Taxonomy

Kingdom: Plantae

Subkingdom (unranked): Tracheobionta

Superdivision (unranked): Spermatophyta

Division: Magnoliophyta

Class: Liliopsida

Subclass (unranked): Commelinidae

Order: Cyperales

Family: Cyperaceae

Genus: Carex L.

Species: C. inops L.H. Bailey

Description

Long-stolon sedge is a loosely caespitose, perennial graminoid. It is low to medium statured compared to other Carex. Culms are 4 to 20 inches (10-50 cm) long. Leaves are slender, stiff, and wiry. Old, dead leaves are persistent, often forming fibrous tufts at the stem base. Inflorescences are terminal staminate and pistillate spikes. Male spikes may be pediceled above female spikes. The fruit is a hairy achene ranging from 1.6 to 2.5 mm long. Seedheads bear 5 to 15 fruits each.

Bloom Period

Distribution

Found in the northwestern Great Plains of the United States and Canada, ranging from the western Dakotas to Montana and Saskatchewan.

Habitat

Stands are found on gently rolling uplands with little to moderate slope.

Uses

Wildlife: Rodents, lagomorphs, and ungulates graze sun sedge. On the Pawnee National Grassland, Ord's kangaroo rats, northern grasshopper mice, thirteen-lined ground squirrels, and deer mice utilization of sun sedge ranged from 0.1% to 5.0% across 1 year. Seasonal utilization was not given. Sun sedge was an important component of the spring and early summer diets of black-tailed jackrabbits on the Pawnee National Grassland. In Wind Cave National Park, elk use of sun sedge was similar from winter to summer (3.7-5.0%) and least in fall (0.9%). Sun sedge was a minor component of the pronghorn diet on the Pawnee National Grassland. Use peaked at 4% in April and May, with only trace amounts consumed in other months. Sun sedge was also a minor component in the pronghorn diet (17% frequency but 1%-4% utilization) in a needle-and-thread grass-western wheatgrass community in southeastern Alberta. On the Pawnee National Grasslands, bison grazed sun sedge in trace amounts in December and did not utilize it in other months.

First Nations: Used by Navajo as a gastrointestinal aid and to help fight infections.

Seed

Abbreviation: CAIN

Seed sample from: 2010

Average measurement: 3.6 x1.6 x 1.3

Measurement Range: L: 2.5 – 4.5, W: 1.2 – 2, D: 1 – 1.9

Features

Shape: Seeds narrow at hilum and opposite apex, rounded in middle. Opposite apex usually sharply pointed. Seed sometimes has bits of husk still attached. Hilum circular.

Color: Tan with some darker brown or black spotting. Hilum usually brown.

Surface: Some concave patches, entire seed covered in fine hair, and matte.

Latitudinal Cross Section: elliptical CAIN lat.png

Longitudinal Cross Section: elliptical CAIN long.png

Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
