I think the reason I spotted the errors was simply due to my ignorance of the subject matter meaning I had to read it carefully to try and understand what it was saying It s obviously a very easy name to slip up on in the previous section about flower colour both yourself and used non scriptus instead of non scripta and I was going to do likewise until not wanting to appear as the botanical ignoramus I thought I d better check the name to be doubly sure As regards the first sentence I prefer your proposed alternative as it does make it clearer but I wonder if in addition it would be possible to make a brief explanation somewhere as to why non scriptus should change to non scripta when applied to a different genus name or would that be getting too bogged down in nomenclatural particularities I m assuming the change is something to do with the laws of Latin with respect to gender although I can t see why different genera should have different genders
