Fred, you were too subtle for us. Some of us need a sledgehammer to get the point.

I found last year this Arisaema in between Arisaema kiushianum
beautiful leaves but no flower this year it flowers but sure not a
Arisaema kiushianum
Who knows this species It was in between wild collected bulbs
so they grow together with Arisaema kiushianum

Thanks

Roland, this is the Japanese Arisaema thunbergii ssp. thunbergii. Arisaema thunbergii is split into 3 subspecies: ssp. thunbergii, ssp. urashima and ssp. autumnale. Subspecies autumnale is endemic to Taiwan and is autumn flowering with a striped flower. Subspecies thunbergii and subspecies urashima both occur in Japan with the main difference being the structure of the appendix. In your picture you can see the white zone of the appendix in the spathe throat that has a rather rough, spongy structure typical for subspecies thunbergii. In subspecies urashima this surface is smooth plus subspecies urashima usually does not show this type of variegation, if any at all.

Arisaema kiushianum has a very characteristic T-shaped white zone in the back of the spathe as can be seen on your first picture of this species.

Thanks a lot Pascal
I change the name in my computer
I grow Arisaema thunbergii ssp. urashima My self
but it has not the beautiful leave pattern as this one
is this normal in Arisaema thunbergii ssp. thunbergii ??

Roland

[Pascal B]

Nope, the "normal form" has plain green leaves, a minority have these silver lined leaves. Generally ssp. thunbergii has narrower, more leathery and shiny leaves than ssp. urashima. Urashima on the other hand has more variation in the flower, particularly in the flower colour from green through to straw colored to orange forms that are highly priced in Japan. The flower is also more "open" in urashima with a broader spathe blade but fortunately all subspecies are prolific offsetters. Not to mention kiushianum that easily produces 10 bulblets per tuber.....

[bulborum]

I just have a clone from Arisaema ssp. urashima
and they don't make seeds I think it is self sterile
but multiplied fast with bulblets But a beautiful long tail from about 75 cm
I have to search for other ones maybe there is a Japanese member
who has some seeds

Arum dioscoridis cyprium (hope so)

[TheOnionMan]

I received this Arisaema sp. from Darrell Probst; I believe he collected it in China.  Can anyone suggest what species it might be?  The foliage is stunning when fully expanded.
