The number of turns beginning from one leaf, turning around the
stem until reaching another leaf at the same direction, and the
numbers of leaves encountered during any one complete cir-
cle gives a Fibonacci number. If we begin counting from the
opposite direction, then we obtain the same number of
leaves, but with a different number of turns. The number of
turns in both directions and the number of leaves en-
countered during these turns gives three consecutive
Fibonacci numbers.

er. The order in the arrangement of the leaves around the
stem is set out in specific numbers according to what in bot-
any is known as leaf divergence. This sequence in leaves is based on a com-
plex calculation. If N is the number of turns from one leaf around the stem

until we come to another leaf on the same plane, and if P is the number of
leaves on each turn, then P/N is referred to as leaf divergence. These lev-
els are ? in grasses, 1/3 in marsh plants, 2/5 in fruit trees (for example, ap-
ples), 3/8 in species of bananas, and 5/13 in bulbous plants. 27
The way that every tree from the same species implements the ratio
set out for its own species is a great miracle. How, for example, does a ba-

ture (left), we need to make three turns
in a clockwise direction in order to

route. Moving in an anti-clockwise di-

are Fibonacci numbers.

three turns in the other direction around

the stem. This time, we obtain the con-

plant, each leaf making a 5/8 turn
around the stem.
