i think we should have 12 trees...

how?

because we will have only two different types of trees of height =1 and 2 (all four trees will be considered as same if we put the values of a,b,c means they will be isomorphic)respectively...

and we can arrange them in 3! ways

so total ways = 2*3! = 12...

//this is my approach...
