Sansevieria trifasciata Laurentii
If your plant is not growing straight and tall, you probably have a Futura Sans, They only get 12 to 18 inches high and the leaves grow in a more open almost floweret form.
Laurentii refers to yellow margins. I am not positive if your plant would be called the name above the picture with futura at the end or if Futura should replace the word trifasciata. I could not find anything using the name Sansevieria futura Laurentii. Hopefully someone will come along and let us know. Pretty plant.
