This is early Spring colouration (usually too cold to come out and check hostas) so missed this one for 20 years!
According to Mark Zilis in his wonderful Hosta Handbook, this cultivar, with its unusually splotched early foliage, is either "one of the most beautiful hostas ever developed or something that induces itching"
The splotching "is not caused by a virus but is a genetic trait". There are in fact a couple of seedlings that exhibit this characteristic.
Cynthia changes to all green after a few weeks

I finally dug up my Hosta Venusta and put it in a pot in the flower bed under my kitchen window. Now my wife and I can enjoy it every morning while I eat breakfast.

Hosta rectifolia is NOT a synonym for H. sieboldii, it is a species onto its own with several forma.

Talking about Hosta (Hosta clausa), PieterK wrote:

Seems to me this species listing should properly reflect all forms of it:
clausa var. clausa
clausa var. normalis
clausa var. stolonifera
All three are in cultivation with the most common one being var. clausa.
