据本瑟姆在其著作《巴西植物志》中记述,“花生栽培种(A,hypogaea)似由巴西的六种野生近缘种中的一种演化而形成的,但在这六个野生种中,很少有像栽培种那样,具有子房柄入土结实成熟的这种稀有的特性。这一特性恐怕是栽培种在进化过程中新产生的习性”。德次道尔写道,不论新、旧两大陆任何地域,也没有栽培种的野生型植物的分布,恩格勒与普兰特尔两人认为,花生栽培种是由巴西的野生种Arachis Prostrate进化而来。莱因哈特也认为花生栽培种的野生型在巴西, According to Bentham, in his book The Flora of Brazil, “A, hypogaea appears to have evolved from one of six wild relatives in Brazil, but in these six wild species , There are few such rare features as the cultivated species that have mature sturgeons in the ovary of the stalk, a feature that I am afraid is the new habit of cultivated species in the evolutionary process. ” Desdeau wrote that in both the new and old continents, there is no distribution of cultivars of wild type plants, and both Engler and Plantere argue that peanut cultivars have evolved from the Brazilian wild species Arachis Prostrate Come. Reinhart also believes that the wild type of peanut cultivars in Brazil,
