HYB: 301 -- Computerized Taxonomy
This is a bit more advanced than
the other topics we've been discussing,
But I assure you that it's meant for the =
Non-Taxonomists among you....
Many classification systems have
been used over the years. The best way
to understand them is "contrast & =
compare". Quite a chore decades ago.
I once covered a large double-blackboard
with index cards and magnets, just =
trying to trace the major divisions from =
Baker through Dykes to Lawrence.
Today's computer power makes it =
much easier. It's an iterative process.
Understanding the general systems =
makes it easier to understand the =
individual species and understanding =
the relationships among the individual
species makes it easier to see the
relationships among the various systems.
I'm just going to provide some tools. =
Your assignment will be to apply them
to those species you're most interested in.
First, learn the general hierarchy:
Notice that "Variety" does not have
the same meaning it's had in common
use. That's why we say that shows
are now staged by "cultivars" rather
If you're interested in a single species,
you can set up a very simple spreadsheet.
1. List the hierarchical terms down the
2. List the authorities across the top.
3. Fill in the blanks.
To start with a very easy one, let's take =
a look at I. mesopotamica:
It was not known in Baker's time.
Dykes classified it as
Genus Iris =
He used the term "group" rather than
subsection and described the groups
rather than naming them. So his
I. mesopotamica was simply one of =
the "Pogoniris of Syria and Asia Minor".
Lawrence classified it as:
Series Elatae =
Rodionenko classified it as:
Werckmeister classified it as:
Section Pogon =
And Mathew as
I hope this one seems so simple
and straightforward that you're =
