Thank you Surajit. Can see that a lot of time & work has gone into this. Agree with Dr. Vijayasankar. This could be Mallotus polycarpa [syn Trewia polycarpa]. Can't really comment cause I have never seen this tree before, but it definitely is not Trewia nudiflora. With regards, Neil Soares.

Also this tree does not look like Trewia nudiflora to me. My photographs of Trewia nudiflora are available in the archives of this group.

A search in the internet tells me that these blisters are caused by a fungus - Taphrina (http://www.britannica.com/EBchecked/topic/333773/leaf-blister). Please read this post along with my earlier posts at https://groups.google.com/forum/?fromgroups#!topic/indiantreepix/eJFCyYVnbe0 and at https://groups.google.com/forum/?fromgroups#!topic/indiantreepix/cl3zczbsij8 to establish the ID of the infected tree. Moreover, a majority of these roadside trees are infected with these blisters, some severely while others are mildly. Species : Trewia nudiflora L. Habit & Habitat : tree, roadside plantation Date : 15-03-2012, 10-22 a.m. Place : Gobra (Hooghly), WB ID help : Please see the links given in the text Regards, Surajit Koley
