Nancy B. Rybicki, Vincent Lai, editor(s)
2018, Open-File Report 2018-1075
SummaryFrequent occurrence of intermediate forms and poor knowledge on the variability of characters have caused some difficulties in the taxonomy of Trapa in Japan. Thus I made a preliminary analysis on the variation of nuts collected from 21 populations in Southwestern Japan. Attention was paid to some morphometrical characters of...
