Species & genera pages of Bignoniaceae are now with images : 1 post by 1 author.
Species & genera pages of (Bignoniaceae) in efloraofindia are now with images.
This work was done by mainly me, … & …
It is one of the big families in efi & the work started on 30.6.16 in a systematic way & was completed today only on 15.7.16.
It involves inserting images on around 63 species pages (say around 600 images) & 33 genera pages. It also involved a lot of cleansing work, correctly identify some of the threads, putting them at their proper places, proper formatting of the species pages etc.
I request our members to pl. take up one family each & try to make efloraofindia more constructive. We will be rendering what ever assistance is required by the members, in this matter.
