D e s c r i p t i o n. Linear winged seed 6.2–14.0 mm long, 4.0– 5.2 mm wide; widest portion of wing in proximal 1/3; seed body triangular with acute proximal point to elliptical and concave depression on surface; seed body at proximal end of seed, 2.3–3.3 mm long, 1.1–1.9 mm at widest point; distal edge of seed body rounded; wing linearly striated.

R e m a r k s. Winged seeds with straight, rather than undulating striations, proximal seed bodies with distal portions of the seed bodies rounded and wings that are widest in the proximal half conform to Larix ( Wolfe and Schorn 1990) . The shape of the seeds resembles that of the modern taxa Larix kaempferi (LAMB.) CARRIÈRE , and Larix decidua var. polonica (RACIB. ex WÓYCICKI) OSTENF. et SYRACH ( LePage and Basinger 1991) .
