Orchid Hunting in Northern California and Oregon

Continuing our trip through Washington, Oregon and northern California, we visited a favorite site in California where we photographed both the Few-flowered Rein Orchis, Platanthera sparsiflora, and the California Lady's Slipper, Cypripedium californicum, both of which have a decided preference for wet, serpentine soils.  We found both in abundance and also found a few Phantom Orchids, Cephalanthera austiniae.  At a site in Oregon on our way back we found Epipactis gigantea, the Stream Orchid or Chatterbox.

Three Native Orchids in the Northern California Siskiyous

July 9-12 was our big trip for the summer; down along the Oregon coast, into northern California to see the Redwoods and a day in the Siskiyou Mountains of northern California and southern Oregon for some orchid hunting, though we were also looking for Cobra Lilies and other wildflowers that we had not seen before.

The Siskiyous are part of the Klamath Mountains and are a  wonderful area with a unique flora that is due to its serpentine outcrops and soils rich in magnesium, nickel and chromium.  We spent a day in them and most of the day exploring the Knopki Creek Road in northern California looking for orchids there.

We drove nearly 40 miles on forest service roads, many of them very rough, but found all that we were looking for and more, including two orchid species that we had not seen before, one the strikingly beautiful California Lady's Slipper and the other the rather prosaic Few-flowered Rein Orchis.

These two orchids are often found in serpentine areas, the Lady's Slipper exclusively in such areas, and are often associated with the Cobra Lily, a carnivorous plant.  We found all three growing together in several different places and spent hours photographing them, but they were not all we found.

Early on in our explorations we found a few Phantom Orchids, Cephalanthera austiniae, on a bank with some beautiful pink lilies that we were not able to identify.  These orchid are rather uncommon, but we seem to have seen them everywhere this summer.  They are so unusual they are always good to see.

The California Lady's Slipper, Cypripedium californicum, is found only in serpentine areas and reaches the northern limits of its range in the Siskiyous.  It has small flowers but makes up for that by producing an abundance of blooms, as many as twenty per spike, the most of any native Lady's Slipper.

The plants grow to 120 cm tall, but those we saw were shorter, none more than about 75 cm.  The flowers themselves are 10 cm, variable in color from yellowish green through green and bronze, most of them with pink markings at the opening of the lip, a few without any markings.

The Few-flowered Rein Orchis, Platanthera sparsiflora, was always found growing with them, though we also found it growing by itself in the dampest areas and often in large clumps.  It grows to 75 cm, with 2 cm flowers, green and distinctive in shape with many per spike in spite of its name.

 The green flowered Platantheras can be difficult to identify but this should not be.  Its flowers are hooded, the dorsal sepal and petals forming the hood, with the long lip and spur point down beneath the hood and the rest of the flower folded back forming a bearded, cowled monk's head.

It was nice to see two new orchids and one old friend, and we hope to revisit the area another time and do some more orchid hunting in this amazing and wonderful area.  In fact, we spent so much time in this one area that we had little time left for exploring in other areas both in California and Oregon.

Few-flowered Rein Orchis (Platanthera sparsifolia)

The Few-Flowered Rein Orchis is another of the green Platantheras, all of which are rather uninspiring as orchids go and often somewhat difficult to tell apart.  This one was rather easy to identify, but nothing to brag about, though a new species for us.

The species reaches the northern edge of its distribution in southern Washington State, but we saw it in northern California and southern Oregon, where is is abundant, growing in clumps of hundreds of stems in some places, and scattered stems elsewhere.

The plant with its flower spikes can be quite tall, growing over 75 cm, but is often shorter, especially in strong sunlight.  Like most of the plants in the genus it likes wet areas and is often found growing in serpentine seeps, as we found it growing on our recent trip.

When found in serpentine areas it is often associated with the California Lady's Slipper (Cypripedium californicum) and the Cobra Lily (Darlingtonia californicum).  In fact, in nearly every location where we found Cobra Lilies, we also found this species.

The flowers are around 2 cm in size and the petals and dorsal sepal form a "hood" at the top of the flower, with the narrow lip hanging below and the lip-length spur behind the lip.  The rest of the flower is more or less curved back.  The flower count varied from few to as many as 45 flowers.

The name sparsiflora means "few-flowered" but it is difficult to see why the name was given since the flower count is no lower than the other green-flowered Platantheras.  But whatever the reason for the name it is relatively easy to identify this species from the shape of the flowers.
