Hi Miguel, congrats, it sound very good and I like the fact that it's easy to extract the seed
I think it should be a red m. cuspidata (not taxonomist at all, but I know that there could be a lot of variation on these kind of species, even from a yellow fruit)
For instance, if you sow 100 black e. uniflora seeds, 70 will be black, 20 red and 10 orange, as I read in a scientific report.
