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. consanguineum germ. 70(6/6 in 2-4 w) and 40(4/7 in 8th w)-70(3/7 in 1-3 w).
