I'm not going to make work for Alan as I know he has enough on his plate.
Believe it or not, I like to be made aware of missing words, especially ones that I've heard of. It may result in additions to the word list that will increase people's enjoyment of the puzzle.
As Mike has pointed out,
Alsatian is generally written with a capital
A. But this is not always the case, so I'll have a look at it in due course.
Grevillea is also often written with a capital letter, perhaps because it is a genus name. But it is also used without capitalisation as the common names of various species. However these species are all native to Australia and nearby places, so may not be mentioned in some northern hemisphere dictionaries. I'll have a look at this one too.
