Lol. I had a boss that hated the words" never and always" so I like to use typically or usually instead as much as I can.
Actually fellas, that came from a North American Holstein tree. They are rare but hearty trees. Like most trees they come as male and female. The female trees are similar to sugar maples in that they give sap. Like the maples the sap needs to be heated and the process of heating it was invented by a fellow named Pasteur. The sap is not only delicious but healthy too. However the male Holstein trees are the only one that have nuts. Some like them as a delicacy. They call them some kind of oysters. There is even an annual festival out west where they serve them. Warning: People need to be aware of the dangers when gathering these nuts. The trees have a reaction and one of the trees near the butts will react similar to a barber chair and can give a powerful kick. One could be seriously injured while attempting to gather these nuts, so beware. You have been warned. It is said that one man was kicked so hard he set a new record when he flew well over 100 feet. Sadly he had to be rescued via ambulance.
Actually, your "cut" reminds me of eastern red cedar, i.e. juniper. I cut a downed and seasoned juniper log and was startled to find the interior all purple. The purple color does not last unless varnished/acrylic is applied and is popular with those who woodwork.
