Regular branching patterns

Lepidogyna hodgsoniae (syn., Lepidolaena hodgsoniae), from above - The leaves are covered with a dense mass of fine hairs (cilia) believed to aid in the absorption and retention of water. This liverwort is found in cool, moist areas throughout New Zealand.

Lepidogyna hodgsoniae (syn., Lepidolaena hodgsoniae) - Some liverworts form branches left and right and on one plane, creating a pinnate (herringbone) pattern with distinctive ranks or hierarchies of branching

Cushion forming

Isotachis intortifolia - If a plug is removed from a cushion the inner region is seen to be composed of decaying stems and leaves, rich in humus and able to retain water.

Isotachis intortifolia - Many liverworts form closely-spaced, erect stems. Their continued growth results in thick, dense cushions.
