Aster ageratoides var. ovatus fo. yez. : why 4-part name?
when I came across this Aster, I couldnt really figure out its name. I had some botany lessons and I know the part "var. ovatus" means something like: variety, oval shaped or something.
But the fo. yez. throws me. What is it within the system of naming plants
genus species variety ???
and what does it mean?
The aster is native in/to Asia (sorry dont know more exactly) as far as I know.
Hope you can help, thanks very much, cheers, Lin
