the first looks like some kind of acacia (mimosoideae), it might be in the mimosa genus, but if i were a betting man, i would think it to be acacia.
the second one looks more like albizia than calliandra to me.
i would really wait for nen888 or some other acacian to ID these, if i were you; but from my guess it looks like the top pic may be a DMT source, and the second one is a good tree to test for content (with a reagent kit or what have you).
