"I agree that without fruits (typically nutlets) some Boraginaceae can be difficult.
My first thoughts are an Eritrichium rather than Myosotis asiatica (syn. Myosotis alpestris subsp. asiatica)
which is the only Myosotis recorded from Ladakh.
I seem to detect green, immature fruits in two of the images, showing bristles. If so, this means will be an Eritrichium -
of which 6 are recorded for Ladakh: E.canum, E.fruticulosum, E.hemisphaericum, E.patens, E.thymifolium
and E.villosum; it is not E.villosum (syn. E.nanum subsp. villosum) or E.hemisphaericum.
Eritrichium, according to 'Flowers of the Himalaya' have ovoid nutlets, 3-angled with winged margins, with or
without hooked bristles.
Will need to check out the others.
I must locate my copy of Boraginaceae of Pakistan and see if this makes things clearer.
Best Wishes,
