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

D e s c r i p t i o n. Fruit a samara, length 4.3 mm, width 1.9 mm, fruit body excluding stipe and styles 2.8 mm long, wing narrowing ( 0.3 mm) surrounding central seed body, seed body elliptical 2.1 mm long and 1.3 mm wide, two rectangular, prominent styles 1.2 mm long and 0.7 mm wide emerging apically in a V-shaped configuration.

R e m a r k s. This fruit bears a resemblance to those of Ulmus okanaganensis DENK et DILLHOFF from the early

Eocene of British Columbia and Washington ( Denk and Dillhoff 2005). However, U. okanaganensis lacks a visible wing and has styles that are more tapered and curved to the center ( Denk and Dillhoff 2005). There is also a similarity to fruits named as Ulmus sp. from the same time and area as U. okanaganensis ( Denk and Dillhoff 2005) , but the styles differ from this being more tapered and proximally curved.
