Kalanchoe 'Houghtonii seems to be the best match, though ive seen a lot of variation among the photos on this site. Like i said, mother of millions=/=mother of thousands. Mot. of . millions from what ive read is a referred to hybrid between wide and thin leaves bryophyllum species, resembling a colorful succulent nettle, where as the regular mot.of thous. is less collorfull, and stubbier too. while the name mot.of mil. is often used for tubular leaved bryophyllums(delagoense), i actually consider it inapropriate given that its leaf plantlet survival rate is smaller than the regular daigremontianum, where as the more appropriately named hybrid, is basically a relentless cloning factory(i had too pull the small plants out of other pots.....).
