M a t e r i a l. USNM PAL 622423.

L o c a l i t y. Disbrow Creek.

D e s c r i p t i o n. Winged seed linear, 8.8 mm long,

2.2 mm wide at widest point; seed body elliptical, 1.7 mm long, 0.7 mm wide; wing adnate to seed body on proximal side; seed body parallel to medial wing margin; admedial wing margin begins halfway down seed body and wing becomes widest in last quarter where distal margin forms an obtuse angle with the abmedial margin to connect with the medial margin; undulatory striations of various widths.

R e m a r k s. Pine seeds with seed bodies adnate to the wing can occur in Pinus subg. Pinus ( Wolfe and Schorn 1990) . A Diploxylon pine seed with an admedial wing less than 1 cm and seed body less than 3 mm would place this fossil in Wolfe and Schorn’s (1990) atypical Pinus 1.
