Ophipogon Japonica? Mondo grass?

I don't recognise that scientific name from Kasselmann's Aquarium Plants book and didn't find it in the index in the back of the book. I won't say that the book has every possible plant that could be grown in an aquarium but all the common ones are.

If it is mondo grass you could try finding a place for it in your yard.

Yup,
