If you post a picture of your plant, it should be easy to identify. I'm guessing if it's budding now, it's probably an Easter cactus (which has now been classified as a Hatiora).
I have two NOID Easter Cactus and I just figured out this past year how to get them to bloom. It requires a stay in a very cool basement or other unheated room. I have a blood red one and a fuschia purple one that are loaded with buds right now. They should be blooming in the next week.
I did a science experiment on the fuschia purple one last year. I soaked it for 24 hours in a colchicine solution to see if I could mess with the ploidy. I don't know if it worked, but the original plant dropped it's segments every time you looked at it, and the treated plant hangs onto them for dear life! LOL! I don't have the original plant to compare the treated one to, as it literally dropped all of it's segments and died.
