The upper picture does look like a shom but it could be a dendrobium speciosum. I grow both. The answer is in the flower...

It is a Phalaenopsis. Culture notes are in the link. AOS Phalenopsis notes

I never saw hairs on a Amaryllis bulb. I grow them in the ground in Florida. I have no idea what that is, but I would repot it in a very well draining mix. Whatever it is it stores water. The size of the bulb and the thickness of the leaves. My guess this plant likes dry conditions and high light. I would repot in a cactus type soil and move it gradually to a very bright, sunny window. Grow it dry, only water when it is completely dry. I'm guessing, but that's what I would do if it were my plant. Good luck and let us know what happens. Jane

Oncidiinae Intergeneric might be as close as you will get, unless it is a widely distributed copy (Mericlone). Google Oncidium Alliance Hybrids and look at images, you might get lucky.
