Some consider this tree to be the most beautiful flowering tree in the world, as noted by Priscilla in the comments with her photo on Flickr. Meriania nobilis is a small tree (to 15m/49 ft.) native to a narrow elevational range (1900m-2900m) within the central and western Colombian mountains.
iNaturalist contains many additional photographs of amarraboyo, but perhaps the photograph most illustrative of its beauty (at least in a cultivated setting) is from this commercial site: Meriania nobilis via Strange Wonderful Things.
Meriania nobilis was scientifically described and named by the Colombian botanist José Jerónimo Triana in 1873: Meriania nobilis in Transactions of the Linnean Society of London. On the topic of Linnaeus, I believe he only had one genus named after him (Linnaea). Meriania, however, is one of two genera–the other being Sibylla–named in honour of the German-born 17-century naturalist Maria Sibylla Merian.
Because of her careful observations and documentation of the metamorphosis of the butterfly, she is considered by David Attenborough to be among the most significant contributors to the field of entomology
