4. Caribean Flint and Southeastern Orange Flint.
Samples, which were collected near the border of Brazil and French‑Guinea from the Paricur (Aruac) and Galibi (Caribs) Indians, contained exclusively dark‑orange hard‑flint corn; the former quite pure, and the latter somewhat contaminated with other races. This is, so far, the most southern point where pure orange flint has been collected. I stated in the 1948 Maize News Letter that I had my doubts whether the regions of the southeastern orange flint and the Caribean orange flint should be united into one big coastal region; and this doubt still remains.
