Karyomorophological observations on some Aroids cultivated in the Hiroshima
Botanical Garden 2.
Karyomorphological observations were studied in 11 species in the genus Amorphophallus cultivated in the Hiroshima Botanical Garden. Five species, A. henri, A. hirtus, A. kurausei, A. pingbinanensis and A. yunnanensis, had the common chromosome number of 2n=26. The chromosome numbers of the five species were recorded here for the first time. The chromosome numbers of six species, A. bulbifer (2n=39), A. kiusianus (2n=26), A. konjac (2n=26), A. muelleri (2n=39), A. paeoniifolius (2n=28) and A. titanum (2n-26) were confirmed.
