Petroravenia eseptata is a plant species native to Argentina. It is also type species for its genus, Petroravenia, first described in 1994. [1] [2]

Argentina Federal republic in South America

Argentina, officially the Argentine Republic, is a country located mostly in the southern half of South America. Sharing the bulk of the Southern Cone with Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of 2,780,400 km2 (1,073,500 sq mi), Argentina is the eighth-largest country in the world, the fourth largest in the Americas, and the largest Spanish-speaking nation. The sovereign state is subdivided into twenty-three provinces and one autonomous city, Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over part of Antarctica, the Falkland Islands, and South Georgia and the South Sandwich Islands.

Type (biology) Specimen(s) to which a scientific name is formally attached

In biology, a type is a particular specimen of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralize the defining features of that particular taxon. In older usage, a type was a taxon rather than a specimen.

Petroravenia is a genus of plants in the Brassicaceae, first described in 1994. There are to date only two species proposed as members of the genus:

Petroravenia eseptata is a perennial herb spreading by means of underground rhizomes. All the above-ground vegetative parts are covered with finely branched hairs. Leaves are sessile (without petiolr), ovate to elliptical, up to 4 mm (0.16 inches) long. Petals 4, white, narrow. Fruits are egg-shaped, up to 5 mm (0.1 inches) long, lacking septum, with 8-18 seeds per fruit. [1] [3]

In biology, a septum is a wall, dividing a cavity or structure into smaller ones.
