I don't think it's ssp.
malaccensis - your pups are showing none of the characteristic red blotching nor do they have the bluish sheen produced by the presence of wax.
Tog's photos give a good idea of the ssp.
malaccensis, especially as young plants.

I'd be leaning towards ssp-
acuminata, myself - the only blotched trunk rules out ssp.
truncata (which has a black pstem), and ssp
acuminata tends to be glaucous due to the presence of wax, as is showing well on your pups.
