Ecology & Life History

Basic Description: A loosely tufted to stoloniferous perennial sedge with long, slender rootstock. Fertile culms up to 3 dm tall.
General Description: Carex garberi is a tufted grass-like perennial. Its leaves are 1.0-3.5 mm wide. Arising from the bases of the plants are stems 5-40 cm tall. These main stems are terminated by a cluster of flowers/fruits. The upper flowers are female and the lower are male. Female flowers / fruits also occur at the tips of secondary stems which attach to the main stems. Mature fruits are white and 2-3 mm long (Ball 2002).
Technical Description: Culms stiffly erect 0.5-4 dm high, leaves stiff, flat, erect, 1.5-5 mm broad, shorter than to overtopping the culms. Spikes 3-7, the terminal spike linear, entirely staminate or pistillate usually 10-15 mm, subtended by bracts with short sheaths. Lateral spikes pistillate, 10-15 mm long. Pistillate scales round ovate, appressed to the perigynia, shorter than the perigynia, with brown sides and a conspicuous green midvein, very blunt. Perigynia in overlapping rows, somewhat flattened, elliptic in cross section, 2-3 mm long, membranous, prominently ribbed at maturity, minutely granular- pulverulent.
Diagnostic Characteristics: Spikes two or more to a culm. Uppermost and lowermost spikes distinctly unalike. Lower pistillate spikes erect or strongly ascending, sessile or short peduncled. Mature perigynia membranous, whitish pulverulent; pistillate scales blunt or rounded. Perigynia turgid, obovoid, elliptic in cross section. Achenes lenticular to plano-convex; stigmas two or more per culm.
Duration: PERENNIAL, DECIDUOUS
Lacustrine Habitat(s): Shallow water
Palustrine Habitat(s): TEMPORARY POOL
Terrestrial Habitat(s): Bare rock/talus/scree, Sand/dune
Habitat Comments: Wet open situations on calcareous or sandy substrates; limestone exposures, quarries, seepages, beach pools, and interdunal swales.
