What are both Kirengeshoma and Olsynium?
Kirengeshoma Kirengeshoma is a genus containing two species of plants in the hydrangea family. Both are clump-forming perennials native to Eastern Asia, with sycamore-like palmate leaves and nodding, waxy yellow flowers on slender stalks, growing in shady environments. They are grown as garden plants in temperate regions of the world.
Quisumbingia Quisumbingia is a genus of plants in the Apocynaceae first described as a genus in 1915. It was initially given the name "Petalonema", but this turned out to be an illegitimate homonym. In other words, someone else had already used the name for a very different species, in this case a cyanobacterium (formerly known as blue-green alga). So another name had to be chosen. It contains only one known species, Quisumbingia merrillii , endemic to the Philippines.
