    • ‘Their seedlings become highly ramified, passing through a creeping establishment phase consisting of a decumbent lignotuber with several basal sprouts.’
    • ‘Once the apex of a lignotuber penetrates below ground, it forms rhizomatous tissue that can generate both aerial shoots and adventitious roots.’
    • ‘The latter have developed specialized, enlarged woody growths called lignotubers, which can store nutrients and water in the earth, out of the reach of fire.’
