Very young Scots pine needles were found to have a higher percentage of their peristomal rim surface area covered with amorphous wax than needles sampled 5 weeks later. This, in combination with the observation of wax crystalloids (rodlets) on top of amorphous wax crusts, is interpreted as evidence for wax recrystallization.
