Reproduction is the most vital event in the life cycle of angiospermic plants. To accomplish this,the process of pollination is carriedby different methods. The biotic agents involved in the process of pollinationare rewarded in many ways. One of which is nectar produced in nectary. Nectaries are specialized tissues that secrete a sugary fluid involved in interactions with animals.The two types of nectaries are present namely, extrafloral and floral. The present work deals with the detailed structure of nectaries studied in four different plants of family Cucurbitaceae. The studies revealed thatthe extrafloral nectaries are found on leaf lamina and stipules while the floral nectaries on the flower. The anatomical structurestated the differences in male and female flower nectaries. The male flower consists of epidermis and 8-10 layers of secretory parenchyma while the female flower tissue revealed more up-to 10-12 layers of secretory parenchyma and outer non-secretory 10-14 layered parenchymatous zone.
