Cabo Mx bulb ID ?

[Too Many Plants!]

Saw these at our Zoetry resort property grounds. They appear to be some sort of bulb (imho), Crinum looking-ish plants. There were two different looking versions. One all green, a bit more robust, with nicer flowers. The other which there were more of have some green but are more purple-ish with fading from strong purple to weak and muddy color, and the flowers not as nice as the green specimens. Flowers were sweetly scented!
Any thoughts, solid ID's, or guesses?

[CG100]

Purple form of Crinum asiatica (asiaticum?)
