Arum orientale is a highly variable
species in the same way as A. maculatum, A. italicum, &c.
Your A. orientale2 is pretty much 'typical' for the species. The image
of the spotted form is certainly an unusual plant. Did you notice if there was
any difference in the smell produced at anthesis? Other expressions have the
spadix appendix wholly yellow, or purple with a yellow stipe, or vice versa and
the spathe ranging from completely green to completely pale purple with all
Your unknown Arum is A. rupicola
from Turkey and much of the middle east through into N. Iraq & N. Iran
west of the Caspian (replaced NE of the Caspian by A. korolkowii
and SE of the Caspian by A. jacquemontii), southern Azerbaijan,
Armenia. It also occurs on Lesbos and Cyprus. This is a highly variable species
with several synonyms of which A. conophalloides and A.
detruncatum are the most often seen.

I need a bit help. In the attachment you will find some
unnamed Arum. I have no idear what it can be...
The other 2 are Arum orientale. Is it common that spathe
have different markings at this species?
My Arisaema triphyllum had brown-white spathe, but it has
got green-white spathe this year. Is this chanage he spathe color also or it
depends on the sexuality of the inflorescence?
Thany in advance!
