Pleuraphis muticaBuckley

Hilaria mutica, synonym Pleuraphis mutica, [1] is a species of grass known by the common name tobosa, or tobosa grass. It is native to Northern Mexico, and the Southwestern United States, in Arizona, New Mexico, Oklahoma, and Texas. [2]

Description

Hilaria mutica is perennial grass that is rhizomatous and forms sod. It usually grows 30 to 60 cm (0.98 to 1.97 ft) tall, sometimes reaching up to 90 cm (3.0 ft). The stems have decumbent bases and erect tops.

Most of the stiff, hairless leaves are basal. They are up to 15 cm (5.9 in) long. The bases of the stems come from a thick, woody rootstock and a system of roots that penetrates up to 1.8 m (5.9 ft) deep in the soil.

The inflorescence is a few centimeters long and is white, straw, or purplish. Spikelets are borne in clusters of three. The plant reproduces mainly by spreading by its rhizome, and does not often form viable seeds. [2] The plant is susceptible to ergot. [3]

Distribution

Hilaria mutica is one of the most common species on the semidesert grasslands in the region. It is a climax species on frequently flooded lowlands. It also occurs on upland territory. Habitat types that feature the grass include pinyon-juniper woodland and mesquite, creosote, and grassy shrubsteppe. It does best on land that is flooded for a few days and then dries up. It also grows on drier soils, and it is somewhat drought-tolerant.

It grows on clay with honey mesquite and other species such as burrograss (Scleropogon brevifolius), alkali sacaton (Sporobolus airoides) and sacaton (S. wrightii) and other dropseed grasses (Sporobolus spp.), grama grasses (Bouteloua spp.), muhly grasses (Muhlenbergia spp.), and tarbush (Flourensia cernua).

Uses

Tobosa is an important forage for cattle and horses in the American Southwest. It is productive and palatable until it becomes rough at maturity. It is especially valuable during drought when it persists after other grasses die. It can be cut into hay when still green. In Texas, it yields 1000 pounds per acre, and this can be increased with careful and deliberate management. In areas with adequate precipitation, burning is used to remove litter, which then stimulates the stems to produce more green matter.

The grass can cause ergot poisoning if eaten when infested with the fungus. [2]

Mesquite Several species of leguminous trees

Mesquite is a common name for several plants in the genus Prosopis, which contains over 40 species of small leguminous trees. They are native to dry areas in the Americas. They have extremely long roots to seek water from very far under ground. As a legume, mesquites are one of the few sources of fixed nitrogen in the desert habitat. These trees bloom from spring to summer. They often produce fruits known as "pods". Prosopis spp. are able to grow up to 8 metres (26 ft) tall, depending on site and climate. They are deciduous and depending on location and rainfall can have either deep or shallow roots. Prosopis is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite.

Chihuahuan Desert Desert ecoregion in Mexico and the United States. Largest desert in North America.

The Chihuahuan Desert is a desert and ecoregion designation covering parts of northern Mexico and the southwestern United States. It occupies much of West Texas, the middle and lower Rio Grande Valley, the lower Pecos Valley in New Mexico, and a portion of southeastern Arizona, as well as the central and northern portions of the Mexican Plateau. It is bordered on the west by the Sonoran Desert and the extensive Sierra Madre Occidental range, along with northwestern lowlands of the Sierra Madre Oriental range. On the Mexican side, it covers a large portion of the state of Chihuahua, along with portions of Coahuila, north-eastern Durango, the extreme northern part of Zacatecas, and small western portions of Nuevo León. With an area of about 501,896 km2 (193,783 sq mi), it is the largest desert in North America.

<i>Sporobolus heterolepis</i> Species of flowering plant

Sporobolus heterolepis, commonly known as prairie dropseed, is a species of prairie grass native to the tallgrass and mixed grass prairies of central North America from Texas to southern Canada. It is also found further east, to the Atlantic coast of the United States and Canada, but is much less common beyond the Great Plains and is restricted to specialized habitats. It is found in 27 states and four Canadian provinces.

<i>Sporobolus</i> Genus of grasses

Sporobolus is a nearly cosmopolitan genus of plants in the grass family. The name Sporobolus means "seed-thrower", and is derived from Ancient Greek word σπόρος (spóros), meaning "seed", and the root of βάλλειν (bállein) "to throw", referring to the dispersion of seeds. Members of the genus are usually called dropseeds or sacaton grasses. They are typical prairie and savanna plants, occurring in other types of open habitat in warmer climates. At least one species is threatened with extinction, and another is extinct.
