The bulbous part is called a pseudobulb and lots of orchids have them. What color are the flowers? You might want to ask over in the orchid forum.

Irma that does sound like one I have I will see if it has the tag still and let u know

The flower so disappointed my gifter that he could not remember it's color. (Glenn, what color is the flower on yours?)

Tiny white flowers on some and to my surprise tiny orange on other bulbs but they were very disappointing

Hi

Since there are over 30,000 species and at least 60,000 hybrids that's a tough call lol Is it a terrestrial or epiphyte??. With a pic might be able to narrow it down to a genus lol Trying to think of orchids with "disappointing flowers . Only ones I can think of are Spiranthes even they are fantastic if you look at them with a magnfying glasslol gary

I don't have the tag any more sorry
