Abstract. The veins of plant leaves exhibit a large variety of morphologies. They are often thought to result
from their growth in a concentration scalar field. It is shown here that the topology of these patterns rather
corresponds to what is expected from growth in a tensorial stress field. This is demonstrated by analogic
