 whofe flowers have five ftamina and three ftyles, and 

 has joined them to his genus of Rhus \ but this genus

The firft fort grows naturally in many parts of North 

 America; this has alow fhrubby ftalk, which feldom 

 rifes more than three feet high, fending out Ihoots 

 near the bottom, which trail upon the ground, put- 

 ting out roots from their joints, whereby it mukiplies 

 and fpreads greatly ; fo that when it is not confined or 

 trained up to afupport, the ftalks feldom rife upward. 

 If the ftalks happen to be clofe to a wall, they emit 

 ' roots v/hich faften to the joints in the wall, and fup- 

 ' port themfelves when they are fevered from the root ; 

 and the ftalks of fuch plants will become more lig- 

 n&¥s;^Ma rife much higher, than thofe which grow 

 in thb"§r6uncf.' The foot- ftalks of the leaves are near 

 t[ Cfoot loh'g ; the leaves are compofed of three oval 

 ■ neart-lhaped lobes, which are fmooth and entire, each 

 lobe ftanding upon fhort foot-ftalks ^ the lobes are 



and three inches and a half broad j 

 the two Iide lobes are oblique to the foot-ftalk, But 

 the middle one is equal j they have many tranfverfe 

 veins running from the midrib to the borders. The' 

 flowers come out from the fide of the ftalk in loofe 

 panicles \ they are of an herbaceous colour and fmall, 

 fo make little appearance. Some plants have only 

 liiale flowers, which have five ftamina in each ; thefe 

 decay without pfdducing fruit, but upon the other 

 plants are only female flowers, which have a germen 



five inche 



3 lono;, 



and three very ftiort ftyles ; thefe are fucceeded by 

 roundifti, channelled, fmooth berries of a gray colour, 

 which inclofe one or two feeds, but thefe feeds do 



■ not srowunlefs fome male plants are near them. The 

 pjarits flower in July, and the feeds ripen in autumn. 

 This plant, whence once planted in , a garden, will 

 propagate faft en9Ugh by its trailing branches, which . 

 put out roots at every part. It. will thrive in almoft 

 any foil or fituation. 



The fecond fort grows naturally in many parts of 

 North America. The ftalks of this fort rife higher 

 than thofe. of the former ; the branches are flender but 

 ligneous ; they have a'brown bark, and are garnifhed 

 with downy leaves ftanding upon pretty long foot- 

 ftalks -, thefe are compofed of three oval lobes about 



• two inches long, and one and a half broad, indented 

 angularly, and are hoary on their under fide. The 

 male flowers, which are produced on feparate plants 

 from the fruit, come out from the fide of the ftalks 

 in clofe fliort fpikes ; thefe are of an herbaceous co- 

 lour, and have five fliort ftamina in each. 1 he re-
