It really is best to try to remember the latin. It's the one name that
will identify the plant without ambiguity,

Are not the so called experts reclassifying plants and their outdated
Latin names?

The latin name reflects the hierarchy of the evolution of plants. As we
learn more about the evolution, it is seen that some plants were wrongly
considered to have descended from one branch rather than another. So the
latin name has to be changed to reflect the new knowledge.

Of course, in this age when 'celebrity' is the thing (or being famous
for being famous), knowledge and expertise increasingly becomes the
subject of scorn.
