Sansevieria ID confirmation please!

I got this Sansevieria free in IKEA 2 years ago as it had fallen out of its pot, was very small and had no roots.I nurtured it and after a year it had some roots and began to grow.
This year it has done very well and been repotted.
It had no label but is a Sansevieria but which one?
I have plumped for 'Fernwood'.Could anyone confirm that is correct please?
Thanks in advance.

 

Here is a photo of when I first got it.
(The stones are to keep it upright as it had no roots!)

 

Lots of the cultivars look very similar but it does look the same as what I bought as fernwood mikado some years ago. It started out cylindrical but the new grow has the flattened top, like yours shows.

 

Thanks.Nice to know what a plant is!
