This, like L. undulata, is senecionoid in habit and very variable. Stem 3-18 in. 

 high, sometimes simple and leafless below, branching upwards ; at others numerous 

 corymbosely branched flowering stems start from the crown which bears a profusion 

 of rosulate leaves. Leaves 1-4 in., very variable indeed in lobation, sometimes almost 

 bipinnatifid. Heads corymbose, on very slender peduncles, erect ; ligules blue. 

 Achenes including the capillary beak \ in. long, much compressed, dull, margins most 

 minutely scabrid, tip cleft as in L. undulata ; pappus in. long, white.

 12-20-fld., outer invol. bracts few o\ate, inner linear-oblong, achenes elliptic or

 the lobes when pinnatifid, in which case the lobes are very few, membranous, almost 

 nerveless; auricles deflexed, acute, appressed to the stem. Heads in broad or narrow 

 panicles, erect; peduncles slender with few bracts; invol. bracts pale green, unequal; 

 ligules blue. Achenes \ in. including the beak, dark brown, much compressed, young
