How Roots 
Of the Vegtation | Book II. 
44. §, Where the fame Aerial Veffels are Fewer,or more Contratted, 
or fheathed in a Thicker and Clofer Bargue; the Root is {mooth, and 
lefS Ramified, as in Afparagus, Peony, Dandelion. But where more 
Numerous, fheathed in a Thinner Bargue, Smaller, or more Dilated ; 
the Root is more Ramifed, or more Stringy, as in Columbine, Clary, 
Beet, Nicotian. For being, as is faid, by thefe means, more fequent 
to the Attraction of the Aer; approaching ftill nearer the circumfe: 
rence of the Barque, they at laft {trike through it, into the Earth. 
And the Parenchymous Fibres being wrapped about them, and the 
Succiferons Veffels knit to them by thofe Fibres ; (a). therefore they 
never break forth naked, but always invefted with fome quantity of 
thefe Parts as their Barque: where by, whatever Con/titutive Part ig 
in the main Body of the Root, the fame is alfo in every Branch or 
String. 
ae §. From the fame Expanfion and Pliability of the Aer-Vefels, 
the Root oftentimes putteth forth Root-Buds ; which gradually fhoot 
up and become fo many Trunks. In the Formation of which Bids, 
they are pliable and receffive all kinds of ways; being not only in- 
vited Outward, toward the Circumference of the Root, as in Root- 
ftrings, but alfo fpread more Abroad every way, fo as to make a Root- 
Bud : Where as in the faid Root-ftrings s they are always more Con- 
tracted. Which, in refpe& of the Difpofition of the Parts, is the 
principal difference betwixt the Root and the Trumk’, as hath been 
faid. (4) Hence, thofe: Roots, chiefly, have Root-Buds, which have 
the fmalleft Acr-Veffels 5 (c) thefe, as is faid, being the moft pliable 
and Expanfive. 
46. §. But becaufe the expanfivenefs of the Veffels, dependeth alfo, 
in part, upon the Fewnefs of their Braces; therefore the faid Buds 
fhoot forth differently, in divers Roofs. Where the Braces are fewer, 
the Buds fhoot forth beyond the Circamference of the Root, asin Fe- 
vufalew Artichoke; where more clofe, as in Potato’s, the Buds lie 
alittle abfconded beneath it; the Aer-Vefféls being here, by their 
Braces, fomewhat checked and curbed in, while the Barque continueth 
to fwell into a fuller Growth. 
47. §. If the Aer-Veffels are all along more equally fized, the 
Root is fo alfo, or Cylindrical; as are thofe of Eryngo, Horje-Radifh, 
Marfbmallow, Liquirih, &c. But if unequal, growing ftill wider to- 
wards the bottom of the Root; then the Root is unequal alfo: But 
groweth, asis obfervable, quite contrarily to the Aer-Veffels s not 
Greater, as They do; but {till fmaller, or pyramidally 5 as in Fenil, 
Borage, Nettle, Patience, Thorn-Apple, &c. isapparent. For the Aer- 
Veffels peing confiderably wider about the bottome of thefe Roots sthey 
there contein a more Copious Ferment : Whereby the Sap is there 
alfo more volatilized, and plentifully advanced to the Upper Parts. 
Withal, thus receiving into themfélves, and fo trafmitting to the up- 
per Parts, a more plentiful “pour, they hereby rob the Parenchymous 
Parts of their Aliment, and fo ftint them in their Growth. 



48. §. FROM THE different Proportions and Situation of the 
are diffently Parts, the Motions of Roots are alfo various. For where the Are-Veffels 
Mov'd.

are {pread abroad and invefted with a thinner Bargue 5 the Root runs 
or lies Level,as in the Jevel-Roots of Primrofe, Bifhops-meed, Anemone, ®c.
