Deviacer wolfei MANCHESTER

Brown (1962, pl. 67, fig. 67, 7) illustrated this fruit type as “maplelike samaras, but probably of sapindaceous affinity.” The fruits are not Acer b ecause they are borne singly on the pedicel, lacking the schizocarpic condition and possess a small rudder like protuberance arising from the thickened edge of the wing near the distal edge of the seed body which is not present in Acer . A similar rudder like protuberance occurs in superficially similar fruits of extant Securidaca ( MacGinitie 1974; Pigg et al. 2008) but the basal perianth scar seen in dispersed fruits of modern Securidaca has not been observed in any of the fossil specimens. Brown’s “maplelike samaras” correspond to the extinct taxon Deviacer wolfei MANCHESTER (1994), known from the Paleogene of western North America, China, and Denmark (pers. obs.). The familial affinities are uncertain to me.
