Two clavicipitaceous fungi infecting grasses illustrate the case where each host genotype is infected with a single pathogen genotype, Balansia obtecta infecting sandbur
grass (Cenchrus echinatus) and Atkinsonella hypoxylon infecting Danthonia spicata (Diehl 1950).
tripsacoides, Cenchrus spinifex coastal sandbur
In many parts of the far Midwest the sandbur
creates a vicious obstacle course, along with another bad vegetative citizen, the goathead bur.
sexlineatus are sand-loving species, the former is mostly limited to alluvial deposits (Walker 1987a) whereas the latter is mostly limited to broadly distributed eolian deposits where species of the lizard genus Holbrookia and the sandbur
genus Cenchrus are ecological indicators (Paulissen et al.
Depending on the site, species interspersed with little bluestem included dewberry (Rubus riograndis), sandbur
Highway 281 (Brooks County): sandy roadside with clumps of sandbur
, patches of dense grass along a fence row, and mesquite trees in the center of the highway island at the junction of U.
Major subdominants include silver bluestem (Bothriochloa saccharoides), big bluestem (Andropogon gerardii), plains bristlegrass (Setaria leucopila), sideoats grama (Bouteloua curtipendula), Texas wintergrass (Stipa leucotricha), buffalograss (Buchloe dactyloides), hairy grama (Bouteloua hirsuta), knotroot bristlegrass (Setaria geniculata), indiangrass (Sorhastrum nutans), eastern gamagrass (Tripsacum dactyloides), and big sandbur
