Vegetative Morphology | |
| Plants | annual or perennial; cespitose. |
|---|
| Culms | 5-100 cm, mostly erect, unbranched. |
|---|
| Internodes | hollow. |
|---|
| Nodes | glabrous. |
|---|
| Sheaths | sometimes less than 1/2 as long as the internodes, open. |
|---|
| Auricles | absent. |
|---|
| Ligules | hyaline. |
|---|
| Blades | flat, mostly erect. |
Reproductive Morphology | |
| Inflorescences | open panicles. |
|---|
| Branches | sparsely strigose, capillary, spikelets usually pendulous. |
|---|
| Spikelets | pedicellate, oval to triangular in side view, becoming light brown at maturity, laterally compressed but the glumes and lemmas with broadly rounded backs. |
|---|
| Glumes and florets | strongly divergent from the rachillas. |
|---|
| Florets | 4-12(15), chartaceous, distal florets rudimentary. |
|---|
| Rachillas | glabrous, not prolonged beyond the distal rudiment. |
|---|
| Disarticulation | above the glumes and between the florets. |
|---|
| Glumes | subequal, naviculate, faintly 3-7-veined, margins more or less membranous, apices obtuse. |
|---|
| Calluses | short, glabrous. |
|---|
| Lemmas | about as wide as long, similar in shape to the glumes but somewhat cordate, margins becoming hyaline, frequently splitting perpendicular to the midveins, unawned. |
|---|
| Paleas | shorter than the lemmas, scarious or chartaceous. |
|---|
| Lodicules | 2, joined or free, usually entire, sometimes toothed. |
|---|
| Anthers | 3. |
|---|
| Ovaries | glabrous. |
|---|
| Caryopses | ovoid to obovoid, hila round to elliptic. |
|---|
Species Distribution Maps
Chromosome Number(s)x = 5, 7 Additional NotesFrom the Greek brizo, 'to nod', in reference to the spikelets. Briza, a genus of about 20 species, is native to Eurasia and South America. Most species have little to no fodder value because of the scant foliage. The ornamental value of the genus is more significant; they are often grown for use in dried floral arrangements. Three European species are now scattered in the more temperate parts of southern Canada and the United States, and will undoubtedly be collected in areas not indicated here. Briza species can become weedy where established.
