Sepal Trimery in Euryale ferox Salisb. Germplasm Collected from Manipur, North-Eastern India

Anubha Kumari, Vidyanath Jha*, Lokendra Kumar, Vinod Kumar Gupta

Abstract


Euryale ferox plant grown at the ICAR Research Centre for Makhana, Darbhanga from a germplasm collected from Manipur (north eastern India) was found to develop a flower with only three sepals and three whorls of petals. Sepal trimery is considered a primitive character belonging to monocots as against the normal presence of tetramery that is a derived character found in dicots. The present finding establishes that E. ferox belongs to the group of basal angiosperms, having a combination of monocot and dicot characters and shows its similarity with another Nymphaeid genera like Victoria, Cabomba and Brasenia. While Victoria and Brasenia are reported to contain 3-4 sepals, Cabomba is reported to have an exclusive number of 3 sepals only. Thus, E. ferox shows its proximity to Cabomba so far as sepal trimery is considered.
