Ecology & Life History

General Description: Pale Sedge occurs in small clumps arising from long, slender rhizomes, and has flowering stems up to 20 cm tall. Leaves are clustered on the lower third of the stem and have a thin pale-bluish waxy coating; they are 1-4 mm wide with long, pointed tips. The inflorescence consists of 2-3, or sometimes 4, loosely clustered spikes. The narrow terminal spike is 7-30 mm long and either is composed entirely of male flowers or has several fruits borne at the top. The lower spikes are composed entirely of female flowers and are borne on short stalks; the uppermost leaf (bract) just below the lowest spike usually exceeds the uppermost spike. Scales that make up the spikes are light or dark brown in color with a green midvein. The perigynia are 2-4 mm long, pale green and glabrous, and elliptic or ovate in outline with a short beak at the tip; the enclosed seed is triangular in cross-section.
Technical Description: From CNHP Wetland Guide 2012: Habit: stems arising singly or few together from slender, long, creeping rhizomes. Culms: slender, erect, triangular, 0.5-6 dm tall, longer or shorter than the leaves, phyllopodic, basal leaves persistent. Leaves: 6-12 Blades: firm, narrow, often channeled, glaucous, 0.5-3.5 mm wide. Sheaths: smooth, thin, membranous, concave at mouth. Spikes: 2-4, green to yellow green, sessile or short-pedunculate. Terminal spike staminate, erect, linear, 0.7-3 cm long, 3-4 mm wide. Lateral spike is pistillate, narrowly oblong, slender, loosely flowered, 1-2.5 cm long, 5 mm wide, approximate to somewhat remote, perigynia appressed. Pistillate Scales: ovate, obtuse to somewhat acute or mucronate at tip, equaling or shorter and narrower than perigynia but partially enveloping the perigynia bases, center is broad and pale green with white or brown hyaline-scarious margins. Perigynia: narrowly rhombic or elliptic, obtusely trigonous with a broadly short-stipitate base when dry, broadly tapered at the apex, leathery, puncticulate or papillate, glaucous green, 2.2-4.5 mm long, 1.2-2.4 mm wide. Nerves: lacking, marginally ribbed. Beaks: absent or up to 0.2 mm long, orifice darkly rimmed. Stigmas: 3

Diagnostic Characteristics: In its bog habitat, Carex livida is best distinguished by its relatively short stature and glaucous foliage.

From CNHP Wetland Guide 2012: Main Characteristics:
Strongly rhizomatous with glaucous foliage
Beakless, light green perigynia contrasts with dark brown scales
Pistillate scales ovate, obtuse to somewhat acute or mucronate at tip, equaling or shorter and narrower than perigynia, center is broad and pale green with white or brown hyaline-scarious margins


Habitat Comments: Peat bogs and swampy woods (Idaho Native Plant Society, 1992).
