Gemina is a genus of green alga.
Some species include:
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
Legio XIV Gemina was a legion of the Imperial Roman army, levied by Julius Caesar in 57 BC. The cognomen Gemina (Twinned) was added when the legion was combined with another understrength legion after the Battle of Actium. The cognomen Martia Victrix was added following their service in the Pannonian War c. AD 9 and the defeat of Boudicca in AD 61. The emblem of the legion was the Capricorn, as with many of the legions levied by Caesar.
Legio X Gemina, was a legion of the Imperial Roman army. It was one of the four legions used by Julius Caesar in 58 BC, for his invasion of Gaul. There are still records of the X Gemina in Vienna in the beginning of the 5th century. The legion symbol was a bull. Early on in its history, the legion was called X Equestris (mounted), because Caesar once used the legionaries as cavalry.
Legio XIII Gemina, in English the 13th Twin Legion was a legion of the Imperial Roman army. It was one of Julius Caesar's key units in Gaul and in the civil war, and was the legion with which he crossed the Rubicon in January, perhaps the 10th, 49 BC. The legion appears to have still been in existence in the 5th century AD. Its symbol was the lion.
