Taxonomic notes: Sometimes misidentified as L. chrysantha due to long peduncles or fruit stalks. Distinguished from L. chrysantha by: hollow stem pith (vs. solid), very short petioles, abundant yellow pubescence throughout plant, separate ovaries, and distribution mainly along Baekdudaegan (vs. L. chrysantha with solid pith, relatively long petioles, early-deciduous leaf pubescence, partially fused lower ovaries, and southern distribution).
