Dataset of pictures showing neoplastic growth on surface roots

The photos appended constitute a dataset that describes the phenomenon of neoplastic growth on surface roots in many trees around Singapore. Incidentally, tree species in Singapore seems to have (what looks to be peculiar to me) surface roots. I am not a plant biologist, but I thought the phenomenon to be interesting for plant biologists around the world to know. Thus, I am sharing this dataset now so as not to delay research, and I may pen my thoughts on the phenomenon in a preprint at a later date. Researchers who find the phenomenon interesting can work on the problem immediately. These photos were taken with a 5 megapixel smartphone camera.
