Lactuca floridana, the woodland lettuce,[2] is a North American species of wild lettuce. It is widespread across much of central Canada and the eastern and central United States from Ontario and Manitoba south as far as Texas, Louisiana, and Florida.[3]

Lactuca floridana is an annual biennial herb in the dandelion tribe within the daisy family growing from a taproot a height of up to 200 cm (79 in; 6.6 ft). The top of the stem bears a multibranched inflorescence with many flower heads. Each head contains 10–20 blue or white ray florets but no disc florets. The fruit is a brown achene.[4]

Lactuca floridana was found to contain 11β,13-Dihydro-lactucin-8-O-acetate hemihydrate.[5]
