Carex × wolteri differs from C. vesicaria by its longer female spikes, aristate and ciliate male and female glumes, shorter utricles with a deeply bifid beak. From C. pseudocyperus it can be distinguished by its shorter lowest bracts (in the hybrid, the bracts are as long as or slightly longer than the inflorescence) and shorter, usually sessile 1 or 2 female spikes. The empty utricles are usually dull green-brown and glabrous, 4–5 mm long with a 1.5–2 mm long, deeply bifid beak.</p><p>Habitat.</p><p>Wetlands, river valleys, swamp forests.</p><p>Distribution.</p><p>This hybrid is known from Austria, Belarus, Finland, France, Germany, Italy, Norway, Poland, Northwest and Central European Russia, Slovakia, Sweden, and Switzerland (Koopman 2022).</p></div>	https://treatment.plazi.org/id/492B8504E5E95905B49860564A942457	Public Domain	No known copyright restrictions apply.
