Species

See text

Maclura is closely related to the genus Cudrania, and hybrids between the two genera have been produced. Some botanists recognize a more broadly defined Maclura that includes species previously included in Cudrania and other genera of Moraceae. The genus likely originated in South America during the Paleogene.[3]

Species

Etymology

The genus is named in honor of William Maclure (1763-1840), a Scottish-born American geologist and educational reformer. President of the American Academy of Natural Sciences of Philadelphia for 22 years. Maclure made major contributions to his field, including the first true geological map of any part of North America, and was a strong advocate of universal education, especially for women.

gollark: Automated trading is cool and very weird at the same time.
gollark: I don't get it.
