As others have pointed out plants do get 'cancer', but I doubt this is what you are seeing. I have seen something very like what you describe, on the UC Berkeley campus. If the tree in question was *planted* as part of landscaping work, the strange growth pattern may well be deliberate! By vigorously pruning all larger branches above a certain point on a tree it can be induced to form just such a burl with numerous small twigs growing out of it - sort of an elevated bush. Berkeley has entire groves of Western Sycamore pruned in this way - it makes for an odd sort of high hedge. Now if the tree you saw was 'wild' I am probably off base. -- --------------- uunet!tdatirv!sarima (Stanley Friesen)
