We have various colors of Syzygium malaccense: greenish, white, white
and pink, red striped white, reddish, blackish. The most important
characters for S. malaccense are:
1. Stem monopodial,
2. Canopy usually conical
3. Bark whitish to yellowish brown
4. Inflorescence pink, deep pink, to crimson
To me the picture in the link is very close to a white cultivar of S.
samarangense, if the inflorescence is white.
