Voucher #14935


Identification (Voucher 59144)

Family
Poaceae
Genus
Avena
Date determined
Identification comments
Jepson eflora measurements seem inconsistent with either sterilis or fatua (e.g., lemma tips too long for fatua, leaf blades too wide for sterilis, and glabrous). Went back later and the spikelets were disarticulating, so presumably not A.sterilis as I was first suspecting.
