NUTTALL'S ALKALI GRASS

Higher Taxonomy
Family: Poaceae (Gramineae)View DescriptionDichotomous Key

Common Name: GRASS FAMILY
Habit: Annual to woody perennial herb; roots generally fibrous. Stem: generally round, hollow; nodes swollen, solid. Leaf: alternate, 2-ranked, generally linear, parallel-veined; sheath generally open; ligule membranous or hairy, at blade base. Inflorescence: various (of generally many spikelets). Spikelet: glumes generally 2; florets (lemma, palea, flower) 1--many; lemma generally membranous, sometimes glume-like; palea generally +- transparent, +- enclosed by lemma. Flower: generally bisexual, minute; perianth vestigial; stamens generally 3; stigmas generally 2, generally plumose. Fruit: grain, sometimes achene- or utricle-like.
Genera In Family: 650--900 genera; +- 10550 species: worldwide; greatest economic importance of any family (wheat, rice, maize, millet, sorghum, sugar cane, forage crops, ornamental, weeds; thatching, weaving, building materials). Note: Generally wind-pollinated. Achnatherum, Ampelodesmos, Hesperostipa, Nassella, Piptatherum, Piptochaetium, Ptilagrostis moved to Stipa; Elytrigia, Leymus, Pascopyrum, Pseudoroegneria, Taeniatherum to Elymus; Hierochloe to Anthoxanthum; Lolium, Vulpia to Festuca; Lycurus to Muhlenbergia; Monanthochloe to Distichlis; Pleuraphis to Hilaria; Rhynchelytrum to Melinis.

Genus: PuccinelliaView DescriptionDichotomous Key

Common Name: ALKALI GRASS
Habit: Annual, perennial herb; stolons and rhizomes generally 0. Stem: decumbent to erect. Leaf: basal and cauline; sheath open +- to base; ligule thinly membranous, acute to truncate, sometimes toothed. Inflorescence: panicle-like; lower branches reflexed to erect in fruit; spikelets stalked. Spikelet: bisexual; glumes < lowest floret, lower glume generally 1-veined, upper 3-veined; florets 2--9; lemma generally firm, back generally rounded, sometimes weakly keeled near tip, margin entire to scabrous-serrate near tip at 10×, glabrous to +- puberulent at base and along the veins in lower 1/2, generally glabrous elsewhere on surface, generally faintly 5-veined; awn 0; palea +- = lemma.
Species In Genus: +- 120 species: temperate to arctic, North America, Eurasia, southern hemisphere. Etymology: (B. Puccinelli, botanist, Italy, 1808--1850) Note: Generally on wet saline or alkaline soils in coastal and inland habitats; some species difficult to separate without hand lens.
