::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...?)
