WEEPING LOVE 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.

Common Name: LOVE GRASS
Habit: Annual, perennial herb; often glandular, glands often wart-like, round, pitted. Leaf: sheath margin hairy on sides just below collar; ligules ciliate. Inflorescence: generally panicle-like, open or dense, occasionally spike-like, often glandular. Spikelet: laterally compressed; glumes +- unequal, acute or acuminate, 1(3)-veined; florets 3--many, axis breaking above glumes and between florets, or persistent, with glumes, lemmas deciduous, paleae remaining attached or not; lemma keeled or rounded, acute or obtuse, 3-veined, veins generally obvious; palea +- = lemma. Fruit: 0.4--2.4 mm, variously-shaped, occasionally longitudinally grooved, generally not noticeably compressed, generally red-brown.

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.
