And though not in this order, yet how nature delighteth in this number,
and what consent and coordination there is in the leaves and parts of
flowers, it cannot escape our observation in no small number of plants.
For the calicular or supporting and closing leaves, do answer the number
of the flowers, especially in such as exceed not the number of Swallows
Egges; as in Violets, Stichwort, Blossomes, and flowers of one leaf
have often five divisions, answered by a like number of calicular
leaves; as _Gentianella, Convolvulus_, Bell-flowers. In many the
flowers, blades, or staminous shoots and leaves are all equally five, as
in cockle, mullein and _Blattaria_; Wherein the flowers before
explication are pentagonally wrapped up, with some resemblance of the
_blatta_ or moth from whence it hath its name; But the contrivance of
nature is singular in the opening and shutting of Bindeweeds, performed
by five inflexures, distinguishable by pyramidicall figures, and also
different colours.
The rose at first is thought to have been of five leaves, as it yet
groweth wilde among us; but in the most luxuriant, the calicular leaves
do still maintain that number. But nothing is more admired then the five
Brethren of the Rose, and the strange disposure of the Appendices or
Beards, in the calicular leaves thereof, which in despair of resolution
is tolerably salved from this contrivance, best ordered and suited for
the free closure of them before explication. For those two which are
smooth, and of no beard are contrived to lye undermost, as without
prominent parts, and fit to be smoothly covered, the other two which are
beset with Beards on either side, stand outward and uncovered, but the
fifth or half-bearded leaf is covered on the bare side but on the open
side stands free, and bearded like the other.
Besides a large number of leaves have five divisions, and may be
circumscribed by a _Pentagon_ or figure of five Angles, made by right
lines from the extremity of their leaves, as in Maple, Vine, Figge-Tree:
But five-leaved flowers are commonly disposed circularly about the
_Stylus_; according to the higher Geometry of Nature, dividing a circle
by five _Radii_, which concurre not to make Diameters, as in
Quadrilaterall and sexangular Intersections.
Now the number of five is remarkable in every Circle, not only as the
first sphærical Number, but the measure of sphærical motion. For
sphærical bodies move by fives, and every globular Figure placed upon a
plane, in direct volutation, returns to the first point of contaction in
the fift touch, accounting by the Axes of the Diameters or Cardinall
points of the four quarters thereof. And before it arriveth unto the
same point again, it maketh five circles equall unto it self, in each
progresse from those quarters, absolving an equall circle.
