1 Common Name: PORTER S REED GRASS Scientific Name: Calamagrostis porteri A. Gray ssp. porteri Other Commonly Used Names: Porter s reed bent Previously Used Scientific Names: Calamagrostis porteri A. Gray Family: Poaceae/Gramineae (grass)
2 Rarity Ranks: G4T4/S1 State Legal Status: Rare Federal Legal Status: none Federal Wetland Status: none Description: Perennial grass, forming colonies. Stems 2-4 feet ( cm) tall, unbranched, often leaning, usually hairless, with 2-5 swollen leaf nodes. Leaves often spread across the ground, and consist of a flat blade and a split sheath that tightly encircles the stem. Leaf blade usually 6-12 inches (15-30 cm) long and less than ⅓ inch (4-8 mm) wide, light blue-green on the upper surface and darker, shiny green on the lower surface; leaf sheath very hairy at the collar (bend where the sheath joins the blade), otherwise hairless; ligule (tiny flap of tissue at the top of the sheath, center photo) pale tan and ragged. Flower cluster 4-6 inches (10-15 cm) long, erect at the top of the stem, pale green or purplish; plants may not flower every year. Flower (spikelet) about ⅛ - ¼ inch ( mm) long, pale green or tan, enclosed in 4 tiny bracts, with a sharply bent bristle (awn) about ⅛ inch (3-4 mm) long, and a tiny tuft of hairs, half the length of the spikelet, at its base. Fruit a pointed grain less than 1 / 16 inch (1-1.5 mm) long. Similar Species: Bluejoint reed grass (Calamagrostis canadensis) and Nuttall s reed grass (C. cinnoides, synonym: C. coarctata) have hairless collars; both have straight awns, and the tuft of hair at the base of the spikelet is as long as the spikelet; both grow in wet areas. Related Rare Species: Bartley s reed grass (Calamagrostis porteri ssp. insperata) is not known from Georgia but once occurred in several other southern states; it is now very rare. Its leaves are pale blue-green on both surfaces, and the sheaths have hairless collars. Habitat: Dry, rocky, high elevation ridges and mountaintops with white oak, chestnut oak, and hickory. Life History: Porter s reed grass reproduces vegetatively, forming small colonies of plants, and sexually, although flowering plants are uncommon. As with all grasses, its flowers are windpollinated and seeds are probably dispersed by a variety of insects and small mammals. Survey Recommendations: Surveys are best conducted during flowering (July August) and fruiting (July December). Range: Georgia, north to New York, west to Missouri. Threats: Ridgeline and mountaintop developments and other clearing and soil disturbance; fire suppression.
3 Georgia Conservation Status: Five small populations are known, all on the Chattahoochee National Forest. Because grasses are often overlooked, this species may be somewhat more common than current surveys indicate. Conservation and Management Recommendations: Avoid logging and other mechanical clearing on ridges and summits. Protect mountain tops and ridgelines from off-road-vehicle traffic. Apply prescribed fire occasionally to dry woods. Selected References: Chafin, L.G Field guide to the rare plants of Georgia. State Botanical Garden of Georgia and University of Georgia Press, Athens.
