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. triphyllum germ. best if the seed was left outdoors in the berries until March 1 and then WC (7 d or 14 d gave similar results). This seed germ. 95% in 1-3 w at 70 and 95% in April-May in outdoor treatment. The leaf developed in the 2nd w after germination. Seed collected in October and immediately WC for 7 d germ. 70(23%)- 40-70(77% in 1-3 w) and none in either 40-70 or outdoor treatment. Light had no effect. As with
