Lactuca & Prenanthes (Wild lettuces) Identification

Описание к видео Lactuca & Prenanthes (Wild lettuces) Identification

Led by Dr. Tom Rosburg.
Lactuca (wild lettuce) and Prenanthes (rattlesnake root) are two of the more common genera in the Tribe Cichorieae, Family Asteraceae. The Tribe is distinguished by its ligulate heads and usually milky sap. Similarity in size and leaf morphology creates a resemblance between Lactuca and Prenanthes. This session discusses identification of the 10 species in Iowa that comprise this group.
