VEGETABLE STRUCTUPvE.

At the Head of the Root, or from the original point upwards, flioots 
3 Stalk. This arifes abfolutely and foleiy from the Fleflay Subftance of 
the Root ; not at all from the Pith, as has been fuppofed ; and tho’ this 
Rudiment of a Stalk be the original Vegetative Point in the Plant, yet we 
fee all about it inilances the moib plain and obvious, that the fime Flefhy 
Subdance is able, from any part or point whatever, to Ihoot up other 
Stalks. V/e fee upon the Root the originations of feveral Buds of diiferent 
growths, and containing the Rudiments of Flowers more or lefs advanced. 
All thefe rife plainly alfo from the Flediy Subdance j not from the Pith 
of the Root at all ; they are feparated from it by a plain greenifli line ; 
which is the Fleihy Subfance in its whole body, and is carried between 
them and the Pith. 
The Stalk rifes in the fame manner. The Flefliy Subfance of tlie 
Root fends up a thin portion, Vv'hich rifes immediately covered witii its 
three Coats, the Blea, the inner, and the outer Rind, and forms prefcntly 
the Vafcular Series, and the Conic Cluders. Thefe run up uninterrupted 
from the Root into the Stalk : but the Pith of the Root does not, nor 
poflibly can ; for the body of the Stalk is not formed of the entire thick- 
nefs of the Flefhy Subftance of the Root, but only of a part of it ; and 
the remaining part furrounds that portion of the Pith in the fame manner 
as all the reft, feparating the center of the Stalk from the central fubftance 
of the Root entirely. Fig. 2, n. 
Thus rifes the Stalk of the Anemone ; and tho’ it derives no Pith from 
the body of the Root, it quickly has one : for it is in the nature of the Flefhy 
Subftance, wherefoever it is lodged, to flioot the extremities of its VefTefs 
inward, and thefe form a Pith in the Stalk ; juft as thofe of the original 
morfel formed that in the Root \ and juft as the Flefliy Subftance formed 
it in the Fibres. The Stalks and Fibres are conftruded exadlly alike in 
this refpedl : both have a Pith, not derived from the Root, but formed 
from themfclves j and diftindl from the central fubftance of the Root ; not 
only as being difeontinuous, but as being loofer, and more fpungy : diftlnft 
equally in place and fubftance. 
In the lower part of the Stalk the feveral Coats are white and delicate, 
fo that it is hard to trace them diftindlly, except before the moft powerful 
Microfeopes ; only the Pith is plainly feparated from the reft, being loofer, 
and more fpungy. 
In a fecond ledlion, taking that part which Is juft above the ground, 
they appear very diftind: : the outer Rind is brown and tough, the inner 
Rind is purplifh and fpungy, but thinner than in the Root. Next comes
