Brachypodium sylvaticum

Higher Taxonomy
Family: Poaceae (Gramineae)View DescriptionDichotomous Key
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: BrachypodiumView DescriptionDichotomous Key

Common Name: FALSE BROME
Habit: Annual, perennial herb from rhizomes or cespitose, 5--200 cm. Stem: decumbent to erect; nodes often hairy. Leaf: generally cauline; blade flat to inrolled, glabrous to short-hairy; ligule membranous. Inflorescence: spike- to raceme-like; spikelets generally 1 per node, +- cylindric, ascending to appressed, sessile to short-stalked. Spikelet: glumes unequal, <= lowest floret, 3--9-veined, acute to awned; florets 3--24, bisexual; axis breaking above glumes and between florets; lemma back rounded, 5--9-veined, acute to awned from tip; palea slightly < lemma, clearly ciliate or toothed.
Species In Genus: +- 18 species: temperate, subtropics worldwide. Etymology: (Greek: short foot, from short, thick spikelet stalk in some species) Note: Reports of Brachypodium phoenicoides (L.) Roem. & Schult. from Sonoma Co. have not been verified.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
