    Myrmecophila often needs very bright light, 4000fc +, higher than almost any commonly cultivated orchid. The 70% shadecloth may be too much. Try gradually moving to higher light level. I would also cut the fertilizer back to every other watering. And realize it can take a full growth cycle or more for a change in conditions to trigger flowering. The plant appears to be in excellent condition, maybe almost too lush. Myrmecophila often looks a little dry and beaten up when they bloom well. Good luck.

    I agree with Kirk. I think that in good light conditions, the pseudobulbs should be yellow. My Mcp is gradually grown in full sun in summer.
    Maybe it needs a rest period (less water, no fertilizer), like some other Myrmecophila, when the new shoot is mature, to induce the spike growth.

    Agree with the above key for flowering must give adequate light apart from fertilizer and temperature.

    Thank you for input, Kirk,Eric. I moved the above 3 weeks ago from the conditions you suggested. Full sun, in the usual hot humid conditions here in Brisbane. I thought, maybe this was too hot, as we were approaching summer. Now I realise, this orchid grows in hot equatorial conditions on rocks in Central America (is this correct?). So should I move the orchid back to it's previous position?

    70 percent shadecloth is a bit too much...try 0-30 percent and you may be surprised

    Annette, none of my species types are large enough to bloom yet, got mine as divisions or small plants, I thought their blooming season to be summer/fall, but that could be species dependent also. I 've been treating them like a vanda when it comes to watering and they seem happy.
