[In Kirschner's (2002c) key to Section Tenageia of Juncus, he differentiates J. bufonius from J. ranarius on capsule and tepal traits. In J. bufonius, the apex of the capsules is acute to obtuse and equal to or shorter than the inner tepals, which are acute to subobtuse, while in J. ranarius, the capsules are more truncate and usually exceed the inner, obtuse tepals. J. bufonius is typical of fresh water habitats, while J. ranarius is usually found in brackish or saline habitats.]
