It's a Melastomataceae.

Hi,

Most probably this is Melastoma malabathricum, which is a common and widespread pioneer species in SE Asia and Malesia. There exist other species of this genus, but probably none of them occurs in the area near Krakatau. A revision of the genus was published in 2001: http://dare.uva.nl/cgi/arno/show.cgi?fid=565341

OK, there is also Melastoma setigerum and M. velutinosum in western Java, i.e. close to Krakatau. However, these should have smaller flowers.

Are you sure, that the trees in the background of the photo are Cupressaceae, and not Casuarina equisetifolia?

Yes, I agree with Franz with Melastoma, but about the species it needs some more close up photographs. There are one genus in our country (Bangladesh)like  the Melastoma, it is known as Osbeckia. You may check this one also!!

Species Name : Melastoma malabathricum.

Family: Melastomataceae

Thanks, is it usual for such biotopes?

I"m putting some more photos. It was extremely bad Internet in Jakarta. Couldn't put before.

Surely it is Melastoma malabathricum L. (Syn. Melastoma affine D. Don) of family Melastomataceae.

Typical for such biotopes?

Yes it is typical for such biotopes.

Thanks Arvind.

Last two pictures confirmed it as Melastoma malabathricum.
