A genus of large tree ferns found in tropical and subtropical regions, characterized by their tall trunks and cup-shaped structures at the base of fronds.
From Greek kyathos (cup), referring to the cup-like indentations or structures on these ferns. Named by botanists for their distinctive morphology.
Cyathea ferns can grow 20 meters tall and have existed relatively unchanged for 200 million years—they're living fossils that give us a glimpse of what prehistoric forests looked like.
