You can use this as a chance to ask your children about their education or lives in general; to discuss recent breakthroughs in phyllotaxis, the study of mathematical patterns in plant life; to compare with friends how many cups of coffee you drink in a day, and when in the day you drink them.

The appearance of patterns in the phyllotaxis - the arrangement of leaves, stems, seeds or similar - has been studied by many well-known scientists, including Leonardo Da Vinci.

Phyllotaxis, or Phyllotaxy, the arrangement of leaves on the stem, 67.

The cones of Hard Pines, by reason of relatively more and smaller scales and of a more conical form, attain a higher phyllotaxis and a more complex condition, two or even three orders being represented on a single cone; while the cones of Soft Pines, by reason of relatively fewer and larger scales and a more cylindrical form, are of lower phyllotaxis, with one order only more or less definitely presented.

Four quadrangular scales in mutual contact represent the condition of definite phyllotaxis.
