Melaleuca scabra is one of a number of strongly allied poorly known species which was introduced into England in 1803. It is now known to be restricted to a region in the Hopetoun – Israelite Bay district of Western Australia.

What really amazes me about this one is the light UV-reflective parts of the flower. They were always black in Eucalyptus and Acacia so I'm trying to get my head around that! This is the time of year for these flowers so I'm doing as many as I can find.

Cheers,

Dave

The difference in this specimen in the UV compared to the others you have photographed makes me wonder if this one might at some time be reclassified? Such reclassification not based on the UV appearance per se, but that the UV appearance indicates some underlying biological difference from the other Melaleuca.

Although, the M. wilsonii is also UV-brighter than the others.

Funny you should say that. Some authors think that Melaleuca is very broad and should also include Calistemon which I'm about to post.
