Aloe Juvenna
''Aloe juvenna'' (The "Tiger-tooth Aloe") is a species of plant in the genus ''Aloe''. It is popular in cultivation but extremely rare in its natural habitat in Kenya. Distribution and habitat It is endemic to Kenya in East Africa. Here it is restricted to a small rocky area in the mountainous south west of the country, near the border with Tanzania. Discovery and history in cultivation It has long been common in cultivation, but its origin was not known. The first recorded cultivated specimens were in South Africa, but although there were rumours that it had come from Kenya, its origins were a mystery even then. It was first believed to be a juvenile Aloe, due to its small size, and it was labelled "juvenna" ("juvenile") for this reason. However that label eventually became its formal name. Later, it was thought to be a hybrid perhaps of '' Aloe distans'' with '' Haworthia coarctata'' or a species of ''Astroloba''. It underwent genetic testing in the 1970s and, when it was ...

Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...
