Which genus has more species, Carex or Bloomeria?
Carex Carex is a vast genus of almost 2,000 species of grassy plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the Cyperaceae family are also called sedges, however those of genus "Carex" may be called "true" sedges, and it is the most species-rich genus in the family. The study of "Carex" is known as caricology.
Volvox carteri Volvox carteri F.Stein 1873 is a species of colonial green algae in the order Volvocales. "V. carteri" forms large spherical colonies, or coenobium, of 2000-6000 "Chlamydomonas" type cells. Colonies contain mostly somatic cells plus a smaller number of gametes in female or male colonies. In addition to female colonies with eggs and male colonies with sperm bundles, purely vegetative colonies exist. All three types of colonies may also have specialized cells called gonidia for asexual reproduction of the colony.
