Dr. Carl Luer, author of The Native Orchids of Florida, was first made aware of this orchid in the late 1950's. It was not until several years later that he found plants of this species in flower, after several unsuccessful attempts. Described by Luer in 1966 and named Triphora craigheadii after the late Dr. Frank Craighead, Sr., entomologist and botanist at the Everglades National Park, this orchid is only known from a few localities in central Florida (and one or two possible localities from southern Florida). It may grow in many places, but it is so small as to be virtually undetectable, quietly inhabiting the understory of the understory of mixed oak/pine/juniper forests, where it grows as a terrestrial or occasionally a lithophyte over the limestone underlayment where it makes its home. As a genus, Triphoras are often quite small. This species is a liliputian even among Triphoras. I have included an image below with a U.S. penny placed in the shot to give an idea of the sense of scale.
To make it even harder to find these plants, they only bloom during the last week of June and first week or two of July. Were it not for the guidance of a good friend, I would not have these photographs to present to you today. Look for an update to the Florida Native Orchids website within the next few weeks with more information on this species.
Enjoy!

Down in south Florida, in areas in and around the Big Cypress Swamp, the ghost orchids are beginning to bloom. Their accepted scientific name is now Dendrophylax lindenii (changed from Polyrrhiza lindenii and Polyradicion lindenii, but they are sometimes still referenced by their old names). It should be noted that nearly all land where these orchids grow are either federally or state protected lands. In addition, they are on the state endangered species list, so taking these from the wild can land someone in jail, or hit them with stiff fines. Further, the plants taken from the wild are very likely to die a rapid and miserable death away from their native environment. Taking wild plants is also entirely pointless, as one can purchase legally seed-grown seedling plants from several vendors, including Oak Hill Gardens, for a very reasonable price. Keep a legally purchased seedling alive and growing for 3-4 years and you're likely to have your first flower.
While there is a substantial population in the Fakahatchee Strand State Park, plants are usually quite inaccessible, requiring grueling hikes through swampy areas infested with mosquitoes, alligators and poisonous snakes (both rattlesnakes and water moccasins are seen frequently in these areas). In addition, those who know where plants are found are very reluctant to share this information anymore, as plants continue to turn up missing...so, the actions of a few very selfish individuals has spoiled it for the rest of us...there are no more public tours led by park staff into the deep swamps to see ghost orchids in bloom. This is truly a shame.
However, all hope is not lost to see a ghost orchid in bloom. In fact, there is one ghost orchid whose location has been made publicly known...it is the world-famous Corkscrew "Super" Ghost Orchid...one of the largest plants ever seen, with up to twelve flowers open simultaneously. It is well off the boardwalk and high up a tree, and thus not easily accessible. When in flower, park staff at the Corkscrew Swamp Sanctuary will place spotting scopes on the boardwalk so that it can be easily seen. As I understand it, it is not yet in flower (it usually opens up in mid-July)...I will post an announcement to this blog as soon as I hear anything more.

While out photographing the previous Hexalectris spicata flowers, my daughters and I noticed one spike in the area that was decidedly paler than the other emerging spikes (which were already turning a dusky red). It was several weeks away from flower, so we flagged it for a colleague to observe when he was in the area...being closer, he was able to keep tabs on the flowers as they grew, so we were able to return when they had finally opened. This is a nearly alba form of Hexalectris spicata, with only the faintest color on the tepals and lip. A true albino form, fma. wilderi, would have no color at all, while fma. albolabia would have no coloration on the lip of an otherwise normally colored flower. This form has no formal description as of yet, although something very similar is pictured in Paul Martin Brown's Wild Orchids of Florida in the section on this species.
You can read more about this species on my website (and view the typical color form) at:

Canon Digital Rebel XTi, f22, ISO100, 1/200s. Flash through a diffuser. Composite of two photographs, one of the upper flower and one of the lower flower.
Unfortunately, most of the spike had wilted due to what appeared to be the nips of a hungry insectoid creature (although it could've been a fungal or bacterial rot), so these were the only good flowers remaining.

Florida's dancing lady orchid...Tolumnia bahamensis.
This little beauty, related to Oncidium, used to be found in quite a few wild areas in the coastal scrub in a very restricted area of southeastern coastal Florida...although due to its very restricted habitat, it has never been common, even in its heyday. Heavy development has all but wiped this species out, but a few plants still eke out a tenuous existence within a local state park and a very few remaining empty lots. While the land is protected where this species grows, collection by poachers continues to be a very real threat. This species is considered endangered in the state of Florida and is thus protected by state law.
For someone fortunate enough to be out in the field in one of these few localities, the search for plants is quite daunting...their heads of whitish flowers reach to the edge of the wild rosemary (not related to the spice) and palmetto scrub beneath an overstory of scrubby pine trees. To add to the insult for this species, seed pods seem to form only rarely, perhaps pointing to a decline in their natural pollinators...I would suspect copious use of pesticides in surrounding housing developments to keep boring, green lawns looking their best may be to blame, but that's only pure conjecture on my part. This is a more common species in the Bahamas, from whence its specific epithet is derived. It is also related to (and some would consider it synonymous with) Tol. variegata, which can readily be found in cultivation.
The plants themselves grow like a typical equitant Oncidium (i.e. Tolumnia) with somewhat narrower leaves arranged in small fans around microscopic pseudobulbs. Each fan is joined to the last by a rather long isthmus of rhizome (atypical for Tolumnias), which can actually look like an emerging flower spike before the leaves start to fan out at the tip. They grow in the bases of rosemary, palmetto, and/or pine twigs very low to the ground, with their root tips actually buried beneath the pine needle litter in the sand.
Each flower is between 1/2 and one inch across, depending on the plant (Luer shows a photo of a sheet covered with numerous individual flowers, showing marked variation in flower shape and size, in his epic work, The Native Orchids of Florida). The flowers are somewhat unpleasantly scented--the best way I can describe it is that it is similar to the smell of the commercial herbicide, Round-Up.
You can find out more about this species on its profile page on the Florida Native and Naturalized Orchid Website:
Tolumnia bahamensis
While vouchered specimens of this species have been found in many counties in the state of Florida, this species is rarely seen, as it blends in quite well with the surrounding forest, making it difficult to see until you are quite close. Then, the true beauty of these flowers is revealed. Each is a little over an inch wide and scented pleasingly of baby powder. I would consider this perhaps the second- or third-most attractive terrestrial orchid in the state of Florida (first is Cleistes bifaria, the Rosebud Orchid, which holds a special place in my heart as one of my first-observed native orchids).
The plants themselves bear no leaves, instead living in a mycotrophic relationship with fungi hosted (and consumed) in the coral-like roots. These fungi, in turn, send out mycelia throughout the soil and infect the roots of other plants, forming a network of nutrients funneled from one plant to another in a complex "nutrient highway" beneath the forest floor. While many orchids after the earliest seedling stage will bear leaves and begin to perform some of their own nutrient manufacture through photosynthesis, they never lose their fungal relationship entirely. The coralroots never grow beyond this earliest relationship, relying their entire lives on nutrients gathered from their fungi. Because of this delicate relationship, coralroots will die in short order if transplanted to another site.

AKA Calopogon tuberosus, this particular flower was just shy of being a true alba, with just a pale flush of color in the lip and the bases of the sepals/petals. Typical flower color for these is a medium pink, with variants ranging from true alba to eye-searing magenta. Located in the same general vicinity as the Rose Pogonias posted a few days ago.

Pogonia ophioglossoides, known as the Rose Pogonia or Snakemouth Orchid, is one of the most far-ranging orchids on the North American continent, being found as far north as southern Canada and as far south as south-central Florida. It is a relatively common orchid of moist, acid bogs, wet meadows, and pinelands, blooming at the height of spring (early summer in the north). Plants most of the time have a single flower (sometimes lightly scented of raspberries), but occasionally, two- and even three-flowered plants will appear within large, robust colonies. This particular plant was growing along a roadside in west-central Florida.
While it is wrapping up its blooming in central Florida, northern Florida should see this beauty in bloom for several more weeks.
Enjoy!

So, without further ado, here are the flowers of the shadow witch. These are flowers that I have wanted to see in person ever since seeing them in Luer's landmark book, The Native Orchids of Florida. First, we have the entire inflorescence. The flowers are about 1/2 inch (approx. 1 cm) across, ranging from whitish-cream to mint-green in color. They have a faint, citrusy fragrance. 
and here is a flower close-up. Each individual flower is bent backwards to form a small landing platform. The lip faces inward toward the spike, with the petals and sepals forming a flat surface beneath the column with its curious tooth overlapping the small pollinia. All of the floral parts have a crystalline, sparkling texture. The ovaries and remainder of the flowering stem (as well as the backs of the flowers) are covered in fine hairs.
So, there you have a close-up view of these bewitching flowers.
Enjoy!
