Puccinellia lucida is a perennial grass which grows in south-eastern Canada and occasionally elsewhere in the United States. Its specific epithet lucida means "shining", referring to the plant's lustrous glumes.
Puccinellia lucida is a green, loosely cespitose grass growing 15–70 cm (5.9–27.6 in) tall. It has cauline leaves with flaccid, involute blades. Its basal leaf sheaths can be somewhat purple. Its acute ligule is 1.7–2.5 mm (0.067–0.098 in) long. Its diffuse panicle is 10–25 cm (3.9–9.8 in) long, with filiform, scabrous floral branches. Its pale green spikelets are 5–9 mm (0.20–0.35 in) long and bear three to five flowers. Its glumes are thin and lustrous; the first glume is 2–3.5 mm (0.079–0.138 in) long, hyaline above, and minutely serrulate, and its second glume is 2.5–4 mm (0.098–0.157 in) long. Its lemmas are 3–4 mm (0.12–0.16 in) long, broadly ovate, acute, and are pubescent especially towards their base where hairs become longer. The grass flowers from July into August. [1]
Puccinellia lucida is most similar to the species Puccinellia laurentiana , Puccinellia airoides , and Puccinellia macra . From the first two species P. lucida differs in its longer, thinner, and lustrous lemmas; from the first additionally by its scabrous floral branches and softer, greener foliage, and from the second by its longer grain and less exerted panicle. From the third species P. lucida differs in its involute leaves, diffuse panicle, pale spikelets, and longer lemmas. [2]
Puccinellia lucida occurs in saline marches and coastal sands along the lower St. Lawrence River in Quebec, but rare populations have also been found in Wyoming to British Columbia and into California. [1]
Bromus catharticus is a species of brome grass known by the common names rescuegrass, grazing brome, prairie grass, and Schrader's bromegrass. The specific epithet catharticus is Latin, meaning cathartic. The common name rescuegrass refers to the ability of the grass to provide forage after harsh droughts or severe winters. The grass has a diploid number of 42.
Bromus ciliatus is a species of brome grass known by the common name fringed brome. It is native to most of North America, including most of Canada, most of the United States except for some portions of the South, and northern Mexico. It is a plant of many habitats, including temperate coniferous forest. The specific epithet ciliatus is Latin for "ciliate", referring to the delicate hairs of the leaf blades.
