Ponerorchis graminifolia from seed?

[Subrosa]

Does anyone have any knowledge of whether this orchid can be propagated ex-vitro on organic substrates? Given the time this plant has been in cultivation I strongly suspect this s possible, although I can find no real information at all regarding propagation by seed. It's certain that I have one pod maturing, with many more possibles coming along.

From this paper:

Cryopreservation of immature seeds of Ponerorchis Graminifolia var. Suzukiana by vitrification

Immature seeds (6 weeks after self-pollination) 'showed higher germination and protocorm formation than mature seeds' (17 weeks).

The seeds can be cultured in

'0.2% gellan gum-solidified New Dogashima Medium - ND medium with 58 mM sucrose'

That's more info than I was able to track down! Thanks!

Subrosa - is yours one of the selectively bred forms? Or closer to wild stock? Any photos?
