The Anatomy Book IV. 
20. §. THE Weftageof the Strings and Parenchymous Fibers to- 
gether, is heremade in the fame manner, as hath been defcribed 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: 
a1. § 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 Pala-Net. For whereas in other Plants, the Webb ismade 
betwixt the Ligwons-Sirings and the Fibers of the Parenchyma, only vi- 
fible through a Microfcope : here the faid Strings themfelves are In- 
terwoven, and the Weftage apparent tothe 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 Lignous Strings or Fibers. The 
greateft whereof fwell out above the reft 5 and like fo many Ribs, are 
obliquely produced on both hands, foas to encompafs the Sack. Along 
each of thefe Ribs, on the infide the sack , runs a {mall Whitifh Lines 
being a Thread of Aer-Veféls growing thereto. Betwixt thefe Ribs or 
larger Strings, there are others much lefs, Two or Three betwixt Rib 
and Rib, Parallelly interjected. On the infide, there is a Third Serées, 
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 thefe two laft, all the reft are moft elabo- 
rately woven into one entire and ftrong piece of Work. 


Crary. 
Of the Duration of Leaves, and the Time of their 
Generation. 
« N £vergreen, is one degree above a Plant which is 
fimply Perenzial : of This,only the Truk and Buds 
live all the Winter; of That, alfo the Expanded 
Leaves. And an Evergrow, is a degree above an 
NI fa aq Evergreen: here, the Buds and young Sprigs, do 
VR SSO NE only Zve5 there, they grow and are put forth. 
SoG SS 2. §. An Evergreen, is made fuch, either by 
the Tonghneft of the Skin, and Clofenefs or Denfity of the Parenchyma, 
whereby the Leaf is better able to endure Cold 3 as in Holly: or by the 
extream Swalnefs or Fewnefs of the Aer-Veffels, whereby the Sap is lefs 
dryed up, and fo fufficient, even in Winter, for the Nourifhment of 
the Leaf; asin Box, and Tew, as alfo Fir, and all Refiniferous Plants. 
3. §. The perpetual Growth ofa Plant, feemeth to depend chiefly 
onthe Nature ofthe Sap. For all Fuyces 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 Fuyces, and fo their growth; the Warmth of Spring is fufficient for 
many others; and for fome few, that of Winter it felf. . 
_ 4 & . AS TO the Time-wherein the Leaves are formed 3 Firft, 
it is very probable, That in thofe Plawts which have Leaves ( befides 
the Diffimilar) of Two diftin& Figures, as hath the Little Common 
Bell,
