Socotra the island of happiness - Beauty will save
Cucumber tree. This tree is only found on Socotra Island, Yemen. The island is very isolated and through the process of speciation, a third of its plant life is found nowhere else on the planet. It has been described as the most alien-looking place on Earth.
Hoodia gordonii is a leafless spiny succulent plant native to South Africa Namibia. The flowers smell like rotten meat (unfortunately) are pollinated mainly by flies. There is no published scientific evidence that hoodia supplements work as an appetite suppressant. Jasjit Bindra, lead researcher for hoodia at Pfizer Pharmaceuticals, states there were indications of unwanted effects on the liver caused by other components, which could not be easily removed from the supplement.
Cereus sp. spiralis
This photo of Cereus sp. spiralis is by Chantal Wagner [What a wonderfully odd plant! Unlike some it does not look like it is from an alien landscape; absolutely terrestrial but still odd. I like the shorter, uh, trunks? stems? but the combination of short with branched tall is really compelling — 13-07-13]
