 note = {Leaf developement and flowering processes of Symplocarpus foetidus var. latissimus H. Hara and S. nabekuraensis Otsuka et K. Inoue were studied in northern Nagano Prefecture, central Japan. In 2004, in S. foetidus, flowering occured in early April before leaf development. Then, leaves developed rapidly with continued growth until late May. In 2002, with S. nabekuraensis, flowering and leaf developement occured simultaneously in early June. The flowering duration of S. foetidus was longer than that of S. nabekuraensis. In both species, two spathes, in selected individuals, bloomed simultaneously., Article, 信州大学教育学部附属志賀自然教育研究施設研究業績 44: 7-10(2007)},
