For two years ago I bought a red Trillium from a friend, he toll me he got it from China together with several Trillium tschonoskii, for me it look like Trillium sulacatum and therefore I think my friend have planted he’s new Trillium tschonoskii above one of he’s Trillium sulcatum. Another friend was in Japan this spring and he was quite sure he saw several of this red Trillium and they call it Trillium kamarovii. I know the name “kamarovii” is a not accepted synonym name for Trillium camschatcense and it has white flower and more rhombic formed leaf. I know there are red flowered Asian Trillium; apatalon and smallii, but they have more brow/red flower and the flower is quite small. Is there any of you who have heard about an Asian Trillium as look like the American species Trillium sulcatum?

Karl,
It looks like good old Trillium erectum to me! And that would make it American/Canadian...

Speaking of Trillium tschonoskii (not an easy mouthful ;D) does anyone think this is the true species?
T tschonoskii is supposed to have small flowers - as these seem quite large, I am wondering if it the hybrid with camschatcense which I believe is called T x hagae (of which there are two forms). Does anyone have any experience with them?

I know little about trilliums, but here's T tschonoskii for comparison. Photographed in deep woodland in Bhutan a few years ago......

The trillium question is crystal clear. What has me confused is that photograph of Diane Clement. I'm not sure I recognise it at all.

I think it was taken at Edinburgh Castle on a foggy day Paddy?

As I know; the petals are white with Trillium tschonoskii and there are only one variety (var. atrorubens) where the apex of ovary is dark purple and this, only when it is in fruit. The petals with T. tschonoskii is only 1.5-3.7 cm. long and 0.5-2.0 cm. broad, not much bigger than the sepals and the form is ovate to oblong ovate rarely elliptic. It is not easy to say what species it is on the picture from Diane, but I think the petals is to big to be Trillium tschonoskii and the form of the leaves is not like T. tschonoskii, more like Trillium hagae or x hagae.

According to someone (Case maybe?) the ovary of T. tschonoskii is always white.

Thanks to all who have contributed about my Trillium. I have also had pictures of this plant posted on other sites (apologies to those also on Trillium-L who may have seen it twice)
I did get a reply from Carl Denton (holder of the UK National collection of Trillium) who thought that it was T tschonoskii. There is a purple form, which I believe is the Chinese/Himalayan form (presumably the form Dave M shows from Bhutan). I will try and post another picture of my plant before it goes over as the leaves are not so broad this year, as in the picture shown, which was taken last year. Mine this year looks nearer to yours, Karl, which is perhaps why you thought it could be something else.
