Most of the posts on tubers are in a yam thread. Since yams aren't generally regarded as edible raw, I figured there should be a raw tubers thread. I'll start it off with Eskimo potato (aka Indian potato), which can be eaten raw and of which there are reports of at least three varieties. Because they can be eaten raw, Eskimo potatoes qualify as raw Paleo/Instincto per the definition of Ray Audette and Instinctos.
Eskimo potato (aka Indian potato)http://en.wikipedia.org/wiki/Eskimo_potato"The Eskimo potato is a type of edible plant that grows in the northern areas of Canada and Alaska. The plant's scientific is name variously attributed as either Claytonia tuberosa[1][2] (Inuit: oatkuk[3]) or Hedysarum alpinum (Inuit: mashu[3]). Both species have a range in the northern area of North America, have edible roots, and have been documented to have been used as a food source by Inuit peoples.[4] Due to its nutritional qualities, the eskimo potato is one of many edible foods listed in survival guides, such as the US Army's field manual Survival[2], and is used in modern times to subsist in nature; for instance, Christopher McCandless used the plant as a food source while he survived in the Alaska wilderness.[5]"

being eaten, raw and cooked by natives." The variety of Eskimo potato with pink flowers has the most Internet images.

Greenland Eskimo (domestic) potato farmer. I didn't know that potatoes could be farmed in Greenland.
Limited potatoes OK in Stefansson's idea of an "Eskimo diet":"While there were in pre-white times many Eskimos who used no vegetables, there were some, especially in Labrador and Alaska, who got as many calories from vegetables as the Holiday Diet does; so, even with a few things like lettuce and
potato, we may well name this regimen for the Eskimos. The same diet is described in my 1921 book Friendly Arctic, as used and enjoyed by whites who, like the Eskimos, found it nonfattening, and thus a good reducing menu." (The Fat of the Land, 1960, p. xxvi)
