'''''Allolepis''''' is a genus of North American plants in the grass family.<ref>Soderstrom, Thomas Robert & Decker, Henry Fleming 1965. ''Allolepis:'' a new segregate of ''Distichlis'' (Gramineae).

''Allolepis texana'' is similar to ''Distichlis'' spp. It is a dioecious, perennial herb reproducing by means of stolons running along the surface of the ground. Stems are glabrous, up to {{convert|70|cm|in|abbr=on}} tall. Leaf blades are flat or somewhat folded, up to {{convert|43|cm|in|abbr=on}} long and {{convert|6|mm|in|abbr=on|frac=4}} wide. The inflorescence is a tight panicle up to {{convert|6|cm||abbr=on|frac=2}} long with 5–70 spikelets. Staminate plants have up to 20 flowers per spikelet, pistillate plants only 5–9.<ref>Correll, D. S. & M. C. Johnston. 1970. Manual of the Vascular Plants of Texas i–xv, 1–1881. The University of Texas at Dallas, Richardson.</ref>
All of the known US populations are staminate (male), lacking female flowers, reproducing vegetatively.
== Distribution and habitat == The species is native to western Texas and northern Mexico (Chihuahua, Coahuila, Durango, Tamaulipas).<ref name="s" /><ref>[http://www.theplantlist.org/browse/A/Poaceae/Allolepis/ The Plant List]</ref><ref>Dávila, P., Mejia-Saulés, M.T., Gómez-Sánchez, N., Valdés-Reyna, J., Ortíz, J.J., Morín, C., Castrejón, J. & Ocampo, A.
