Clark Hill Wildlife Management Area: Early Spring Wildflowers

-->
April 6th, 2013. We drove over to the Clark Hill Wildlife Management Area to look for Adder’s Tongue ferns. We didn’t find any but were treated to a number of early spring wildflowers.

Green-and-gold (Chrysogonum virginianum)

We saw only one small patch of these on the north side of the road just around the bend from the check-in station. This species is found in many counties in north Georgia as well as some counties in south Georgia.










Birdfoot Violet (Viola pedata)

These were growing on the south side of the road just around the bend from the check-in station and extended for one-quarter to one-half a mile. The area on the north side of the road had been burned recently so it wasn’t possible to determine if these also grew on that side of the road. This species is also found more frequently in north Georgia counties than in south Georgia counties






An unusual white variant


Yellow Stargrass, Hairy Yellow Stargrass, Common Stargrass (Hypoxis hirsuta)

There were just a couple of Yellow Stargrass plants on the top of the embankment among the Birdfoot Violets. One was doing well; the other was not thriving. This species may be found in many counties throughout Georgia






Rattlesnakeweed, Veiny Hawkweed (Hieracium venosum)

Rattlesnake Weed plants are easily recognized by the characteristic leaf coloration. These were just setting buds and will be flowering before long. This species is found more frequently in counties in north Georgia than in south Georgia.






Trumpet Honeysuckle (Lonicera sempervirens)

We found Trumpet Honeysuckle blooming in a couple of places. This species may be found in counties throughout Georgia.


The characteristic perfoliate leaves





Hog Plum, Flatwoods Plum (Prunus umbellata)

These trees were blooming in many places in the WMA. This particular plant was only three to four feet high which made photographing the flowers easy. This species may be found in counties throughout Georgia except for the most northen counties.







Resurrection Fern, Scaly Polypody (Pleopeltis polypodioides)

We found some nice specimens of Resurrection Fern, a species that may be found in counties throughout Georgia.



Yellow Thistle (Cirsium horridulum)

This species may have cream, pink or maroon flowers. The plants in this area weren’t producing the foot-high flower stalks I’m familiar with at home. The flower stalks were almost non-existent; the plants were producing flowers at ground level. This species is found in many counties in Georgia.



Flowering Dogwood (Cornus florida)

We didn’t see too many Flowering Dogwoods in the WMA. This tree was in full bloom at the edge of the woods not far from the lake. This species may be found in counties throughout Georgia.




I didn’t expect to find as many wildflowers in bloom in this area so it was a pleasant surprise to find so many plants in bloom.

First Angularfruit Milkvine (Matelea gonocarpos) Flowers Of The Season

May 5th, 2012. After we’d completed our run from Saxon to Broad yesterday, we headed down to Clark Hill Wildlife Management Area in McDuffie County to look for wildflowers in general and for milkvines (Matelea sp.). We didn’t see many on our run to the end of the road, but spotted a number on the way back out. The leaves on one of the vines we saw had slightly ‘frilled’ margin (which I forgot to photograph) so I walked over to take a closer look. The vines were matelea vines and as I looked more closely I spotted…

a cluster of buds. The buds of the Angularfruit Milkvine are glossy and concave in profile compared with those of the…

Maroon Carolina Milkvine (Matelea carolinensis). It’s easy to identify Angularfruit Milkvine plants in this area when buds begin to develop.

Clusters of flowers. We have always found green flowers with purple centers. In some areas, flowers are green with no purple color.

have a glossy surface.

Matelea gonocarpos seed pod. If a flower is pollinated, a seed pod will develop in 4 to 5 months.

The seed pod gradually develops a wrinkled surface as the seeds ripen

A ripe seed pod has split open to release seeds.

The seeds - enlarged many times here – are about ¼-inch in diameter.

An empty seed pod we spotted in the Piedmont National Wildlife Refuge in April. The ribs of the angularfruit pod are clearly visible. It’s easy to distinguish these pods from the spiny pods of milkvines like the Maroon Carolina Milkweed (Matelea carolinensis).

Matelea gonocarpos is known as the Angularfruit Milkvine or Eastern Anglepod. It is native to the United States where it may be found from Maryland to Illinois, west to Kansas and south to Texas. In Georgia, it has been documented in several counties not including Greene or Jones counties where we have found it; it occurs in several sites in the Piedmont NWR.

The Integrated Taxonomic Information System (ITIS) lists Matelea gonocarpos and Matelea gonocarpa as accepted names but lists Matelea gonocarpos with the common name Angularfruit Milkvine. Both names appear in different plant lists.

White Crownbeard (Verbesina virginica)

September 4, 2011. We saw a ‘new’ white wildflower as we drove from McDuffie County into Wilkes County. At first there were only small plants with buds but then we encountered a large stand by the roadside. This is Verbesina virginica - known by the common names White Crownbeard, Common Frostweed, Tickweed, Iceplant, Iceweed, Virginia Crownbeard, Indian Tobacco, Richweed, Squawweed. During our trip, we saw it only in the Clarks Hill WMA in Wilkes Country, Georgia.

Verbesina virginica
has two subspecies, virginica and laciniata. The subspecies virginica is distributed more widely – from Pennsylvania west to Iowa and south to Texas - than laciniata which is only found in North and South Carolina, Georgia and Florida. In Georgia, this species is found mainly in the Piedmont and southwest counties as well as a couple of coastal counties. I don’t know which subspecies this plant is.


An interesting note: Verbesina virginica is known as frostweed because after it is exposed to freezing temperatures and still air, liquid water inside the stem freezes and splits the stem open, which then causes water and water vapor inside the stem to emit directly into the air. The water molecules then freeze upon exposure and form delicate ribbons of ice coming from the stem – see a photograph here.

Cutleaf Groundcherry (Physalis angulata)

When I saw this groundcherry plant, I thought I was going to be able to complete a set of photographs of Physalis virginiana (Virginia groundcherry) that I had started taking at Charlie Elliott Wildlife Center in Jasper County, Georgia. When I looked more closely at the plant, however, I found that this was Physalis angulata (Smooth Ground-cherry, Cutleaf Groundcherry, Wild Tomato, Camapu and Winter Cherry).

I found this plant in a bear clearing by the road

The fruit is contained in a calyx that resembles a green Chinese lantern. This fruit is edible.

Physalis angulata is native to the United States. It’s found in states roughly south of a line from Virginia to California. In Georgia, it’s found in counties throughout the state.
