FRYE collected about 1000 specimens of mosses, lichens and algae in S.E. Alaska, while RIGG obtained a collection chiefly of cryptogams at Yakutat Bay, Prince William Sd and the Shumagin Is.  RIGG visited Alaska also in 1929, when he collected at Pillar Bay, Kuiu I in 1932, and probably in other years as well.  FOSTER collected bryophytes and lichens at Wrangell.   The collections are in Univ. of Washington.  A list of the lichens was included in a publication by HERRE (Publ. Puget Sound Biol. St. 2, 1919). FRYE published a paper »The kelp beds of southeast Alaska» in F. K. CAMERON, »Potash from Kelp» p. 60-104 (U. S. Dept. of Agricult. Rep. No. 100, 1914).  RIGG published three papers on Alaskan vegetation: »Notes on the Flora of some Alaskan Sphagnum Bogs» (Plant World 17, 1914); »The effect of the Katmai eruption on marine vegetation» (Science 40, 1914) and »Some raised bogs of southeastern Alaska with notes on flat bogs and muskegs» (Amer. Journ. Bot. 24, 1937).
