I took over the care of our apartment building's lobby plants a little over a month ago, and I have identified most of them so far, except this one. This is a side view; following is a better view of the leaves, from the top.

I must be doing something right so far, because it had two leaves when I started, and its fourth is now unfurling. To be sure of the proper care and feeding, however, it would help to know what it is called!
