what is the name of this particular madagascar?

has madagascar trunk but leaves are not spiny thin like most. they are wider,all green and shiny and just grow on top umbrella like. this plant has been this small height for three years. two larger ones exact to this are tremendous and bloomed white flowers.keep being told its a madagascar but cant find one like it.

I'm not 100% clear on what you mean by madagascar?? Do you mean the Madagascar Palm, by chance? This is known as Pachypodium lamerei. The white flowers sound fantastic, I would love to see a picture of those. If you've subscribed to see comments from other people on this post, you'll probably get an answer from one of my other visitors about your plant - be patient!
