Here are some of the cultivars of Cucumis sativus

Dosakai cucumber is nearly rounded yellow cucumber from India, commonly cooked as curry, added to sambar, daal and soup and in making pickle dosa-aavakaaya. Also grown and sold in California where it was photographed.

Cucumis-sativus-sativus-pickle-Calfonia-1 the small fruited form commonly used for making pickles.

Cucumis-sativus-WANGAAN_Rajasthan-2 This interesting cultivar commonly grown and sold in Raasthan has no information available on net, or known to me. My daughter-in-law who hails from Karanpur near Ganganagar brought these fruits known as Wangaan, commonly used as cucumber there. Any information would be welcomed.
