Monopodial Branching

a type of branching in plants, in which the growth of the main axis continues throughout a plant’s life, as do the second-order and third-order branches developing on the main axis. The growth of the main axis may cease temporarily under unfavorable conditions, for example, during the winter. Monopodial branching is characteristic of many seed plants (spruce, oak, lily of the valley), green algae, fungi, and leafy mosses.
