Phenology update: curly dock

Curly dock (Rumex crispus) is flowering and fruiting.  You can tell it apart from Broadleaf dock (Rumex obtusifolius) by looking at the calyx on the fruit (wing on the seeds).  Curly dock (seen below) has smooth edges whereas broadleaf dock has small teeth on the calyx.  Follow this link to see pictures http://www.missouriplants.com/Greenalt/Rumex_obtusifolius_page.html
