Carex helleri (Heller's sedge) is a native California grass in the Cyperaceae family, recognized by . Key features are high elevation habitat, reddish-purple seed cases, and awned pistillate bracts.
Heller's sedge is a California native perennial sedge found in the Sierra Nevada Mountains, Sierra Nevada Eastern edge, and White and Inyo Mountains in dry, rocky or gravelly slopes at elevations of 2,400 to 4,100 meters. Growing in dense tufts with stems 5 to 40 centimeters tall, this sedge develops narrow leaf blades 2 to 3.5 millimeters wide. Its inflorescence forms a compact, head-like cluster with terminal spikelets that are predominantly pistillate, featuring reddish-brown to purple bracts with acuminate tips. The plant produces distinctive fruits approximately 1.4 to 1.8 millimeters long, characterized by elliptic to obovate perigynia that are generally red-brown to purple, with a small beak 0.2 to 0.5 millimeters long. Its tightly clustered growth habit and narrow leaves make this sedge well-adapted to high-elevation, rocky mountain environments.
