D e s c r i p t i o n. Winged seed linear, 11.7 mm long, 5.3 mm wide at widest; seed body elliptical 3.8 mm long, 2.3 mm wide oriented with long axis parallel to medial edge; seed body on proximal side of seed; seed body contains numerous, round resin vesicles; abmedial margin begins approximately one quarter of the way up seed body extending so widest area of wing is distal; distal edge straight; medial edge convex in distal quarter.
R e m a r k s. Winged seeds with resin vesicles and with the wings widest in the distal half belong to Abies ( Wolfe and Schorn 1990) . Abies pollen is known from the early Eocene McAbee and Quilchena floras of British Columbia ( Dillhoff et al. 2005, Lowe et al. 2018, Mathewes et al. 2016) and Yellowstone, Wyoming ( Wing 1987). Macrofossils are known from the early Eocene McAbee and Falkland floras of British Columbia ( Dillhoff et al. 2005, Lowe et al. 2018, Smith et al. 2012), Republic flora of Washington ( Pigg et al. 2011), Green River Formation ( Brown 1929) and Oligocene Beaverhead flora of Montana ( Wing 1987) . Abies is also recognized based on seeds and foliage from the mid-Eocene Thunder Mountain flora of Idaho ( Axelrod 1998). Although the identity of some of the specimens that were attributed to Abies deweyensis AXELROD , by Axelrod (1998) has been questioned due to disarticulated parts and a lack of diagnostic features ( Erwin and Schorn 2005).
