They look to be very variable though Myriam, the location is given on the gbif site which can be seen if you zoom out of the map. The larger photo shows it doesn't have the linear pattern, and hieroglyphics are squiggly.
I found a Russian site which led me to another, it looks more like it.

On the fcbs Vriesea gigantea var. seideliana fits but it's still variable, the straight species doesn't fit.
