Elatostema is a genus of flowering plants containing approximately 350 known species in the nettle family Urticaceae, native to tropical forest clearings throughout Australasia, Asia and Africa.
 There may be as many as 1,000 species of this little-known genus, which is susceptible to deforestation and other forms of human exploitation.
 Some species, for instance the recently discovered "E. fengshanense", show unusual adaptations to growing in deep shade in caves.
 DNA analysis suggests that the three genera "Elastostema", "Pellionia", and "Pilea" be grouped together as one.
Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia.
 It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753.
 Linnaeus thought that the flowers looked like a fountain of wax.
 From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998).
 They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Pilea, with 600–715 species, is the largest genus in the plant family Urticaceae and one of the larger genera in the Urticales and eudicot rosids.
