All cycads possess'coralloid'( meaning coral-like ) roots.
2.
Roots are called " coralloid " with an " Anabaena " symbiosis allowing nitrogen fixation.
3.
Symbiotic blue-green algae are also found in the coralloid ( i . e . upward growing ) roots.
4.
Seedlings of " Macrozamia communis " have a tuber and coralloid roots that rise up above the ground containing cyanobacteria.
5.
Seedlings of " Macrozamia spiralis " have a tuber and coralloid roots that rise up above the ground containing cyanobacteria.
6.
These branching patterns can become so extensive that a single consolidated mantle can envelop many root tips at a time, yielding tuberculate or coralloid ectomycorrhizas.
7.
Cycads are gymnosperms ( naked seeded ), meaning their fix nitrogen in association with various cyanobacteria living in the roots ( the " coralloid " roots ).
8.
Phylogenetic analyses has shown that " Ramaria " is not monophyletic, and that the characteristic coralloid shape has likely evolved several times from different ancestors.
9.
"Niebla usneoides " is distinguished by a thallus divided into numerous subtubular more or less linear shaped branches, to 4 cm high and 8 cm across, that are fringed above with spiculiform branchlets and by short coralloid isidia ( isidium ) along margins.
