Some friends come back in late spring from S. Argentina with few seeds of a Sisyrinchium. After their images I would say S. patagonicum only that the leaves don’t quite fit. I’m not really familiar with the flora of the region and on chileflora (where usually I go to check on South American species) there is only one image showing capsules. Other opinions greatly appreciated, thank you.

Gabriela, we have great difficulty with some of the sisyrinchiums we find in southern Argentina. The plant is definitely not S. patagonicum or S. chilense, both of which have their anthers fused along the complete length of the filaments. It looks like S. arenarium, which is quite a variable species.

Thanks Martin - that's a good character at least to remove some species from the 'maybe' list. I found a good photo gallery with South American species -

They have both S. arenarium and S. patagonicum - clearly shows the fused filaments.

I got into the habit of keeping photographic records of all seeds, sometimes it helps in ID-ing the species later.
