Hi list,

A while ago we had a thread whereby someone asked for the parentage of
Phal. Liodoro. As I recall, it never got answered because no one seemed
to know.

http://www.regalorchids.co.uk/products-phal.php

This site claims that Phal. Liodoro = Phal. Deventeriana X Phal.
violacea. If so, it would make it synonymous with Phal Sweet Memory.
It could be that they are mistaken; they do say that this phal was
registered in 1982, and so was Sweet Memory. I'm not sure if this helps
any, but thought I'd throw it out there anyway.

Cheers,
Xi
