some type of epiphyllum ... http://www.angelfire.com/ca/SSaSSSy/Epiphyllum.html
Yes that looks like the same plant. I especially love the bright pink one on the website you provided.
u're very welcome :)! they come in numerous colors. some are so fragrant to the point it makes one's stomach hurts. i know, i used to have so many different varieties at one time. not anymore though :(. but am beginning to start all over. i got one variety, white in color.
