She-who-must-be-obeyed and I had a short break in Jasper in May, and on one of our morning walks, we came across some Calypso orchids. These are small orchids with a circumpolar distribution. Each plant usually bears only a single bloom on a 10 to 15cm long stem that rises out of a single 3 to 5cm pleated basal leaf. The Calypso orchid grows from a single bulb-like corm that has a few slender roots that are dependent on mycorrhizal fungi. The bloom consists of a pouch-like and lobed labellum with five slender sepals and petals. The distribution is circumpolar.
There were a few single specimens sparsely distributed near the trailhead (I will keep the location secret because these orchids are very susceptible to disturbance and subject to harvesting for the international orchid collectors trade), and we were delighted to find them. I struggled to find a good specimen near the path that was not surrounded by grass or other distracting plants or twigs. I was looking for a nice uniform background and eventually managed to get a satisfactory shot of a bloom, despite the wayward breezes.
After that photo session, we moved on. Eventually, we reached a lake and began to explore the rocky shore. While I was taking some bug photos my wife moved on out of sight. Later, as I was trying some intimate landscape images, I heard her calling out to me. Not sure what to expect, I bounded across the rocks like a true hero, expecting to have to rescue a bull moose or grizzly bear from her disapproval. As I neared her she waved me over to a shrubby patch. I tiptoed over, camera at the ready. I cautiously peered into the thicket, and then reeled back in surprise. Rather than the skunk I was expecting, there, on the ground, was a huge …(wait for it)
…patch of fairy slippers!!!! Yes, the same Calypso orchids that I had been struggling to photograph before were now spread before me like a grand feast on the table of the gods.
Photographing a patch this size effectively has its own problems. It can be hard to find a pleasing composition which that doesn’t have a background cluttered with more orchids!
I played with depth of field to try to isolate an attractive scene, with varying success. After spending half an hour photographing orchids in this patch, we moved on again. We found several other groupings, but none compared in size this group. Below are some of the resulting images, that please me in different ways.
These orchid flowers are an example of deceptive pollination, in that they have the colour and scent to attract bees, but there is no nectar reward. Bees do learn to avoid these flowers, but in the process, they have already delivered the pollinia (a pollen package) to another orchid so fertilization can be successful.
Below, Jan Styka‘s image of Calypso. Certainly, She-who-must-be-obeyed would approve, “It must be SPF 50 she’s applying”, she would say.
(Calypso is the nymph (a nature spirit) from Greek mythology, who kept Odysseus captive on the island of Ogygia for several years. At some point (perhaps when suffering from sunstroke?) this hero begins to miss his wife, Penelope. The goddess Athena, his protector, asks Zeus to release Odysseus from the island, and, in concordance with the Chain of Being, Zeus sends the messenger Hermes to tell Calypso to set Odysseus free. Protesting, she complains how the gods hate it when goddesses apply sunscreen to mortals, but she finally submits to the will of the Master of the Universe and sends Odysseus packing.)
