 note = {The leaf development and flowering processes of Symplocarpus nipponicus were studied in Iizuna Heights, central Japan. In 2003, leaves began to develop in mid-April and continued growing until late May. All leaves finally withered in early summer after the appearance of flowering (i.e. spathes). The spathes in each individual came out one after the other directly from the ground (the maximum number was three per individual) and continued flowering until early August. The duration of flowering significantly varied with the individuals., 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 41: 7-11(2004)},
