Moreae is a tribe within the plant family Moraceae. It includes 6–10 genera and 70–80 species, including Morus, the genus that includes the mulberries, and Maclura, the genus that includes the Osage orange.
Recent work suggests that the tribe is

Taxonomy
The tribe is based on Morus, the genus that includes the mulberries. The name Morus was first published by Carl Linnaeus in 1753 in Species Plantarum.[4]
Cornelis Berg included eight genera in the tribe Moreae—
About 40 generic names have been coined for these species, resulting in a situation with many genera and few species. In 1962 British botanist E. J. H. Corner reworked this arrangement, merging many genera. This resulting in an expansion of several genera, most notably Maclura, Streblus and Trophis. These were further reorganised by Berg in the 1980s. He found that while it was easy to define the tribe (based on the presence of urticaceous stamens), the definitions of the genera were more challenging.[2]

Evolutionary history
Few fossils can be definitively assigned to the Moreae. Fruits from the upper Eocene, Miocene and Tertiary have been assigned to Broussonetia, and fruit matching modern Morus have been found in the early Eocene. Based on rates of molecular evolution in chloroplast and nuclear genes, the Moreae s.s. is estimated to be about 59–79 million years old. Nyree Zerega and colleagues proposed a Laurasian origin for the Moreae s.s., with three separate colonisations of South America (by Sorocea, Bagassa and Trophis) and a later colonisation of Africa by Milicia.[1]
Distribution
Most genera in the tribe are predominantly tropical, sometimes with a few temperate species (like Maclura). Two genera, Broussonetia and Morus, are predominantly temperate.[2]
