Your A couplet is a little off. Each branch should have a single description. It’s best if one branch describes a feature – e.g., has cones or has needles (which is a kind of leaf, btw, so be careful of phrasing) – while the other branch describes the lack of that same feature – e.g., lacks cones (or lacks needles). Your B couplet is a PERFECT example for this. And because your C couplet resolves both branches, saying one plant has purple petals while the other plant has white petals is very appropriate (no need for “lacks” here).
Also for the A couplet: Plant 4 isn’t herbaceous – it’s a tree. Plants 2 and 3 are herbaceous. What Plants 2, 3 and 4 lack, of course, is cones (or needles, but cones is more obvious).
Great job! Thanks for resubmitting!

Hey Andrew! I can read your key, but the ‘A’ rows are a little confusing. Maybe “Broad Leaves” vs. “Needles” would be more suitable?

With my limited knowledge of plants, this key worked for me as it allowed me to connect the necessary dots to figure out what is what. Nice job!

Hey Andrew, another way to phrase your A couplet would be by its seed type. Gymnosperm or Angiosperm. Great job and easy to follow though!
