Lactuca ludoviciana
(Louisiana Lettuce)


Family: Asteraceae

Status: Native

Synonyms:
Sonchus ludovicianus Nuttall

Lactuca ludoviciana, Lactuca graminifolia & Lactuca pulchella are all very similar. All have bluish, yellow, white or purple flowers with leaves that can be linear or linear lanceolate, and beaked achenes. The distinguishing character for Lactuca ludoviciana is that the entire stem is leafy rather than just the bottom 1/2-3/4 of the stem. Lactuca ludoviciana is found in the western portion of the Gila National Forest at middle elevation in the Ponderosa Pine forest.
