1934 was an unusual season for flowering plants in Oregon. The author collected samples throughout the county and found that early flowering plants, those plants most affected by the sun, flowered an average of two months earlier than usual; trees flowered 37 days earlier; water plants flowered a month earlier; bog plants, affected more by the sun's rays than water plants, but less than the plants of meadows and open hills, flowered 41 days earlier; while Hudsonian-Subalpine Zone plants flowered 32 days earlier. Bog plants and Hudsonian alpine plants that blossom in April, May and June were 60 to 100 days earlier than usual while flowers which first appeared in July, August, and September were 30 to 1 day early. Results of the author’s study are discussed here.Item #901627
