Arisaema (Araceae). The Asiatic species were received as dried berries in midwinter and germ. readily at 70 after WC for 7 d. The American species exhibited complex behavior. Germination is hypogeal in all species. The seed forms a corm and root system before sending up the single true leaf. This first true leaf is a single leaflet in A. dracontium, experiments are needed on WC with detergents. Treatment with GA-3 was also tried with the GA-3 applied after the 7 d WC and using seeds collected in October. The data were 70 GA-3(40% in 2-4 w) and 70(22% in 2-5 w). The GA-3 seedlings were normal
