Sadleria cyatheoides Sadleria cyatheoides, commonly known as amaumau fern or ʻ amaʻ u, is a fern species in the family Blechnaceae, in the eupolypods II clade of the order Polypodiales, in the class Polypodiopsida. It is endemic to Hawaii and inhabits lava flows, open areas, and wet forests on all major islands up to an altitude of 1676 m . Reaching a height of 0.9 - and a trunk diameter of 7.5 - , ʻ amaʻ u resembles a small tree fern. Kīlauea's Halemaʻ umaʻ u Crater is named for this species.

Cyanotrama Cyanotrama is a fungal genus in the Hymenochaetales order. The genus is monotypic, containing the single species Cyanotrama rimosa, widely distributed in western North America. It has also been collected in single occasions in Ethiopia and Iran. The fungus causes a white rot in conifers, especially junipers. "C. rimosa" was originally named "Poria rimos" in 1920 by William Alphonso Murrill, and later known as "Diplomitoporus rimosus". Molecular work revealed that the species was aligned not with the polyporoid fungi as previously assumed, but rather with the hymenochaetoid fungi, and "Cyanotrama" was created to contain it. The genus name refers to the strong cyanophilic reaction (stainable with blue dyes) of the skeletal hyphae, particularly noticeable in the trama.

Cycadales Cycadales is an order of seed plants that includes all the extant cycads. These plants typically have a stout and woody (ligneous) trunk with a crown of large, hard and stiff, evergreen leaves. They usually have pinnate leaves. The individual plants are either all male or all female (dioecious). Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long, with some specimens known to be as much as 1,000 years old. Because of the superficial resemblance, they are sometimes confused with and mistaken for palms or ferns, but are only distantly related to either.
