Mimosa hostilis seeds?

[Sublimer]

Can Mimosa Hostilis seeds be very dark brown? My online searches show a light brown seed. Mimosa Pudica seeds appear dark brown. Can you get very dark MH seeds or are they Pudica if they are super dark?

My M.Hostilis produce almost black seeds.

I too am wondering if there is a better way to distinguish MP from MH based on seeds alone.
