Melaleuca - 'Snow in Summer'
Tree to 10m- white flowers in fluffy spike.
Melaleucas (paperbark or tea-trees) give me a bad time. I found some species very similar, so difficult to ID, and a lot of confusion in Web and with common names.
These small tree is Melaleuca linariifolia as I think. (Though the flowering period is not fully match)
It has a similar flower structure like M. alternifolia (famous one as the source of tea-tree oil ). However, as an expert told me, M. alternifolia has narrower leaves that are mostly alternate, whereas leaves of M. linariifolia are mostly opposite-paired, as I can see on this tree. Also I think M. alternifolia is smaller - up to 3m only.
Sorry, I had to use flash for this shot, as it was late evening.
