' The plant in question is the Eskimo potato, also known as alpine sweetvetch, or Hedysarum alpinum. The hardy little plant grows across Alaska and northern Canada. McCandless, along with plenty of Alaska natives, had relied on the carrot-like roots as a staple. But Krakauer could find no record of people eating the seeds. The L-canavanine toxin could be why.

"Once the roots became unpalatable in midsummer, the natives did not eat these seeds," Krakauer explains. "So, they knew something that we didn't." '
