Marshes, swales, and ditches; swamps, potholes in forests; shores and borders of rivers, ponds, and lakes; often in shallow water (even to 6 dm deep).
The lower leaves if they are (or have been) submersed may be slightly to very extensively dissected, quite unlike the usual leaves, and the submersed stem may be very much inflated. The stem is corrugated, though not so deeply furrowed, as in Pastinaca. The styles are at least 0.5 mm long beyond the stylopodium, and strongly recurved. An occasional plant of Cicuta bulbifera might key here, but the slender leaflets are very deeply toothed, the styles very short, and the stem terete (though striate), apart from the usual presence of bulblets in the inflorescence.
