What is "cossinia"

The gens Cossinia was a plebeian family at Rome. The gens originated at Tibur, and came to Rome early in the first century BC. None of its members ever obtained the higher offices of the state.

Cossinia is a genus of four species known to science, of rainforest trees, constituting part of the plant family Sapindaceae. The four species have an apparently ancient Gondwanan origin and present day distribution, consisting of an endemic, distinct, species in each of the southern hemisphere regions of the Mascarene Islands, Australia, New Caledonia and Fiji.

They grow naturally in rainforests, including seasonally drought–prone rainforests, and associated non–fire–adapted vegetation types.

Cossinia trifoliata trees, endemic to New Caledonia, have become vulnerable to global extinction according to the International Union for Conservation of Nature (IUCN)'s 1998 assessment.

Cossinia australiana trees, known as growing naturally only (endemic) in restricted habitat areas of central-eastern and south-eastern Queensland, Australia, have the official national and Queensland state governments' "endangered" conservation status. Within their known endemic region the trees grow naturally in habitats which have historically had their native vegetation extensively destroyed and have been further threatened.
