Oxalis dillenii ?

[BubikolRamios]

Focus on size of biggest fruit I found. O. stricta fruit should be smaller according to alpenflora.

Fruit size is absolutely useless for the determination of this Oxalis group. Rather focus on hairiness of the fruits, etc.

O. stricta (usually) has these septate, long glass hairs on the fruit. The German keys seem to bee to restrictive regarding fruit length. The Rothmaler says up to 12 (15) mm while American literature says up to 3/4 inch (19 mm).

I guess that is white ridge or is it not compared to:

From image I guess one can not say anything using Fruchtstiel 'zurückgeschlagen' oder 'gebogen'.
If I get it right gebogen is right under fruit, right ? Not at stem.

Both look like O. stricta to me because of (1) the presence of long glass hairs on the fruits (hard to see with the bright background) and (2) the pedicles which are not bent downwards as they should be for O. dillenii.
