Drosera Rechingeri
''Drosera'', which is commonly known as the sundews, is one of the largest genus, genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilage, mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.McPherson, S.R. 2008. ''Glistening Carnivores''. Redfern NaturalHistory Productions Ltd., Poole. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with Drosera rotundifolia which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Both the botanical name (from the Ancient Greek, Greek δρ ...

Drosera Tokaiensis
''Drosera tokaiensis'' is a carnivorous plant native to Japan. It is considered to be a natural hybrid of ''Drosera rotundifolia'' and ''Drosera spatulata''. These two parent species have 20 and 40 chromosomes, respectively, so recent hybrids between them are sterile, having 30 chromosomes, while the stabilized, fertile ''D. tokaiensis'' has 60 (i.e. allohexaploid). The species was previously thought to be a subspecies or variety of ''Drosera spatulata''. It is often mistaken for ''D. spatulata'' in cultivation.
