Thalictrum ID, please

[Katrin Lugerbauer]

Hello,
the Thalictrum I'm searching the name for is about 1.8 metres tall. On the pics you see it in spring, while flowering and later, wenn it is faded. I assume for a T. polygamum it is growing too tall and the stamens (?) are too short.
Thanks, Katrin

Perhaps Thalictrum contortum?

[Katrin Lugerbauer]

Thanks Lori, but does this species grow so high? On the pictures I found it was more a tiny plant.

Various references I've found suggest that it does get that tall.

Katrin, do you remember where you got it from?

Thanks Lori for the links, you are right, there are references which match to my plant. But I'm not sure of it - I found pictures in the net, where T. contortum doesn't look similar to my plant.

Iris, it's a funny story, I got it from the Sarastro nursery, but Christian Kreß swears that he has never seen this plant before. It seems to be a mystery Thalictrum  .

This site shows comparisons of various Thalictrums species (stamen, carpel, inflorescence - click on the second through fourth illustrations), as well as a verbal description and line drawing of T. contortum (syn. T. aquilegifolium ssp. sibiricum), if that is helpful.

Oh, you've convinced me, it must be a Thalictrum contortum / aquilegifolium var. sibiricum, but its petals are missing, could that be? In my opinion my plant only has stamens and pistils. The macro picture of its flowers shows is till full bloom, not later (beside the last one)! It doens't have a 'real' flower like other Thalictrums.

Usually this plants looks like this: http://www7a.biglobe.ne.jp/~flower_world/Ranuncula/Thalictrum%20aquilegiifolium%20sibiricum.htm
