In writing about far northern bulbous plants I was thinking about monocots alone, but Dennis is correct that some Alaskan Claytonia species have underground storage structures. There is also a Hedysarum (Fabaceae, pea family) that produces tubers collected for food by Native people. Veratrum has structures that one could call bulbs, in the broad sense, and there are some aquatic plants in Alaska with storage structures too. Lloydia, which I mentioned, is the one I've seen growing farthest north, near Nome, but two Claytonia species extend north of the Brooks Range onto the Arctic SLope; one of them is C. tuberosa, whose root is also used as food. ex-Alaskan Jane McGary Portland, Oregon, USA At 07:47 AM 2/3/2015, you wrote: >There are about 7 species of Claytonia that occur in the northern parts of >Alaska, Yukon & Northwest Territories.
