Cyatheaceae - Wikipedia
Cyatheaceae are leptosporangiate ferns, the most familiar group of monilophytes. [3] The Cyatheaceae usually have a single, erect or creeping rhizome (stem). Their fronds (leaves) are also very large, although not as large as the tree ferns of the Marattiaceae.
Cyatheaceae - an overview | ScienceDirect Topics
Cyatheaceae. Included in the Cyatheaceae are 4–6 extant genera and more than 650 species of tree ferns in 5 major clades (Conant and Stein, 2001). The family dates from at least the Jurassic and includes forms in which the vascular system is a dictyostele with medullary bundles.

scaly tree ferns (Family Cyatheaceae) · iNaturalist
The Cyatheaceae are the scaly tree fern family and include the world's tallest tree ferns, which reach heights up to 20 m. They are also very ancient plants, appearing in the fossil record in the late Jurassic, though the modern genera likely appeared in the Cenozoic.
Cyathea - Wikipedia
Conant et al. in 1996, concluded on molecular cpDNA and morphological evidence that a system of three clades – Alsophila, Cyathea and Sphaeropteris was the most accurate reflection of evolutionary lineages within the Cyatheaceae, Alsophila being the most basal and Cyathea and Sphaeropteris derived sister groups.

Abstract. Large to very large, less often medium-sized, terrestrial ferns with short to usually long, erect, slender to robust, apically scaly stem; stele radially symmetric, forming a complicated dictyostele with much sclerenchyma on both sides of the bundles, often with accessory medullary and cortical bundles; the surface often bearing a ...

Abstract. Stem usually erect, a single arborescent trunk to ca. 20 m tall, sometimes decumbent and short-creeping, usually massive, rarely small, usually unbranched, dictyostelic with medullary bundles, indurated, bearing scales and sometimes spines; leaves usually large, ca. 2–3 m, sometimes to 5 m long, rarely small, 50 cm or less long ...
A molecular phylogeny of scaly tree ferns (Cyatheaceae)
Although most of the 600 species of tree ferns are arborescent, the group encompasses a wide range of morphological variability, from diminutive members to the giant scaly tree ferns, Cyatheaceae.
