In short:
Spotted (Maculata) - Flat-headed pannicles of flowers, purple spotted stems (sometimes purple spots on purple stems which can be hard to see). Stems may be hollow, especially at the base. Stems are said to be pubescent. This is usually shorter with no more than 6 leaves per whorl. Petioles are short, teeth on leaves are sharp.
Hollow (Fistulosum) - Mounded pannicles of flowers, 5-7 florets per head. Greater number of leaves per whorl (4-7), hollow stem, Glaucus (strong bloom on central stem).
Sweet (purpureum) - Mounded pannicles of flowers, no more than 5 leaves per whorl, glabrous stems, stems green although they may be purple at nodes. Stems are solid. Likes a drier habitat than others.
Coastal plain Joe-pye - leaves strongly three nerved. Occurs farther inland from the coastal plain, so location to identify must be used cautiously. Inflorescence rounded or strongly convex. Stems entirely purple.
