Acc to keys (Cote vs SVKI) this must be L.5- or L. virsol. but as achenes are definitely hairy at apex and in color an olive drab with indicated darker motlings (not black as desc for L. virosa or "purple-black," see 6-26-33) it seems most likely L.8- But note that no loose as will Cote. Lower lvs are obly to 8 x1.7 cm shallowly sinuate lobed. Then upper lvs properly small are more nearly lanceolate and are entire except for the fine but pronounced periclinal edges (lower lvs have similar edges) Base of st & midribs of lvs beneath def setose precisely to and mid-rib silvery white. Lvs (as far as can be judged from col specimen) do stand mostly with one edge up. Spec col is 2½ ft (taller ones were seen) with several ascending branches from near base. The paneculate inf[or] occupies 1/4 t of the main st and when buds had developed will evidently extend much lower. Achenes shaped as ill Cote #3½ x 1 mm with a white beak ] 4½ mm.
