Q. What can I do if I need help in tree id?
A. You can go through our list of species that has details on species characters, including common names in various Indian languages, and a photograph. You can also write to us on with a couple of good photographs (including close-up of leaves, flowers and fruits if they are present) of the tree that you wish to identify.

Q. What can I do if I need help in identifying a phenophase?
A. Often multiple phenophases are present on a tree at any time. If you look closely, you may be able to distinguish between them, such as fresh and mature leaves. Flower buds and unripe fruits can at times be sources of confusion, and if you are not able to tell them apart right away, it is best to observe the tree over multiple days. The flower buds progress into open flowers, unripe fruits, and ripe fruits. You will easily learn these as you watch the tree closely.
