Indoors searching for green!

It's been a beautiful day today but I have seen it whilst I drove to work and just now when I came home. In between I have been stuck in my office attending to many jobs left undone whilst I have been away. I even had my lunch at my desk and just kept going.

On one trip down the office I was chatting to my administrator when I noticed a bit of greenery near her desk. This is a large plant which is mainly green. I do not know its name. But it has produced this lovely white flower. In the dullness of my office today it brought some of the richness of the outside. I took a few photos and now home and a little tired I thought this can be my blip.

Grateful to anyone who can identify it?
