The Blackboard Tree (Alstonia scholaris) is a species in the genus Alstonia. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests and tropical and subtropical dry broadleaf forests within the Oceanian biogeographic realm.

Phacus hamelii is a unicellular, photosynthetic euglenoid alga with a flattened, asymmetric cell body containing chloroplasts and a distinctive posterior tail-like extension. It inhabits freshwater environments including ponds, ditches, and slow-moving water bodies rich in organic matter. Like other Phacus species, it uses a flagellum for locomotion and can perform both photosynthesis and heterotrophic feeding.
