Xo. 17149), is entirely green with the exception of anarrow line on the sinus margin; another variety there, the Rejalgar(S. P. I. Xo. 20970), has a petiole reddish at the base and bluish inthe middle, while the blade has a violet margin, and in the young leafthe veins are shaded red beneath; the natives do not cultivate this-latter variety, but gather the young leaves and petioles for greens andto mix with their stews, while the tubers are also mashed and madeinto a gruel, according to Dr. Edward Palmer.

The color of the tubers varies insideaccording to their size and maturity from pale yellow to orange; theexterior is rough, with numerous small eyes. The Gengihrilla yautia of Porto Rico (S. P. I.
