"The other bush produces a species of bulb of oblong form, bearing the indigenous name of "yamph," and if it possesses less nutritive principles than the camas, it is much the better for one thing, -- it can be eaten raw."
"The yamph has a longer and smaller bulb than the camas, though not quite as nutritious, and may be eaten raw."
"We have not noticed on this trip a single growing plant or specimen of the camas, the cowse, or yamph."
