Thanks arthurm. Dendrochilum is closer to what I have. The flowers are diminutive - will have to use a magnifying glass to see them and compare to the various species before I can pinpoint it's exact ID. Glad you pointed me in the right direction.

No one wants to take a punt. Maybe a better shot of the leaves and pseudobulbs might help. Perhaps something in the Laeliinae sub-tribe. The vast numbers are against you, especially if it is a hybrid.

arthurm I did suspect that this might be a species, rather than a hybrid, as it was growing in the grounds of one of the Temples associated with the Co Loa Citadel complex. Looking up your ID, I believe you are not far off the mark, if not bang on the nail. Thank you. Fof

Thanks guys. Harvey, When I repotted them I took my cue from the fat pbulbs as to media. All my orchids are in my shade/green house so high humidity. I only water these guys maybe every 3-4 days. I'd rather grow my plants in as natural way as possible so I'm thinking about mounting them on some cedar pieces I have. That way there's not much chance of overwatering, although I consider myself an underwaterer. I'm also considering planting them in those tree fern pots. I have my Brass nodosa and my D. lundleyi in those and really like the results. I'm retired so daily watering is easy.
