Key characteristics

This species is related to T. barbinode from which it differs in having hairy bleaf blades (vs hairless), leaf sheaths shorther than the nodes (vs. longer), glumes shorter than the florets (vs. equaling or longer than the spikelet). Its distribution is in the Central Valley and on the coast in Central Chile at low elevations (vs, the Andes above 1000 m above sea level).
