Seeds laterally compressed, subspheroidal, slightly ovate in lateral view, smooth, semi-inflated, occasionally with a prominent facet on one side (fig. 7B), ca. 4.5mmhigh, ca. 3.6mm long, and ca. 3 mm wide, apically truncated by a distinct hilar scar. Hilar scar prominent, elliptical (fig. 7A) to occasionally pyriform (fig. 7B) in outline, ca. 1 mm wide and ca. 2 mm long, encircled by a pronounced lip 0.4–1 mm in height. Four to eight vascular bundles arranged in bilateral rows visible fromthe hilar scar (fig. 7A6). Raphal vasculature passes from the hilar scar longitudinally through the seed coat, on the side opposite from micropyle, about one-third to two-thirds the length of the seed and curves basally to merge with chalaza and/or endosperm (fig. 7B7). Seed coat relatively thick, ca. 0.6 mm.
Named after Bruce Tiffney, recognizing his significant work on seeds of Staphyleaceae and the fossil record of Cenozoic seeds in general.
