Twenty one ramblers gathered at 8AM on this slightly muggy
morning to see what we could find at the State Botanical Garden of Georgia. Don
Hunter’s photos of today’s Ramble are here;
those that appear in this post were selected from them.

I provided the reading, an excerpt from Cheat Takes Over, by Aldo Leopold. The entire text can be found in Sand County Almanac, pp. 155-156 of the Oxford
University Press paperback edition.

Today the honey-colored hills that flank the
northwestern mountains derive their hue not from the rich and useful bunchgrass
and wheatgrass which once covered them, but from the inferior cheat which has
replaced these native grasses. The motorist who exclaims about the flowing
contours that lead his eye upward to far summits is unaware of this
substitution. It does not occur to him that hills, too, cover ruined
complexions with ecological face powder.

The cause of the substitution is
overgrazing. When the too-great herds and flocks chewed and trampled the hide
off the foothills, something had to cover the raw eroding earth. Cheat did.

Today’s route:  We took the White Trail to the Green trail;
then followed the Green until it rejoined the White. Turned right on the White
for a short distance and then turned right onto the Red (Tree Trail). At the
juncture of the Red with the White we turned right onto the White and then back
to the power line ROW and right, down the ROW back to the Dunson Garden and
back up to the parking lot through the Shade Garden, a total distance of a
little more than one mile.

Hophornbeam doubly serrate margin

At our first stop on the White trail we looked at a young Hophornbeam and pointed out
the cherry-like bark on the younger branches. Hugh also mentioned that the
leaves of the two Hornbeams in our area have “doubly serrate”
margins. That means that the leaf margin has teeth and each tooth has a smaller
tooth on its edge. (See the photo to the left.)

Near the Hophornbeam we found two Sumacs, a Smooth Sumac and
a small Winged Sumac. The Smooth Sumac is a good example of a plant with “alternate,
compound” leaves. A compound leaf is composed of many separate leaflets. But
each leaflet just looks like a simple leaf. So how do you tell a simple leaf
from a compound leaf? Just look for a bud where the leaf stem is attached to
the twig. A leaflet has no bud at this point, but a leaf does. The Sumac leaf has
many leaflets, so you have to follow it back quite a way to find the point of
attachment to the twig. There you will find the bud nestled between the base of
the leaf stem and the twig.

“Alternate” leaves means that successive leaves emerge
from the twig above one another, not opposite each other. But they don’t emerge
exactly above one another, instead they are placed slightly offset from the
leaf below (and above). This prevents upper leaves from shading lower ones. You
can see this if you look a twig bearing leaves from the end. The leaves are
arranged to minimize shading.

The difference between the Smooth Sumac and Winged Sumac?
There is a flange of leaf-like tissue, “wing”, that connects adjacent
leaflets in Winged Sumac.

As we approached the power line ROW we also noticed Black
Cherry and Yaupon Holly.

Where the power line crosses the White trail is thicket of
Dog Fennel, none of which is blooming yet. The “Fennel” in the common
name is because the thin, filamentous leaves resemble those of the herb Fennel.
But Dog Fennel is actually in the sunflower family (Asteraceae) and Fennel is
in the carrot family (Apiaceae). The flowers of Dog Fennel are very
inconspicuous, in keeping with the fact that they are wind pollinated, unusual
for a plant in the aster/sunflower family. (Wind pollinated plants typically
have greatly reduced petals — petals would just interfere with the movement of
pollen.)

Also blooming in this area we found Coffee Weed (also known
as Sicklepod), Bitterweed and Wild Petunia. In addition, Don spotted a couple
of small Parasol mushrooms.

Inside the woods we turned on the Green trail and started to
review the trees. First up was American Beech, with its smooth, gray bark and
thin, papery leaves. In this area of the trail we noticed a lot of the young
saplings are hickories, evidence that the hardwood forest is reproducing
itself. We also found a solitary specimen of Shagbark Hickory.

A parasol mushroom

The recent rains have brought out some mushrooms, but
perhaps

False Turkeytail mushrooms

not as many as would be expected. We located another parasol mushroom,
this one with a yellow centered cap, and on several twigs we found the small
Blackfooted Marasmius. Many of the fallen branches and trunks were decorated
with False Turkeytail mushrooms. These can be distinguished from the true
Turkeytail mushroom by looking at the undersurface, where the spores are
produced. If it is porous then you’ve found a true Turkeytail; if smooth, it’s
a False Turkeytail. It really takes a hand lens to see these differences.

At one spot on the trail we found signs of armadillo
presence — a roughly conical hole at the edge of the trail probably caused by
the animal sticking its snout into the ground to grab a buried grub or insect
larva.

The Muscadine vine that Avis found flowering a few weeks ago
has no fruits. Either it didn’t set any or the developing grapes have already
been consumed.

Ronnie, our sharp-eyed young rambler, spotted a small
American Toad. Ronnie is always excellent at finding creatures that the rest of
us overlook (or can’t see).

On the Red trail we noticed that more Northern Red Oaks have
fallen or are in the process of falling. Some of us wonder if the warming climate
might be responsible. Or it could also be that the poor soil in these former
agricultural fields doesn’t allow sufficient root penetration to anchor the
weight of a tall tree. Then, when they reach a certain critical height they get
blown over in thunderstorms, especially if the soil in which their roots are
anchored is softened by rainfall. Northern Red Oaks can be identified by the
presence of “ski trails” on their bark. These light colored tops of
the corky bark ridges are especially prominent toward the upper reaches of the
trunk. (Warning: Scarlet Oak also has “ski trails.”) The ski trail
mnemonic works if you remember that skiing is most popular in northern states
or countries.

Other trees that we noted on the Red trail are Black Gum,
Dogwood, and Sourwood. One of the Sourwoods we saw is extremely large for that
species, but it is not known if it is a record size. Sourwood has a very
distinctive deeply ridged bark and typically grows with a twisted trunk. It
looks as though the tree is searching out a path to the canopy instead of
growing straight up. By the way, Sourwood honey is a favorite among connoisseurs.
Among it distinguishing features is its ability to remain liquid for a long
time. Many common honeys will crystallize in a short time while sitting on the
shelf. This difference may be due to Sourwood honey’s high fructose content.
So, if you like to avoid foods that contain high-fructose corn syrup you might
want to avoid Sourwood honey. Or, actually, any honey, or, as I like to think
of it, bee-spit.

Box turtle with damaged shell

Another spot by the sharp-eyed young ramblers was an Eastern Box Turtle, this one a small female. Sexually mature male Box Turtles have red eyes. But it is possible that this turtle is immature. Also notice that the upper front edge of its shell has been damaged, probably by some predator that was looking for a tasty turtle meal.

Dwarf Pawpaw fruit

One surprise was finding a small Paw Paw patch with actual
fruits! These are very small trees, actually bushes, so they are likely to be
Dwarf Pawpaw, Asimina parviflora. The
other Paw Paw, Asimina triloba, is a
large tree and does not flower at such a small size. In addition, its fruits
are larger and more elongate than the ones we saw today. For a comparison of
the two species look at this
and this.

Mystery Mushroom

Returning to the White trail,

Same mushroom on Monday

Hugh showed us what remained
of a mystery mushroom he first saw last Monday. We still don’t know what it is,
but one guess is that it is a type of Earthstar. We are consulting other people
who know more about mushrooms than we do and will update this post when we find
out its identity. In the meantime, enjoy the bizarre pictures (Don’s on the left, Hugh’s on the right).

Redbelly snake

At the point where the White trail crosses the fence one of
Martine’s children spotted a snake in the leaf litter. It was a small Redbelly
snake, so called because its belly is a nice reddish-orange color. This small
snake was quite gentle so several of the ramblers, including those with a fear
of snakes, were able to handle it and feel its dry, smooth surface. This and a
closely related species, the Brown snake, are fairly common in our area. Both
are harmless, feeding on slugs and earthworms. They reach a maximum size of
about one foot and both species give birth to living young instead of laying
eggs. The upper surface is quite variable in color and pattern, but the
underside is uniform and varies from red to orange or intermediate shades of
color.

Beech Blight Aphids in closeup

We then encountered one of the sights that has entertained us many times — the Beech Blight Aphids that perform their “boogy-woogie” dance when disturbed. They  occupied a single branch of a Beech and obligingly did their hula for us. Don’s closeup photo clearly shows the fuzzy waxy threads that are secreted by each aphid. Presumably a potential predator is detered by a mouthful of sticky wax. Here is a Don’s movie of the aphids doing the Boogie Woogie. 

Don found several slime molds (all unidentified) growing on
most wood or the damp trail surface.

We then cut over to the power line and at the upper end,
near the locked gate, we found Dixie

Pineweed

Reindeer lichen, Pixie cup lichen and
Pineweed just starting to blossom. Further down the power line we found Common

Rose pink still blooming. Don’s photo of this also shows a

Crab spider on Rose Pink

Crab spider lurking
on the blossom, waiting to pounce on a pollinator. Just before the power line
crosses the White trail there was a fresh

Puffball

Puffball mushroom growing in the
middle of the path, which is bordered with Mountain Mint and Carolina
desert-chicory. Tim pointed out a Mississippi Kite soaring overhead.

Toward the bottom of the power line, was an unexpected
treasure — a Giant Lichen orbweaver spider. It was busy

Giant Lichen Orbweaver

feeding on its
captured prey, either a large Carpenter Bee or some kind of beetle — it was
difficult to tell without disturbing the spider. My reference to identify this
spider is Spiders of the Eastern United States, a photographic guide by W. Mike
Howell and Ronald L. Jenkins, Pearson Education, 2004. They aptly refer to this
species as “. . .this strikingly beautiful and rare spider. . .”

Next, we went back to the Dunson Native

Cranefly Orchid closeup

Flora Garden to see
the Swamp Hibiscus now in bloom. After many of the ramblers went ahead Don
spotted a Crane Fly Orchid in bloom and captured the closeup to the left.

We then adjourned until next week and many of us enjoyed our
usual conversation at Donderos’ in the visitor center.
