This, I think, is Crinum amabile. The tag has been long since lost. Some of the leaves are a little ratty right now since it got bashed around a bit by the wind in a thunderstorm last week. This one is truly a monster. You can get some idea of its size when you realize that it is planted in a 10 gallon pot. Though I've not 'unplanted' it, I'm told that the bulb easily reached the size of a basketball. Don't even ask how heavy it is when I have to lug it upstairs in the winter where it keeps me company in the front, south facing window in my office. This one has not bloomed yet, though since the other one finally bloomed this year, maybe this one will too. It gets lots of water, like the smaller one, so we're hoping it blesses us with a bloom. I have a love/hate affair with this one. If it bloomed, I would probably feel less put upon as I lug it up the stairs this fall.
