The Ranunculus auricomus aggregate consists of many different apomictic
and therefore rather isolated microspecies.
Within the aggregate Ranunculus geraniiformis is counted to the biformis group,
to which some more microspecies with similarly formed basic leaves are belonging, too.
Since these leaf forms are rather similar to those of Ranunculus quinatus it carried the provisional
working name Ranunculus quinatoides when it wasn't described yet. F. G. DUNKEL described it in
Ber.By.Bot.Ges.85 (2015) as Ranunculus geranioides, however this name had previously been used
for another Buttercup, so the author had to rename it in Ber.By.Bot.Ges.86 (2016).
The blossoms have a rather full circle of petals.
Most of the microspecies generate a series of seven different forms of basal leaves in spring, as well as a summer leaf, which again has a different form.
The two or three middle ones of the spring leaves, which have the most complexe forms of all these leaves, shall be sufficient for determination of the species.
However most single plants are not developing all types of leaves, especially weak plants are often lacking the most complex middle ones of the spring leaves,
this may impede the determination.
If it was possible to determine the generation of shown leaves, the number is given in
square brackets [ ].
