1. Under favorable conditions the plate stage follows very quickly after germination; there is ordinarily no filament left at the base of the prothallium. The mature prothallium usually is longer and the cushion heavier than in the Polypodiaceae. Forking of the cushion of the prothallium occurs frequently in old cultures, and in certain species may ...

ANATOMICAL STUDIES OF CYATHEA AND TRICHIPTERIS (CYATHEACEAE)
American Journal of Botany, 1977Comparative anatomical studies of the mature stems of two species each of Trichipteris and Cyathea (Cyatheaceae) are described. The outermost boundary of the stem is typically a two‐layered hypodermis.

Mating Systems of Cyatheaceae Native to Taiwan
2003The mating systems of six species of Cyatheaceae native to Taiwan were characterized by comparing isolated and paired cultures. The genetic loads were: Alsophila fenicis and A. podophylla, 100%; Sphaeropteris lepifera, 85%; A. denticulata, 76%; A. spinulosa, 61%; and A. metteniana, 46%. Genetic load and the frequency of intragametophytic selfing should

Validation of the combination Gymnosphaera gigantea (Cyatheaceae)
Phytotaxa, 2019The genus Gymnosphaera was originally established by Blume (1828) for two tree ferns from Java, Indonesia with naked sori and globular receptacles. It was emended by Copeland (1947) to contain tree ferns characterized by dark axes and exindusiate sori which were dorsal on simple veinlets.
