Cyathea - Classification

Classification

The classification below follows the findings of Conant et al. in 1996. 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.
