2, as a flioot or procefs of the Root, is formed for it, feparating from the 
body of the Root at a greater depth, and bejring the Germ upon its head, 
19, be. T!ie Stalks and Leaves of Black Hellebore are produced both 
thefe ways ; and the latter, as mod: analogous to the formation of the Fi- 
bres, will demand tlie fird: confideration here. 
The origin of one of the afeendant dowering Shoots is this. The Root 
being filled with nouridiment, and able to fupport more Leaves and Stalks 
than thofe which rife from its immediate Crown, a provifion is made by 
Nature for more Heads, and more Crowns from below. The fiefhy fub- 
fiance of the Root rifes into a blider within its other coats, either near the 
top, 19, b, c, or at, perhaps, two thirds of its length or depth in the 
ground, d. This is cxadly like thofe biiders which gave origin to the Fi- 
bres, only it is larger; and is directed upwards : it fwells out in the fame 
manner ; and fird forms a lump upon the furface of the Root. This 
grows from time to time larger and longer ; and indead of making its way 
downward, as the Fibre did, keeps the dircdlion upward. It reaches to 
the furface, or nearly fo, and there it terminates. A Root of Hellebore 
with fuch a procefs, full grown, i, reprefented entire at Fig. 20, and fplit 
at 21, where is alfo Ihewn a Fibre tending downwards. 
This didedlion fiiews the Shoot to be exadlly like the Fibres in fubdance 
but not in termination. All the coats of the Root are continued up the 
whole length of this procefs ; and a Pith foon arifes from the fieday fub- 
dance at the bafe of the blider, 21, a. The fiediy fubdance forms an arch 
or vault jud under the crown of this Shoot ; returning into itfelf as in all 
other parts: but the coats do not return upon themfelves in that manner. 
They terminate abfolutely in the head of the Bud, and tiiere form the fird 
rudiments of Leaves and Flowers ; every coat terminating in fome one part. 
Thus we fee the fiefhy fubdance of the Root is one continuous body, fur- 
rounding it entirely ; and is didindb in the body of the Root, tho’ in part 
continued into the Shoots and Fibres. 
This is the plain and fimple formation of the afeendant Shoot or procefs 
of the Hellebore for fiowering. The Head or Crown of that Shoot form- 
ing the rudiment of the future Plant, is condruded thus. 
The outer B.irk of the body of the Root being continued to this pro- 
cefs, ends in certain Scales at its top ; fee Fig. 22, which is fomevvhat 
enlarged, Letter a. Thefe are the Scales a, in the principal Figure termi- 
nating 24, alfo the outer Rind there ; the inner PJnd terminates in certain 
other Scales, b, which are to be the outer Petals of the fucceeding Flower. 
Clofe within thefe we fee in the Crown the Vafcular Series, 22 c, which
