Atriplex are C-plants, with a characteristic leaf anatomy (kranz anatomy). The genus "Atriplex" is distributed nearly worldwide from subtropical to temperate and to subarctic regions. Most species-rich are Australia, North America, South America and Eurasia. Many species are halophytes and are adapted to dry environments with salty soils. The genus evolved in Middle Miocene, the C-photosynthesis pathway developed about 14.1-10.9 million years ago, when the climate became increasingly dry. The genus diversified rapidly and spread over the continents. The C"Atriplex" colonized North America probably from Eurasia during the Middle/Late Miocene, about 9.8-8.8 million years ago, and later spread to South America.
Insectivorous Plants (book) Insectivorous Plants (book) Insectivorous Plants is a book by British naturalist and evolutionary theory pioneer Charles Darwin, first published on 2 July 1875 in London. Part of a series of works by Darwin related to his theory of natural selection, the book is a study of carnivorous plants with specific attention paid to the adaptations that allow them to live in difficult conditions. It includes illustrations by Darwin himself, along with drawings by his sons George and Francis Darwin. The book chronicles Darwin's experiments with various carnivorous plants, in which he carefully studied their feeding mechanisms. Darwin tried several methods
