Discussion

Glycine max is cultivated for the extraction of oil, for the edible seeds, and for animal fodder; it is estimated that it provides about one-third of all protein used by humans. It is not known as a wild plant in its native China, and is believed to have originated as a selection from G. soja Siebold & Zuccarini. The latter is a twining herb with seeds 2.5–4 mm. Glycine max probably is not truly naturalized in Canada and some of the states listed for the flora area.
