Baker's system, as published
in 1892, was a relatively simple
one with few divisions. I'm posting
it here because it's not as widely
available as some of the more
recent ones.
Baker divided the genus Iris into =
Subgenus I. Apogon
No beard or crest
Subgenus II. Pardanthopsis
Habits of Evansia, but having
no distinct crest.
Subgenus III. Oncocyclus
Hairy down the claw and lower
part of the blade.
Subgenus IV. Regelia
Connects Oncocyclus and
Pogoniris.
Subgenus V. Evansia
Distinct crest.
Subgenus VI. Pseudoevansia
Beard, which springs from a
rudimentary crest.
Subgenus VII. Pogoniris
Bearded.
Subgenus VIII. Xiphion
Stamens not adhering to
stylebranches.
Suggenus IX. Gyandriris
Stamens adhering to style-
branches.
Subgenus X. Juno
Inner segments of perianth
spreading, minute.
He grouped the rhizomatous as
I through VII and the bulbous as
VIII through X, but didn't accord =
them genus status.
He also broke the Pogoniris into
five groups:
I. pumila
I. biflora
I. variegata
I. germanica
I. pallida
Of course, some of the Baker species
are no longer accorded species =
status -- but Baker was the pre-Dykes
authority and understanding his
reasoning is the foundation needed
for later systems.
