An Introduction to Plant Structure and Development: Plant ...
(a) A transverse view of a shoot apex showing leaf primordia arranged in two sets
of contact parastichies, one set containing five parastichies spiraling to the left
and the other containing three parastichies, spiraling to the right. (b) Diagram of ...

Patterns in Plant Development
A transverse section of the shoot tip of Os- munda cinnamomea with the contact
parastichies drawn in. There are two sets of parastichies. One set, represented by
dashed lines in the diagram, runs clockwise from older to younger leaves, and ...

The Growth and Functioning of Leaves: Proceedings of a ...
Angle of intersection of parastichies on a cylinder; orthogonal parastichies I
suggested above that a phyllotactic pattern might be specified by citing those sets
of parastichies which are most evident, and that they may be the two which
intersect ...

Phytography as a Fine Art
For determining the principal characters of phyllotaxy it is necessary in the first
place to count out the number of parastichies belonging to each of the two most
conspicuous antidromous sets of parastichies and here we may distinguish: la.

Carbon Nanotubes and Related Structures: New Materials for ...
Erickson specified the cylindrical arrays both by their jugacy and by citing two or
more sets of 'parastichies' running through the pattern. Parastichies can be
defined as helices made up of adjacent points on the cylinder. When a pattern is
...

Handbook of Plant Science
Thus, parastichies are often logarithmic spirals or nearly so when seen in cross-
sections of shoot tips (buds) with densely packed leaves (as simulated in Figure
9) Various phyllotactic patterns can be characterized by certain ranges of R (see
...

Phyllotaxis: A Systemic Study in Plant Morphogenesis
A normal sunflower head, about 6 inches or more in diameter, will frequently
have a family of 34 parastichies winding in one direction, and a family of 55
winding in the other (see Figure 1.2). A large head may show the numbers 89
and 144; ...

Optics of Aperiodic Structures: Fundamentals and Device ...
A careful inspection of the mode profiles reveals that the class A modes have the
magnetic field maxima along the parastichies that are formed by the air cylinders
and twist in the CCW direction, while class B follows a different family of ...

Developmental Genetics of the Flower: Advances in Botanical ...
The most obvious geometrical patterns are lines from the floral center to the
periphery, formed by contiguous neighboring organs: spiral lines (parastichies),
and radial, straight lines (orthostichies) (Fig. 2). A common mistake in the
literature is ...

CGAL Arrangements and Their Applications: A Step-by-Step Guide
As the name suggests, it is possible to trace spiral curves in the pattern. These
curves are called parastichies. The parastichies winding in the same direction
around the stem with the same pitch constitute one family of parastichies, and two
...
