Calamagrostis stricta (Timm) Koel. ssp. stricta
Neglected Reed Grass
Habitat: Swales and shores, usually circumneutral. [Non-tidal rivershore (non-forested, seasonally wet)]
Range: Circumboreal, south to Newfoundland, northern Maine, Michigan, Wisconsin, Colorado, and California.
Aids to Identification: Identification of species of the genus Calamagrostis is usually difficult and dependent upon rather technical characters. They are all perennial grasses with long, narrow leaves, and 1-flowered spikelets with a tuft of hairs at the base of the lemma.
This particular species is very similar to New England northern reed-grass (C. stricta ssp. inexpansa). Both species grow to 30-100 cm in height, with spike-like flower clusters, and spikelets 3-5 mm long. Subspecies stricta is characterized by smooth leaves, and ligules 1-3 mm long with an entire apex.
Ecological characteristics: In Maine this species is known to occur on sparsely vegetated, rocky shorelines, as well as open ledges and outcrops in alpine settings.
Phenology: Fruits late June - August
Synonyms: Arundo neglecta Ehrh.; Calamagrostis neglecta (Ehrh.) P.G. Gaertn. et al. ssp. stricta (Timm) Tzvelev; Deyeuxia neglecta (Ehrh.) Kunth. Subspecies not delimited by Gleason and Cronquist (Second ed., 1991).
Known Distribution in Maine: This rare plant has been documented from a total of 7 town(s) in the following county(ies): Aroostook, Franklin, Piscataquis.
Reason(s) for rarity: At southern limit of range, and habitat naturally rare.
Conservation considerations: Populations along rivershores could be harmed if all-terrain vehicle use increases.
