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.
Growing pains Children with growing pains do not have signs of any systemic diseases (such as fever or skin rashes), any abnormal pain sensations, tender spots, or joint disorders. Children do not have growing pains if the pain worsens over time, persists during the daytime, only involves one limb, or is located in a joint. It should be excluded if the child is limping, loses the ability to walk, or has physical signs that suggest other medical conditions. Childhood-onset restless legs syndrome is sometimes misdiagnosed as growing pains. Other possible causes of pain in the limbs include injuries, infections, benign tumors such
