WTB: Ludwigia Sp. 'Guinea' and Rotala sp. 'Mini'

I know the Ludwigia Sp. 'Guinea' is pretty rare, but I'm willing to pay top dollar for a handful of stems if anyone has it.

Also looking for about 5 stems of Rotala, as I already have three that are flourishing and would like to thicken that up a bit.

Please PM or reply here with pictures and prices. I'd be eternally grateful to anyone who'd be willing to sell (especially the Ludwigia)

Thanks for looking!
