Cottonseed oil is a cooking oil extracted from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.
Genetic studies indicate that Hawaiian cotton is related to American species of Gossypium, with its closest relative Gossypium hirsutum.

Livingstone turned to cotton from 1903: growing Egyptian cotton was unsuccessful as it was more suitable for hotter areas, but from 1906, he developed a hardier variety of Upland cotton called Nyasaland Upland, and in 1908 planted 1,000 acres at Magomero with it; this was increased to 5,000 acres by 1914.
