There are events: points in time and space, at nodes of the grid.

The branches form roots at nodes when they touch the ground.

The stems trail along the ground and can set root at the nodes.

In this proof, we start with given external currents at the nodes.

In texture it is quite hairy, especially on the leaves and at the nodes.

The branches divide off at the nodes which are often swollen.

In figure 5, some possible anchor points are shown as wires attached at the nodes.

It readily roots at the nodes when they come into contact with the soil.

Roots develop in abundance at the nodes on the stems.

The main stems grow along the ground, rooting at the nodes.
