The Catkin Yew (Amentotaxus argotaenia) is a species in the genus Amentotaxus. It is currently classified as Near Threatened on the IUCN Red List. Typically found in temperate and boreal forests, often at higher elevations.

Hapalosiphon luteolus is a filamentous, branching cyanobacterium found in freshwater habitats, damp soil, and moist terrestrial environments including peat bogs and wetland margins. It produces a yellowish pigmentation and forms heterocysts capable of nitrogen fixation. This species contributes to nitrogen cycling in wetland and semi-aquatic ecosystems where it forms part of benthic microbial communities.
