Lily flowers seen at the Golden Gate Park, San Francisco on 30th Sept,14.
Light pink, large flowers.
This could be Crinum moorei, as per the link........
Lily flowers of Golden Gate Park Francisco are numerous among them majority are hybrids which is very difficult to identify, However the photograph you have uploaded may be Crinum jagus
totally agree with ...
that's what I have been trying to convey all this time, that there are so many hybrids and cultivars that a single non-diagnostic pic does not do justice  to it.
Thanks for the suggested id.
... I do understand your point.
It was just a guess from my side since the flowers looked similar.
