Cyathea

***Cyathea*** est genus pteridophytorum et typus ordinis Cyathealium. Plurimae *Cyatheae* sunt plantae terrestres, singulo cauli alto plerumque praeditae. Raro, truncus dividitur vel serpit. Multis speciebus ad fundamentum trunci est massa radicum fibrosarum. Geographica generis distributio est pantropica. Plusquam 470 species in habitationibus a silvis pluvialibus tropicis ad silvas temperatas inveniuntur.

Nomen *Cyathea* ex Graeco *kyatheion* 'poculum' deducitur, quod ad cupulatos in inferiore latere frondorum soros spectat.

Notissimae species sunt *Cyathea brownii, Cyathea cooperi, Cyathea dealbata, Cyathea medullaris.*

## Classificatio
Haec classificatio investigationes Conant et aliorum anni 1996 consequitur, qui, ob indicia cpDNA molecularia et morphologica concluserunt systema trium cladorum—*Alsophila, Cyathea, Sphaeropteris*, quo *Alsophila* est primum, et *Cyathea Sphaeropterisque* ex gregibus sororibus deducuntur—esse accuratissimam stirpium evolutionariarum intra Cyatheaceas descriptionem.
