This beaut article in The Conversation describes efforts by botanist Greg Leach and colleagues at the Northern Territory Herbarium to identify a specimen of an unusual tree collected in Kakadu National Park.
Eventually, with help from the collection at Kew Herbarium and after the discovery of another specimen in the NT Herbarium's GOK (God only knows) Box, it was named as a new, threatened species in the genus Hildegardia (Malvaceae).
Twelve species of Hildegardia are recognised: one from Cuba, three from Africa, four from Madagascar and one each from India, the Philippines, Indonesia and Australia (biogeographers: go figure).
Almost the entire generic lineage seems to be verging on extinction.
