| | Cyathea - Wikipedia, the free encyclopedia |
 | | Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales. |
 | | The genus name Cyathea is from the Greek kyatheion, meaning "little cup", and refers to the cup-shaped sori on the underside of the fronds. |
 | | Conant concluded, based on molecular cpDNA and morphological evidence, that a system of three clades—Alsophila, Cyathea and Sphaeropteris, whereby Alsophila is most basal and Cyathea and Sphaeropteris are derived sister groups—is the most accurate reflection of evolutionary lineages within the Cyatheaceae. |
