I find the following clear differences:

Vinca major                                                                                  Vinca minor (from USA in our database)

1. Plants loosely spreading on ground with longer internodes       Plants compactly spreading on ground with shorter internodes           
2. Leaves broadly ovate, 5-9 cm long, 3/4 to as broad                  Leaves elliptic to oblong, 2-4 cm long, about 1/2 as broad                      
3. Leaf base truncate or subcordate, margin minutely ciliate         Leaf base rounded or cuneate, margin not ciliate
4. Pedicel 3-5 cm long                                                                  Pedicel 1-2 cm long
5. Flower 3-5 cm in diam                                                              Flower 2.5-3 cm in diam.

Pl. go through ‎Vinca (‎Apocynaceae) page with images of species (done by me) in efloraofindia.

If you find any mis-identification, pl. let us know. If anybody can send images of other species of this genera (for incorporation in the website), if any, it will be really nice.

Also, if anybody is interested to take up the activity of inserting images on efloraofindia pages from efloraofindia posts, pl. let us know.
