Prairie agalinis in front of Texas lantana

with 35 comments

Prairie Agalinis Flower by Lantana Flowers 5062

After a far and then a somewhat nearer look last time at prairie agalinis, Agalinis heterophylla, here’s an even closer look at a flower of that species. Note its speckled throat and the fringe of tiny hairs on its petals. This time there are no partridge peas in the background but instead a flowering Texas lantana, Lantana urticoides. Today’s view is from September 14th in the Blunn Creek Preserve in south Austin.

Two weeks ago I learned that botanists have moved the genus Agalinis from the figwort family, Scrophulariaceae, into a family with a scientific name I don’t remember having heard of, Orobanchaceae, known as the broomrape family. Live and learn (and if you’re in the world of botany, relearn and relearn and relearn…).

An earlier and moodier globe

with 8 comments

Following the previous post about buttonbush (Cephalanthus occidentalis), here’s what one of its flower globes looks like in its formative stage. This globe was on the same buttonbush—which really is a bush, and often grows taller than a person—as the fully flowering one shown yesterday. It was overshadowed (not figuratively, as we usually use the word, but literally) when the sun briefly went behind a cloud; I aimed horizontally at nearby foliage, and the resulting photograph has quite a different feel and tonality from the image of the side-lit, fully flowering globe shown last time.

Speaking of equivalents, a term I appropriated from Alfred Stieglitz for my own purposes: the way the buds are packed around the surface of this buttonbush sphere reminds me of the way the buds of green lily (Schoenocaulon texanum) fit into that plant’s differently shaped surface, which we might describe as a gradually tapering cylinder.

(Visit the USDA website for more information about Cephalanthus occidentalis, including a clickable map showing the locations where the species grows; that turns out to be more than the whole eastern half of the U.S.)

Red yucca

with 6 comments

Buds of red yuca, Hesperaloe parviflora; click to enlarge.

Fleecy clouds last week pulled me to Mount Bonnell, a high place above the Colorado River with a vista downward onto a swathe of west Austin and upward into the unobstructed sky. Along the path I found some budding red yucca, Hesperaloe parviflora, a species that is native farther west in Texas but that has been so widely planted as an ornamental that it now occasionally grows in Travis County on its own. As is my wont, I lay on the ground so I could look up at the red yucca (which isn’t a yucca, but a member of the century-plant family) and position it against the sympathetic sky: background, background, background.

Camphorweed Lights the Way

with 11 comments

Opening bud of camphorweed, Heterotheca subaxillaris.

Although most of the structures of Austin’s former Mueller Airport have been demolished as part of the redevelopment of the site, one thing that remains is the old air traffic control tower. Those of you who don’t remember it or have never seen it can have a look at some photographs posted by the Austin American-Statesman. Then tell me if you don’t find today’s “towering” camphorweed bud, all one inch of it, a better emblem of the site. I even give you leave to see it as a resinous torch tipped with yellow flames guiding the way.

As yesterday’s post mentioned, Heterotheca subaxillaris is commonly called camphorweed because of its distinctive odor. That scent is conveyed by the sticky resin that most parts of the plant exude in tiny drops; you can see dozens of those droplets on the green bracts and stem shown here. As I wished yesterday that you could smell the plant, I wish today that you could feel its stickiness on your fingers.

Camphorweed bud and flower

with 19 comments

Bud and flower head of camphorweed, Heterotheca subaxillaris.

The Texas thistles are mostly faded now, but in spite of the drought other flowers have come into their own. Yesterday I went back to Austin’s old Mueller Airport, which ceased functioning as such in 1999 and began to get redeveloped in around 2004. Since the last plane landed there twelve years ago, multiple times that number of native plant species have returned. One that was prominent on yesterday’s visit was Heterotheca subaxillaris, commonly called camphorweed.

To give you a sense of scale, the bud at the top of the picture that’s beginning to open is perhaps a third of an inch (roughly one centimeter) across. If you take a close look at that bud, you’ll see one characteristic that sets camphorweed apart from many of its relatives in the DYC clan (that’s the exasperated acronym for “darn yellow composites,” a reference to all those yellow daisy-type flowers that can be hard to distinguish): each of the pointy bracts that surround the base of the bud is outlined in dark red.

And now I have a deep metaphysical question for you: when does a bud cease to be a bud and begin to be a flower? I can’t answer that, but I can tell you that the object in the lower portion of the photograph is no longer a bud; it’s still a flower (in the conventional sense of the word), but it’s fading. Its rays are conspicuously curled up, and its disk is beginning to dry out.

Regardless of the stage of flowerness of the plant, another distinctive characteristic of this species, and the one for which it was named, is the pleasant camphor scent imparted to the fingers of anyone touching the plant. I wish I could send that to you over the Internet, but this time technology fails me.

Texas thistle opening

with 14 comments

Opening of a Texas thistle bud; click to enlarge.

And now, after interrupting the flow of this column yesterday, I’d like to go back to the bud of a Texas thistle, Cirsium texanum, and in particular to a close-up of the way one looks when the first few disk flowers begin to poke their way out. You can compare it to a baby bird hatching out of its shell if you like, but I’m reminded of a solar flare, and the yellow background of Engelmann daisies lends itself to that sunny metaphor, even if the “flare” itself is pink. This picture, like those in the last two posts, comes from my visit to the old Union Hill Cemetery in Williamson County on May 4, 2010.

Texas thistle bud beginning to open

with 8 comments

One of the joys of the Texas thistle is an early glimpse of its tightly packed flowers when a bud begins to open.
