Eldred –
The indenting is very good, and the descriptors are good, in that most of them are describing a single characteristic or its opposite.
That said, please help me out. What do you mean by “yellow tips”? So much of your key relies on knowing what they are.
Also, Plant 4 definitely has leaves. Fuzzy leaves, at that. They are very visible in one of those photos.
Couplet C is off in another way: you should use the same characteristic to differentiate the couplet (“Leaves are fuzzy” would lead to “Leaves lack fuzz”, and you can see from what I wrote above that fuzz is not a characteristic you can successfully employ when resolving to Plant 4).
Please try again. I believe you can edit what you have above, and it would be worth it.

Hi Steph, thanks for the feedback I have made some revisions.

Hi Eldred –
Don’t worry about the indenting. I remember your original submission, and it was right. WordPress is being… persnickety.
Thank you for clarifying about the anthers. That one might be a little tricky to use, since anthers tend to spread out at maturity. I think what you’re meaning is that one is a bit more internally set (your “packed closely”), while the other two flowers, the anthers are a bit more external and have room to spread out (“spread apart”). If you want to consider editing, there’s another, general, characteristic relating to the anthers that’s more compelling, that would follow your same key. You don’t need to make this change – but you can, if you see it.
Couplet C is still off. Plant 3 and Plant 4 both have fuzzy leaves. There’s a MUCH more obvious difference between these two flowers, however. Maybe take a peek at your classmates’ submissions…
Thank you for editing!
Steph
