Arachis monticola is a close relative of the domesticated peanut ("Arachis hypogaea"). Besides the peanut, it is the only other tetraploid species in the genus "Arachis". It is thought to be the immediate wild ancestor of peanut, although it may be a weedy form, descended from cultivated peanuts.
Cultivated peanuts have created other forms of peanuts that are sometimes more weedy. 
This statement is correct because the last sentence says that: It is thought to be the immediate wild ancestor of peanut, although it may be a weedy form, descended from cultivated peanuts. I rephrased this to write it backwards.
