'''''Cyathea''''' é um [[Género (biologia)|gênero]] de [[Feto arbóreo|samambaias arbóreas]], o gênero típico da ordem de [[samambaia]]s [[Cyatheales]].

O nome do gênero ''Cyathea'' é derivado do [[Língua grega|grego]] ''kyatheion'', que significa "pequeno copo", e refere-se aos [[soro]]s em forma de xícara na parte inferior das folhas.

== Descrição ==
As espécies de ''Cyathea'' são principalmente samambaias terrestres, geralmente com um único caule alto. Raramente, o tronco pode ser ramificado ou rasteiro. Muitas espécies também desenvolvem uma massa fibrosa de raízes na base do tronco.

O gênero tem distribuição [[pantropical]], com mais de 470 espécies. Eles crescem em habitats que variam de [[Floresta tropical pluvial|florestas tropicais]] a [[Bosque|florestas temperadas]].

== Classificação ==
Conant ''et al.'' em 1996, concluiu sobre [[ADN plastídico|o cpDNA]] molecular e evidências morfológicas de que um sistema de três clados - ''Alsophila'', ''Cyathea'' e ''Sphaeropteris'' era o reflexo mais preciso das linhagens evolutivas dentro das [[Cyatheaceae]], sendo ''Alsophila'' o mais basal e grupos irmãos derivados de ''Cyathea'' e ''Sphaeropteris''.<ref name="Conant1996">{{Citar livro|título=Pteridology in perspective|ultimo=Conant|primeiro=D.S.|ultimo2=Raubeson|primeiro2=L.A.|ultimo3=Attwood|primeiro3=D.K.|ultimo4=Perera|primeiro4=S.|ultimo5=Zimmer|primeiro5=E.A.|ultimo6=Sweere|data=1996|editora=Royal Botanic Gardens|editor-sobrenome=Camus|editor-nome1=R.J.|localização=Kew, U.K.|páginas=231–248|capitulo=Phylogenetic and evolutionary implications of combined analysis of DNA and morphology in the Cyatheaceae|isbn=9781900347099|editor-sobrenome2=Gibby|editor-sobrenome3=Johns|editor-nome4=M.}}</ref> Na classificação Pteridophyte Phylogeny Group de 2016 (PPG I), estes são aceitos como gêneros separados, ''Alsophila'', ''Cyathea'' e ''Sphaeropteris''.
