Classifying a Plant Sample by Vascular, Seed, and Flower Criteria

The idea
This procedure sorts an unfamiliar plant sample into bryophyte, seedless vascular plant, gymnosperm, or angiosperm groups by applying three criteria in sequence.
Where people slip
Checking seed enclosure before confirming a seed is present at all inverts the correct order — a seedless vascular plant has no seed to check for enclosure in the first place.
