Re: [Aroid-l] arums + arisaema triphyllum

Hi Jani,
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 intermediate combinations.
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.
Best wishes

Dear All,
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!
