Tipularia discolor, or 'After the Flowers of Summer Are Gone'

Tipularia discolor, known commonly as the Cranefly Orchid, is vegetatively active during two different seasons of the year in the hardwood forests that it calls home. While most terrestrial orchids (of which T. discolor is one) hibernate during the winter and grow and flower during the warmer months of the year, this summer-flowering orchid produces its frost-and-freeze-resistant leaves during the fall, winter, and early spring, in habitats ranging from central Florida into southern Ohio. In fact, it is during the leafing stage of this orchid that it is most easily found, their solitary green leaves, deep purple underneath and often spotted with purple on top, are one of the few things green at all during the winter months. One will often encounter fairly sizable clumps of plants during this time of year.



In spring, the leaves fade as the trees overhead begin to leaf out again and diminish the light reaching the forest floor. If the plant has stored enough nutrients in its chain of underground corms, it may decide to flower in summer (typically around July-August). The flowering stems blend very well with their surrounding environment, so they are quite difficult to spot, even when in full flower. Curiously, only about ten percent of the plants seen in winter time will flower in the summer. They obviously seem to have very fertile seed, considering the size of the colonies typically seen in winter.



Their flowers are curiously asymmetrical, with the dorsal sepal and lip skewed to one side of the central axis, and one of the lateral petals typically twisted down to overlap its corresponding lateral sepal. The spur extending from the back of the lip is filled with nectar. Research done on the pollinators (W. P. Stoutamire 1978) of this orchid indicates that these flowers are pollinated by noctuid moths. I have observed a faint, sweet night fragrance in the flowers, which is consistent with this research.

Now Playing In a Swamp Near You and Bewitched, Part III

Now to bring the topic back to orchids (since, after all, this is an orchid-related blog). Late fall in north and central Florida usually does not have much to offer orchid-wise...most terrestrials are wrapping up for the year, storing whatever they can in their underground portions prior to the first below-freezing night, which usually does the above-ground parts in. Starting in October in northern Florida, and wrapping up in December in southern Florida, two common woodland species come into their own during this sparse time--Spiranthes odorata and Ponthieva racemosa, known by their common names as Fragrant Ladies' Tresses and the Shadow Witch Orchid. You can see some earlier posts of Shadow Witch flowers and plants to this blog under the titles Bewitched, Part I and Bewitched, Part II. Both are members of the subfamily Spiranthoideae and tribe Cranichideae, but the former is classified in subtribe Spiranthinae and the latter in subtribe Cranichidinae. Both have evergreen basal rosettes of leaves and grow in rather swampy areas and both reproduce vegetatively via runners, as well as sexually via flowers and seeds. Because of their vegetative reproductive habit, both can tend to form extensive colonies over time, although I have observed S. odorata as being a bit more aggressive in colony forming than P. racemosa Both species are pleasantly fragrant, with P. racemosa smelling faintly of citrus while S. odorata smells most strongly of vanilla scented baby powder.

Three of my children and I visited a well-known site for these species...this same general area is home to Malaxis spicata, Platythelys querceticola, Listera australis, and Corallorhiza wisteriana as well. I would not be surprised if Epidendrum magnoliae were found growing in the trees overhead. Here are some photographs taken of these two species:

Trail Tales (or Stuff I've Seen While Hunting For Orchids), Part 3

On the day we went to see Pteroglossaspis pottsii in flower, we saw a Butterfly Pea (Centrosema virginianum) in flower:



This flower one of many 'orchid imposters' we have in the state of Florida, with lovely, two-inch-long (5 cm long), purple flowers that, to an untrained eye, may appear to be an orchid. This flower, in fact, belongs to a member of the pea family, which is about as far away from being an orchid as you can get.

Get Your Ghost On...

'Tis the season for things of a ghoulish nature. Celebrate it by showing off your love for Florida's orchids...



Lurking deep in the swamps of Florida, the ghost orchid (Dendrophylax lindenii) haunts largely inaccessible places with its large, white and pale green flowers. To add to its mystique, it is fragrant only in the dark hours of the night to lure its pollinators (night-flying moths) to its narrow phial of nectar.

These jet-black t-shirts capture the essence of Florida's ghost orchid and help in a small fashion with the costs of running the web-site, trips into the field (requiring fuel for both vehicles and hikers), etc. Own your own ghost orchid t-shirt by following the link below:

Trail Tales (or Stuff I've Seen While Hunting For Orchids), Part 2

A week or two later, one of my older daughters, Sarah, and I went back to the same preserve from part number 1 to try to photograph one of the two native species of orchids found here (Habenaria odontopetala and Epidendrum magnoliae). I was recounting the tale from the last time, instructing her in no uncertain terms that she should keep an eye on the ground carefully to make sure she didn't step on a cottonmouth. As I was pontificating, Sarah was trying to quietly get my attention, "Dad....Dad....Dad". "What?" I say. "Look ahead up the trail". Right there, about 100 feet away, was a young black bear. I managed to get out my camera and fire off a shot before he/she noticed us and scampered off quickly into the woods (the Floridian population of Ursus americanus is known for its relative shyness). This was only the second time in my life I've seen a black bear...once, I saw a young bear scampering away in the Tallahassee area as I was walking in the woods.

Here is the photo from the day:

Trail Tales (or Stuff I've Seen While Hunting For Orchids), Part 1

One fine morning, while hiking back out of a local wildlife sanctuary, I was about to step on what I thought was a stick, when, suddenly, my eyes detected a distinctively non-stick-like pattern. It turned out to be a youngish cottonmouth (Agkistrodon piscivorus piscivorus) sunning itself in the trail. Thankfully, these snakes are not nearly as aggressive as legend says they are (it is my understanding that they get this mistaken reputation from highly aggressive, non-poisonous water snakes). A quick flick with my walking stick near the tail, and this fellow(ette) decided the swamp on the other side of the trail was more to his/her liking.


As of yet, I've not been bitten by a venomous snake...I'm praying that it stays that way.

Ghost Orchid Painting - Experimenting with Watercolor Pencils

I was inspired to try something by a post several years ago on the previous instantiation of Misti Little's blog (Oceanic Wilderness in my blogroll). In the post, she was interviewing an artist friend who used watercolor pastels to do painting and was describing how they gave her the precision of pastel drawing with the final result looking like a watercolor after water was applied to the paper. This intrigued me immensely, so I filed this away in my brain. Fast-forward to about two weeks ago, where I was picking up some art supplies for my kids--I spied a box of watercolor pencils.

I figured I'd give them a whirl. I immediately fixed upon Miguel Urquia's Ghost Orchid as my subject of interest. Here's the photo below:



And here's the result. I feel like it's pretty good for my first effort, but I definitely have some room for improvement:



Here are a couple of detail shots:





Let me know what you think in the comments, but please remember, this is my first attempt at this medium.
