Morphology of Leptochloa fascicularls (Lam.) Gray (Poaceae) was studied in 25 locations in eastern and central Nebraska to determine if this grass was separable into two distinct taxa as suggested in several recent sources. Field collections were supplemented with herbarium samples from the University of Kansas. Glume and lemma lengths, the characters used in published keys, provided no separations useful in dividing the material into two species or varieties. However, individual local populations exhibited significant differences from each other in these characters. Such local differences appear to be reasonable given the high degree of inbreeding that is to be expected with cleistogamous reproduction such as that predominating at most of the more xeric field locations. Chasmogamy was confined to moist habitats.
