I did see something like it in a Cervantes video. My old hard drive just died and the info, although possible to find seems like too much work today. (I mean like re-loading an old harddrive)
Youtube has recently been restricting some (not all) of cervantes two, 10 part series videos. It may still be there, or not.
I do have his book open (it's the indoor/outdoor medical growers bible) on p67 it shows a very similar picture (an illustration) it's called a Stiple(bract). I didn't do any further search. Possibly this might lead you in the right direction.

Good luck in your quest

Not sure though as it has the characteristics, and is in a weird almost 6 sided shell but is covered in green still. What do I do with this type of seed? Rating: 5
