Shaw (in Stearn, Gen. Epimedium, 299-306. 2002) recognized two subspecies of Podophyllum aurantiocaule, which he separated into subsp. aurantiocaule ("Leaf lobes long, obovate to lanceolate; sinuses deep, penetrating 1/2-2/3 of radius; flowers usually in petiole fork; anthers 5-7.5(-9) mm long") and subsp. furfuraceum ("Leaf lobes short, triangular, sinuses shallow penetrating 1/4-1/3 of radius; flowers borne on petiole; anthers 3.5-4.5 mm").
