In Montana, the diversity and abundance of all warm season grasses, including the species belonging to these two tribes, are expected mostly along roadsides and similarly disturbed settings (e.g., lawns, pastures, gardens) and where the growing season is the longest, such as at lower elevations of eastern Montana. These species are common in tall- and mixed-grass prairies of the Great Plains but Montana lacks such vegetation.
Tribe Andropogoneae95. Andropogon gerardii.
96. Andropogon hallii.
97. Andropogon scoparius.
98. Andropogon ischaemum (permanent mount). This species has yet to be included in the Montana Grasses app. An introduced perennial bunchgrass, often known as Bothriochloa ischaemum, common along roadsides and in pastures in the southern USA and northern Mexico and known in Montana from a roadside near Polson (Lake County). Similar to big bluestem but much more slender.
99. Sorghum halepense.
100. Sorghum bicolor (permanent mount).
101. Sorghastrum nutans.
102. Zea mays (permanent mount).
103. Tripsacum dactyloides (not known from Montana and thus not in Lesica or the Montana Grasses app).
Tribe Paniceae15. Panicum capillare (from the first lab).
104. Panicum miliaceum.
105. Panicum virgatum.
106. Dichanthelium acuminatum.
107. Digitaria sanguinalis.
108. Echinochloa crusgalli.
109. Setaria viridis.
110. Setaria pumila.
111. Setaria verticillata (permanent mount).
112. Cenchrus longispinus (permanent mount).
Other Paniceae species you should be aware of because they include turf, crop, or ornamental cultivars.Paspalum dilatatum.
Stenotaphrum secundatum. St. Augustine grass. An introduced stoloniferous perennial grass commonly used as a turf grass in the southern latitudes of the USA and elsewhere. The panicoid spikelets occur on one side of a thickened inflorescence rachis in a secund arrangement.
