Is it me or is there a mistake in this weeks garden news crossword.
I have completed all but 9 across which is left
g-i-e-s
clue
"Species name meaning grey.

We also have "acer griseum". Are you sure the last letter is s?

No reason why it shouldn't be. Botanical Latin makes some attempt to
follow latin grammar. All nouns in Latin are one of three genders, male,
female or neuter, and the adjective has to match the ending. So a neuter
Acer is griseum where as a masculine Ceonothus is griseus and a feminine
Avena sativa variety is grisea.
