This variety is known in Europe as Lilaeopsis mauritiana.  "Maurituis"  is the name of the location where this plant was first discovered according to Tropica Plants of Denmark. This is the first time this plant has been cultivated commercially in the USA, and may be availabl for a llimited time only.  The other characteristic of this plant is the leaf is much more narrow than its more common cousin.

Warning: this plant is grown hydroponically in pots and it appears to be much taller than what it will grow to be as it spreads in the aquarium. If you have tried normal Micro sword, Lilaeopsis before, you will find this specie much easier and quicker to grow.
