Pretty sure on ID but very open to correction. Spikelets one per node, range off and habitat completely wrong for E. lanceolatus, don't think it's E. repens due to cespitose habit and lack of rhizomes (see last two photos). Habitat correct for E. trachycaulus. Open glumes remaining on old plants are apparently typical for this species.

Some of the 500+ Ambyostoma laterale captured from a roadside then later realeased. This was for an IACUC-approved mortality study, so we didn't just put these salamanders in a bucket for no good reason
