Very similar to Bothriochloa laguroides ssp. torreyana which some workers consider to be the same species. Gould (1978) distinguishes between these two species by their glumes which are narrowly ovate and shiny green in var. longipaniculata and ovate, broad and blunt, and dull green in var. torreyana. He also sites the presence of a white waxy covering of the inflorescence and vegetative parts in torreyana (not always present). The inflorescence of var. longianiculata is usually longer than 10 cm while those of B. laguroides var. torreyana are usually shorter than 10 cm long. The ligule of B. longipaniculata is membranous and 2-3 mm long while the ligule of B. laguroides var. torreyana is only 1-2 cm long.
Seeds collected from remnant populations average approximately 300,000/lb.
Good for livestock forage but does not persist in overgrazed pastures. Provides nesting cover for birds, escape cover for rodents and rabbits, foraging habitats for raptors and canids, and fawning cover for deer.
Restricted in range to Louisiana, Texas and Mississippi.
Along roadsides and fields, open woodlands, disturbed ground, and swales of the Gulf coastal prairie. Often found in heavy clay soil.
