It appears to me that some insect or bird did a messy job of pollinating this flower. When I examined the surrounding blossoms their insides looked similar, but not quite as full of the yellow pollen as this particular sample.
This is what I might think of as an Easter Lily, but it is blooming in the wrong season for that holiday. Reminds me that so many commercially available plants are grown in greenhouses to be marketed as flowering for a certain date. Poinsettias in December come to mind.
