We went camping at Thaba Monate near Warmbaths when we saw this round wooden flowery growth on a thorny tree with silver green velvety leaves. My brother in law climbed into the tree, pick it and then cleaned it with his pocket knife and a brush, painted some veneer on and mounted it.
You get different shapes and sizes. This one is open but the one at home as more closed (with the claws/points.,,,, almost touching)
Can you please find out from which tree this is? My husband believes the growth is due to a virus or bacterial infection on the tree.
