|discussion=<p><i>Euphorbia missurica</i> is similar to the western <i>E. parryi</i> but has a more upright growth habit and more conspicuous involucral gland appendages. Native occurrences have been documented from Minnesota (last collected in Ottertail County in 1936), but it appears to have been extirpated from that state due to habitat loss to agriculture.</p>
