Acacia ID's and some sort of disease

[MindExpansion]

Ok, there are 3 different acacia's here (2 pics of one, and then one of the other 2)... but I think they might be the same type, I have more pics if there is any need.

Also really interested about what the white stuff on the last one is...at first I thought maybe some sort of pesticide resin but changed my opinion to think it was maybe a fungus or disease of some sort.

Also then there is a wierd little picy of what I thought mighta been a young, having a mental blank, but one of those things that usually grow in trees, stag horn maybe?

Peace,

Mind

Hey ME, to me the first 2 Acacias look very much like Acacia floribunda...should be flowering at this time of the year, pic 3 Acacia longifolia...appears to have longer phyllodes than the acacia in pic 4, and pic 4 Acacia sophorae (Coastal wattle)... bears close resemblance to longifolia and is often considered a subspecies of longifolia however its leaves are shorter and more oval in shape...may help explain why you thought they were the same species... On the other hand it may be the case that pic 4 is of a young longifolia yet to reach a stage of more typical growth. Were pics 3 and 4 taken at different locations?...was pic 4 taken near the coast?

Hope this helps

Pic 4- that branch is covered in a type of scale!! big time!!

Scale is an insect not a disease, they suck nutrients and goodness from plants - ussually will attach themselves to a weak or stressed plant, as healthy plants often fight them off some how, birds eat scale insects sometimes too.

This plant is under a bit of shade? maybe too much water drowning the plant or too heavy soil? Its deffinantly not at its best, thats why the scale attack- Good spotting!
