Other info. - This is one of the easiest plants to ID in the field because of its very large basal leaves. The leaves appear very early in the season and begin to dry at anthesis. The flowering stem bolts very rapidly and can reach full height in just a few days. This species is very common in the state.
Steyermark lists four varieties for the species, three of which are based on leaf scrabrescence. These 3 varieties are no longer used.
