As I understand it, that is almost, but not quite, right. I'll pitch in what
I know here and someone more knowedgeable can follow and correct me.
There are two separate things: One is botanical terminology and one is
horticultural terminology. They are similar, but the former is more detailed
than the latter.
Family is that larger botanical category which contains all Genera, including
the Genus Iris. There are numerous subcategories between the genus Iris and
the Iris species, including those important ones not on your chart which
break the Genus down into bearded and beardless, for instance. The name of
each Species is a binomial and consists of two words: first is the name of
the Genus, then there comes a term called the Specific Ephithet, like
"siberica" in "Iris siberica". Then there may be some subdivisions below the
species like "forms." which are written after the specific ephithet.
This is how it works for "species", which are wild irises as Nature made
them, not man-made hybrids. A "cultivar" is a unique botanical entity which
is maintained and propagated for garden use, a "cultivated plant". It may be
a unique clone of a "variety" of a species, but more often the term is used
for plants resulting from human hybridizing efforts. The use of an X--called
a grex mark--in a name is an indicator that it is a hybrid between two
species or higher classifications.
I would just fill the blanks in in descending order in a descriptive way
that makes sense to you but not try to made hybrid iris cultivars--which are
unique entities but are not species-- fit into that framework too rigidly,
since they probably won't. The bearded iris BEVERLY SILLS, for instance, is
written 'Iris "Beverly Sills."' it used to be written I. germanica "Beverly
SiIls", and Iris x "Beverly Sills", but I think these are no longer correct.
About color: Here you get into the whole morass of color names and different
color systems. One way you can proceed is to visualize the color wheel which
goes RED, orange, YELLOW, green, BLUE, purple, RED. Each alternate secondary
color is a blend of the two adjacent primary colors. There can be an infinite
number of gradations around the wheel. Then there is light to dark shades on
each color, an infinite number if steps. It gets complicted and you don't
need to have to try to figure out later what you meant by
"blue-blue-violet-medium" as distinct from "blue-violet-dark." So since this
is your own database it makes sense to use descriptive color names that speak
clearly to you, like "copper" or "mouse" or "light amethyst" or "dark shrimp"
or " "baby ribbon pink--warm" or "baby ribbon pink--cool, meaning a bit
bluer", or "dingy cream" or " light canary yellow." Note many I've mentioned
evoke a familiar physical object.
Hope this helps some.
