<p><i><a href="//commons.wikimedia.org/wiki/Holcoglossum_amesianum" title="Holcoglossum amesianum">Holcoglossum amesianum</a></i>. As the ID of this plant may be problematic:
It was a fairly large plant, with semi-terete V-shaped leaves, and the spike I photographed was fairly robust, maybe a foot long.

I'm wondering: could it be a hybrid??
