Porroglossum meridionale

It seems to be Porroglossum season since almost all of mine are in bloom at the moment.  Porroglossum meridionale is another species from this genus of insect-trapping flowers.  The flowers have hinged lips and  when disturbed by a small insect the lip suddenly snaps up trapping the insect against the column, effecting pollination.  Most of the pictures show the lip open but the last two photos show the lip up against the column.  The plant is 6 cm tall, the flower spikes 10 cm in length, and the flowers 1.5 cm.  It comes from Peru.
