Yucca linearifolia ssp. light green

I have not offered this hybrid before and only found it once before.
It is a specimen with light green leaves, without structure in the leaf, without a clear margin, and no hair, leaf about 8/10 mm wide.
The color is bright light green. Also the new growth in culture. Very special.
Found a few kilometers from the location of ssp. Saltillo, in the flat land, a colony which was also green and clearly deviated from the normal Saltillo.
He also does not look like the Piedras Negras.
