'Taxonomists can never agree on something and stick with it! They made some really major changes this time. What's the point of changing names on labels since the names are probably going to change again it a few years?
The name changes were really annoying in my first two years of college where I was taking botany courses. The first year we learned the names of some 500 plants, then some of them changed and we were expected to be up to date. And some of the new names were impossible to learn.
Coleus blumei, nice and easy, became the tongue twisting
Solenostemon scutellarioides I wouldn't be surprised if most of what I learned then is now outdated.
