Rhododendrons, as are many plants, are divided up into
groups which are supposed to be similiar. Azaleas are a subgroup
of rhododendrons. At one time all rhododendrons with five stamens
were included in the "series" azalea. But of course, mankind's
definitions do not always hold up. There are "azaleas" with ten
stamens, and rhododendrons with five stamens. Then there is the
problem of evergreen azaleas, and deciduous azaleas, which do not
intercross, but again, with some exceptions. Best to just say,
"azaleas are a kind of rhododendron but only some rhododendrons
are azaleas" and go on to simpler problems.
