Julius, could you tell more about what is this new species, and what are its

I am growing a malanga that came with a purple growing tip, and it is
definitely not a X. violacium (btw, is it violacium, or violaceum??), but it
does not quite look like X.saggitifolia, either. The stems have a faintly
bluish cast to them, and the plant seems to have arrived at its final size (for
its growing conditions, which here in California seem to cause dwarfism among
big-leaved aroids), which is quite smaller than a positively identified
X.saggitifolia growing right next to it.
