Bothriochloa barbinodis
Encyclopedia
Bothriochloa barbinodis is a species of grass
known by the common name cane bluestem. It is native to the Americas, including most of South and Central America, Mexico, and the southernmost continental United States from California
to Florida
.
This is a perennial bunchgrass growing in upright clumps 60 to 120 centimeters tall. The straw-colored stems have nodes at intervals which are fringed with fluffy hairs. The leaves are 20 to 30 centimeters long and blue-green when new, drying to a reddish yellow. The inflorescence
is a feathery array of spikelet units. Each unit is composed of one hairy, tan, fertile spikelet with a twisted awn up to 3.5 centimeters long twinned with a stalked, sterile spikelet which is much smaller and lacks an awn. The long-haired spikelets are wind-dispersed
.
In its native range, this grass is useful as a forage
for grazing animals and a groundcover for revegetating cleared land. It is very drought resistant. It is considered an indicator of rangeland
damage, as it is often one of the first native species to be eliminated when an area is overgrazed
.
It is known elsewhere as an introduced species
and sometimes a weed, such as in Hawaii
.
It is grown as an ornamental plant
for its showy inflorescences.

The Poaceae is a large and nearly ubiquitous family of flowering plants. Members of this family are commonly called grasses, although the term "grass" is also applied to plants that are not in the Poaceae lineage, including the rushes and sedges...

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Strictly, it is the part of the shoot of seed plants where flowers are formed and which is accordingly modified...

Biological dispersal
Biological dispersal refers to species movement away from an existing population or away from the parent organism. Through simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population...

Forage
Forage is plant material eaten by grazing livestock.Historically the term forage has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially...

Rangeland
Rangelands are vast natural landscapes in the form of grasslands, shrublands, woodlands, wetlands, and deserts. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras...

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, or by overpopulations of native or non-native wild animals.Overgrazing reduces the...

Introduced species
An introduced species — or neozoon, alien, exotic, non-indigenous, or non-native species, or simply an introduction, is a species living outside its indigenous or native distributional range, and has arrived in an ecosystem or plant community by human activity, either deliberate or accidental...
