Taxonomy, Diversity and Distribution of the Genus Cucumis L. in India

The eco-geographic distribution and taxonomy of 17 taxa of Cucumis L. was investigated based on the study of 978 herbarium sheets in seven major Indian herbaria and germplasm collection of 261 accessions. Distribution map was plotted based on authentic identification of herbarium specimens and field observations under natural conditions. Areas of higher concentration/richness have been worked out for individual taxon. Morphological, ecological, phenological features and economic importance are discussed. The ideal time for collection of germplasm is indicated.
