Pyrrorhiza is a genus of herbs in the family Haemodoraceae, first described as a genus in 1957. [1] [2] It contains only one known species, Pyrrorhiza neblinae, endemic to the Sierra de la Neblina in Amazonas State, Venezuela. [3] [4]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Haemodoraceae family of plants

Haemodoraceae is a family of perennial herbaceous flowering plants with 14 genera and 102 known species. It is sometimes known as the "bloodwort family". Primarily a Southern Hemisphere family, they are found in South Africa, Australia and New Guinea, and in the Americas. Perhaps the best known are the widely cultivated and unusual kangaroo paws from Australia, of the two closely related genera Anigozanthos and Macropidia.

Venezuela Republic in northern South America

Venezuela, officially the Bolivarian Republic of Venezuela, is a country on the northern coast of South America, consisting of a continental landmass and a large number of small islands and islets in the Caribbean Sea. The capital and largest urban agglomeration is the city of Caracas. It has a territorial extension of 916,445 km2. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. With this last country, the Venezuelan government maintains a claim for Guayana Esequiba over an area of 159,542 km2. For its maritime areas, it exercises sovereignty over 71,295 km2 of territorial waters, 22,224 km2 in its contiguous zone, 471,507 km2 of the Caribbean Sea and the Atlantic Ocean under the concept of exclusive economic zone, and 99,889 km2 of continental shelf. This marine area borders those of 13 states. The country has extremely high biodiversity and is ranked seventh in the world's list of nations with the most number of species. There are habitats ranging from the Andes Mountains in the west to the Amazon basin rain-forest in the south via extensive llanos plains, the Caribbean coast and the Orinoco River Delta in the east.

<i>Tibouchina</i> genus of plants

Tibouchina Aubl. is a Neotropical flowering plant genus in Melastomataceae Juss. that contains approximately 240 species. Species of this genus are herbs, shrubs or trees and typically have purple flowers. They are native to Mexico, the Caribbean, and South America where they are found as far south as northern Argentina. Members of this genus are known as glory bushes, glory trees or princess flowers. The name Tibouchina is adapted from a Guianan indigenous name for a member of this genus [2]. A recent systematic study has shown that this genus is paraphyletic.
