But ifthefe Vefels are ContraGed, ftandin g either in, or near the Centre, and are invefted with a Barque proportionably Thick 5 the Root ftriketh down perpendicularly, as doth that of Daydelion, Buglofs, Parfuep, &c. And therefore the faid V éls, although 7g, 7, & they are {pread abroadin the Jevel Roots, yet in the perpendienlar ones , of the fame Plant, they are always contraéted 5 as by comparing the Level and Down-right Roots of Aumi, Primrofe, Ferufalem Artichoke, Comflip, and others, is manifett, 50. §. If the Aer-Vefels are Contraéted, and Environed with a greater number of succiferous, the Root grows deep 5 that is, perpen- ~ dicular and long. (c) Perpendicular, from the Contrac tion of the Aer- (6) Petc.t Veffels ; (d) and long, from the Predominion ofthe Succiferows, which Cb Pal in their growth, are extended only by that Dimenfion, as in Liquirifh, 49, an Eryngo, &c. i 51. §.

Where the Aer-Vefels are much Jpread abroad, and alfo zuzerous, the Root oftentimes, as to its feveral parts, defcend s and afcends both at once. So Radifhes and Turneps, at the fame time,in which their nether parts decend s their upper, (where the faid Ve/éls are more loofelybraced, and fpread more abroad than in the lower parts) do Tab. 2, afcend, or make their Growth upward.
