Blasiaceae is a family of liverworts with only two species: Blasia pusilla (a circumboreal species) and Cavicularia densa (found only in Japan). The family has traditionally been classified among the Metzgeriales, but molecular cladistics suggests a placement at the base of the Marchantiopsida.
Marchantia polymorpha is a species of large thalloid liverwort in the class Marchantiopsida. M. polymorpha is highly variable in appearance and contains several subspecies. This species is dioicous, having separate male and female plants. M. polymorpha has a wide distribution and is found worldwide. Common names include common liverwort or umbrella liverwort.
Naiadita is an extinct genus of liverwort in the class Marchantiopsida with one known species, Naiadita lanceolata, that lived in the Middle Triassic period, in what is now Germany. It was first described by Peter Bellinger Brodie in 1845.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
