[Taxacom] Please help identify mystery plant

[Monique Reed]

Taxacomers,

An ulabeled Riker mount of an unusual leaf/leaflet was found among some old teaching lab materials in our Biology Department.  It looks like a single leaf with reproductive structures on the margins.  The venation is also unusual.  Does anyone recognize the plant at:

The leaf or leaflet is 6-7 cm long.

Thanks,
