I bought this tuber loose from a display box that said Arum something (I washed the bit of the paper with the name on). It is a long (7cm) thinnish (2cm) tuber that has grown shoots from both ends. My gut feeling is Arisaema.
I know that it is a bit of a big ask but here are the photos...............

Thanks for looking.

Pretty sure these are young Sauromatum venosum

Yes I agree - they look very much like Sauromatum venosum sometimes referred to as Arum cornutum.

Maggi that's one impressive list of aliases! :o I hope mine flowers this year. It's only a baby.

Arum cornutum was the label - thanks!
Looking at it from above today the leaves have taken on the more rounded arrangement.
It was an impulse buy when the owner said I could take the last two tubers for a pound ;D
Stars, all of you!

It won't flower this year for you. I have them in my garden for many years and they do well, frost hardy. They start with a flower in spring, just on the surface, dark red-brown, attracting flies and spreading a bad smell.... nice plants though...

Talking of bad smells, in the Auckland Botanic Gardens apparently a week ago, the huge giant whatever-it-is, about 2 metres or so I believe, opened to the horrified amazement of the locals. You know the one I mean, that stinks like rotting flesh. People came from miles around to see it. It does flower quite regularly, every couple of years or so.

The Titan Arum at Edinburgh RBG is 13 years old and is about to open its first flower : http://stories.rbge.org.uk/archives/15573 (http://stories.rbge.org.uk/archives/15573) and here

I went to see the one in the Auckland Domain when it first flowered nearly two years ago. Not a good description of an inflorescence though. http://www.stuff.co.nz/auckland/69430894/wintergarden-corpse-flower-fully-open-even-stinkier (http://www.stuff.co.nz/auckland/69430894/wintergarden-corpse-flower-fully-open-even-stinkier)
