36. Chamedaphne Semper virens 8 faliis oblongis anguftis, fol orum fafciculis 
oppofitis 2 foliorum alis. 
The Ivy-tree. 
The leaves of this plant are fhaped like thofe of the fallow, or /alix folio rotundo, and are — 
ever-green, like the ehamaedaphne : foliis tini, to which it bears a near refemblance in the ftruc- 
ture of its flowers, being monopetalous, with a ftilus and ten ftamina, which grow in {mall 
clufters oppofite to each other out of the ales of the upper leaves. The cup is alfo indented in 
the like curious manner, and of a bluth rofe-colour. 
It feems to be but of fhrub growth, not rifing above four or five feet high: this fhrub is a _ 
native of Pennfylvania, and produced its blofloms at science ane in the garden of Mr. Collinfon. 
37. Zanthoyxlum Ipinofum, 
The Pellitory, or Tooth-ach-tree. 
This tree feldom grows above a foot in thicknefs, and about fixteen feet high: the bark is 
white and very rough ; the trunk and larger limbs are in a fingular manner thick fet with pyra- 
midal fhaped protuberances pointing from the tree; at the end of every one of which is a fharp 
thorn; thefe protuberances are of the fame confiftence with the bark of the tree and of various 
‘fizes, the largeft being as big as walnuts: the fmaller branches are befet with prickles only. 
The leaves are pennated, ftanding on a rib fix inches long, to which the lobes are fet, one 
| againft another, with foot-ftalks half an inch long; thefe lobes are awry, their greateft vein 
not running in the middle, whereby one fide of the leaf becomes bigger than the other. From 
the ends of the branches fhoot forth long ftalks of {mall pentapetalous white flowers with reddith 
_ ftamina: every flower is fucceeded by four fhining black feeds contained in a round green 
ce capfula. The leaves fmell like thofe of the orange, and, as well as the feeds and bark, are 
aromatic, very hot, and aftringent ; and are ufed by the people inhabiting the fea-coafts of 
_ Virginia and Carolina for the tooth-ach, from whence it derives its name. -Thefe trees are not 
to be met with farther north than the soutisermniast parts of Virginia, nor even there but ae on 
the fea-coafts. © :
