balls of Earth to 

 their Roots, and planted in large 

 Pots fiird with rich Earth ; and if 

 they are plac'd on a very moderate 

 Hot- bed until they are well rooted, 

 it will greatly forward their flower- 

 ing. Toward the Latter - end of 

 May they fhould be plac'd abroad 

 with other hardy annual Plants, 

 among which they will make a Va- 

 riety. 



The third Sort is a Native of 

 North-America, where it is a very 

 common Weed. This often grows 

 eight or ten Feet high ; and if it is 

 planted in a rich moift Soil, or is 

 often watered, it will grow much 

 higher, and fpread out into many 

 Branches. The Seeds of this Plant, 

 when fown in the Spring, feldom 

 come up the firft Year, but fre- 

 quently remain in the Ground'until 

 the following Spring ; fo that when 

 the Plants do not come up, the 

 Ground mull: not be difturb'd till 

 after the Spring following, to wait 

 for the Plants coming up. When 

 the Plants come up, fome of them 

 may be tranfplanted into a moift rich 

 Soil, allowing them at leaft four or 

 five Feet room every Way, and they 

 fhould be fhaded until they have 

 taken new Root ; and if they are 

 frequently watered in dry Weather, 

 they will grow to a large Size ; 

 but their Branches muft be fupport- 

 ed by Stakes, otherwife they are 

 very fubject. to break with ftrong 

 Winds. The flowers of this Plant 

 are not more confpicuous than thofe 

 of the Hemp, to which this is near 

 akin; therefore is only preferved 

 by fuch Perfons as are curiou5 in 

 Botany,
