|discussion=<p>Although placed by K. K. Mackenzie (1931–1933, parts 2–3, pp. 231–231) in sect. Bicolores Tuckerman, <i>Carex rufina</i> is a member of the C. acuta complex, and appears to be very closely related to <i>C. lenticularis</i>. It differs from <i>C. lenticularis</i> in the red-brown spotted perigynia, black scales, and gynecandrous terminal spike.</p>
