It looks like an Oriental lily of some type - was it fragrant and did it have leaves opposite on the stem as opposed to in whorls? There are lots of pink Orientals, it might be tough to get a name on it. BTW, I have several medium pink lilies that sometimes bloom with broken color like that, and some years don't. Not sure why they do it but it's almost always pinks.

My guess is Peruvian Daffodil, sometimes called Spider Lily. Gorgeous plant. I grow them in huge pots and winter them over in the heated garage. They are usually white, but this year I found some in pale yellow (called Sulphur). Two and half to three feet tall is normal I believe, though mine grow closer to 4'. Can't remember how to post pics here and am on my way out the door but if you search Peruvian Daffodil or Spider Lily, you'll get pics.

From the picture it looks like the flowers have their heads down, does it open down, facing more out, or more so up then falls as the flower fades, that might help in identifying it better.

Regarding horticultural selections generally (and not lilies in particular) renaming has gone on a lot over time. Especially with old varieties that have been grown frequently over large areas published accounts may list a multitude of synonymous cultivar names that have been coined by various parties. (Even some wild plants being treated by the supposedly sober realm of professional botany may rather often have been subjected to repeated publication of differing botanical names). And trademarking and patenting do not confer 100% protection of commercially "owned" plants, as some selling of what are clearly examples of such under new names fabricated by second parties does appear to occur.
