Black and Red Seed (no velum)

Here is a lovely black and red seed. Photographed on the cut tip of a pin. Sadly, I do not have a record of the seed's name, so any help with this distinct specimen would be appreciated. This seed came from a 100 year old collection of seeds used as reference by the old Bureau of Biological Survey. They would dissect vertebrate stomachs and then determine what they ate by identifying the seeds there in...thus the need for the seed collection. Am going through the unprocessed specimens while we get our new set up running. This dates to 2014. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200 USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
