Probably this is due to the, it is a case of extreme changes in direction of growth, almost 90 degrees, in most cases solves nodes angular deviation of several degrees. (photo)
Pengine hii ni kutokana na, ni kesi ya mabadiliko uliokithiri katika mwelekeo wa ukuaji, karibu 90 digrii, katika kesi nyingi solves nodes angular kupotoka ya digrii kadhaa. (photo)
