The Basics, Periodically Speaking

The most basic question to start this investigation is what IS a periodic table? A periodic table is "a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns."

Taken as a gourd project, the definition would a table of gourds arranged in order. Of course, the order would concern the plant family and plant order among all vegetation.  The periodic table of chemical elements involves atomic structure (as shown in the dynamic link about the elements), and the periodic table of typefaces used information surrounding the design of the font.

Gourds will have information it can use as identifiers as well. What would information be for a gourd periodic table?
