Cockleshell orchid

What does Cockleshell orchid look like?

This orchid grows on trees rather than in soil, with each thickened stem (pseudobulb) carrying one or two narrow, non-fleshy leaves. The flowers are distinctive: instead of the lip (labellum) sitting below the central column as in most orchids, it forms a hood over the column, making the bloom appear upside down. The flowers are long-lasting and produced one after another on a lengthening stem.
