At last!
Obtained a cluster of leafless bulb from a road-side slope after a small landslide, we grew this species after dividing into pots.
The plant grew profusely with many leaves but did not flower at all. That was many cycles for the last nine years.
Last week, one of the pot flowered. Only then we can safely describe and name this species.
We shot an HD Video of the Geodorum citrinum here.
