2 156 i The Anatomy Book IV. 
20. $. THE Wefiageof the Strings and Parenchymous Fibers to- 
gether, is here made in the fame manner, as hath been deferibed in the 
Anatomy of the Root, and Trunk: the former being in fome Sort as the 
Warp, the latter as the Woof of the Leaf. 
21. 6. And one Example we have (it may be more than one ) 
wherein Nature fhews, though not a greater, yet a different Art; and 
that is the Palm-Net. For whereas in other Plants, the Webb is made 
betwixt the Lignons-Strimgs and the Fibers of the Parenchyma, only vi- 
fible through a Mierofope : here the faid Strings themfelves are In- 
terwoven, and the Weftage apparent to the bare Eye. Ofthefe Palm- 
Nets or Sacks, there are feveral Sorts. One of them is compofed in this 
manner. It hath a Fivefold Series of Ligwons Strings or Fibers, The 
greateft whereof fwell out above the reft; and like fo many Ribs, are 
obliquely produced on both hands, foas to encompaß the Sack. Along 
each of thefe Ribs, on the infide the sack , runs a fmall Whiti Lines 
being a Thread of Aer-Veffels growing thereto. Betwixt thefe Ribs or 
larger Strings, there are others much lef, Two or Three betwixt Rib 
and Rib, Parallelly interje&ed, On the infide, there is a Third Series, 
which is alfo obliquely produced 5 but tranfverfly to the former. The 
Fourth and Fifth, confift of the fmalleft strings ; not only Tranfverfly 
produced, but alfo Alternately, from the outfide to the infide of the 
Sack, © vice verfa. By thele two laft, all the reft are moft elabo- 
rately woven into one entire and ftrong piece of Work. 
CHARY: 
Of the Duration of Leaves, and the Time of their 
Generation. 
g N Evergreen, is one degree above a Plant which is 
) fimply Perennial : of This only the Trank and Buds 
live all the Winter; of That, alfo the Expanded 
Leaves. And an Evergrom, is a degree above an 
Evergreen: here, the Buds and young Sprigs, do 
only live; there, they grow and are put forth. 
z 2. $. An Evergreen, is made fuch, either by 
he Tongbnefs of the Skin, and Clofemejs or Denfity of the Parenchyma, 
whereby the Leaf is better able to endure Cold 3 as in Holly: or by the 
extream Smalnefs or Fewnefs of the Aer-Vefféls, whereby the Sap is leß 
dryed up, and fo fuflicient, even in Winter, for the Nourifhment of 
the Leaf; as in Box, and Yew, as alfo Fir, and all Refiniferous Plants. 
3. $. The perpetual Growth ofa Plant, feemeth to depend chiefly 
on the Nature ofthe sap. For all Juyces will not ferment alike, nor 
with the fame degree of Heat. So that whereas many Plants require a 
greater Heat, as that of Summer, for the fermenting and diftribution of 
their Juyces, and fo their growth; the Warmth of Spring is fafficient for 
many others; and for fome few, that of Winter it felf. 
4 $ AS TO the Time wherein the Leaves are formed; Fir; 90 
it is very probable, That in thofe Plants which have Leaves (belides IN 
the Diffómilar ) of Two diftin& Figures, as hath the Little Common N 
Bell,
