The Anatomy of Vegetables Begun: With a General Account of Vegetation founded thereon
Grew, Nehemiah

The course of the _Sap_ thus turned, it issues, I say, in a direct Line
from the _Root_ into the _Plume_, but collaterally into the Lobes also;
_sc._ by those two aforesaid Branches which are obliquely transmitted
from the _Radicle_ into either Lobe. By which Branches the said _Sap_
being disbursed back into all the _Seminal Root_, and from thence
likewise into the _Parenchyma_ of the Lobes; they are both thus fed, and
for some time augmenting themselves, really grow; as in _Lupines_ is
evident.
Yet is not this common to all Seeds; some rot under-ground, as _Corn_;
being of a laxer and less Oleous substance, differing herein from most
other Seeds; and being not divided into Lobes, but one entire thick
Body. And some, although they continue firm, yet rise not as the great
_Garden-Bean_; in which therefore it is observable, that the two Main
Branches of the Lobes in comparison with that which runs into the
_Plume_, are but mean; and so insufficient to the feeding and vegetation
of the Lobes; the _Plume_, on the contrary, growing so lusty, as to mount
up without them.
Excepting a few of these two kinds, all other Seeds whatsoever, (which I
have observed) besides that they continue firm, upon the Vegetation of
the _Plume_, mount also upwards, and advance above the Mould together
with it; as all Seeds which spring up with dissimilar Leaves, the two
(for the most part two) dissimilar Leaves, being the very Lobes of the
Seed divided, expanded, and thus advanced.
The Impediments of our apprehension hereof are the Colour, Size and
Shape of the dissimilar Leaves. Notwithstanding, that they are nothing
else but the main body of the Seed, how I came first to phansie, and
afterwards to know it, was thus: First, I observed in general that the
dissimilar Leaves were never jagg’d, but even edg’d: And seeing the even
verges of the Lobes of the Seed hereto respondent, I was apt to think,
that those which were so like, might prove the same. Next descending
to particular Seeds, I observed first of the _Lupine_; that as to its
Colour, upon its advance above the Mould, it ever changed into a perfect
Green. And why might not the same by parity of Reason be inferr’d of
other Seeds? That, as to its size, it grew but little bigger than when
first set. Whence, as I discern’d (the Augmentation being but little)
we here had only the two Lobes: So, (as some augmentation there was) I
inferr’d the like might be, and that, in farther degrees, in other Seeds.
