Road Trip: Oglethorpe –Wilkes Counties, July 28th, 2015 (Part 1)


July 28th. Most of our trips over to Wilkes County, Georgia, have coincided with frog surveillance trips; these trips were finished for the year but we decided to make a trip just to look at wildflowers. 


The first part of the trip was from GA-77 in Oglethorpe County to GA-17 in Wilkes County on the Saxon Mattox (Oglethorpe County) – CR113 (Wilkes County) road. This is an unpaved road that may be slippery after rain. Since it had been dry for a while, we thought it would be interesting to take this route, rather than the main highway, to Wilkes County. 

In the past, we’ve found a variety of wildflowers along this road including many Carolina Milkvines (Matelea carolinensis) vines. Unfortunately, contractors had been clearing under the power lines along this road so many of the wildflowers we expected to see, including the Carolina Milkvines, were not blooming. We did, however, see a number of wildflowers or fruits of interest.


The first sighting was a Partidge Pea (Chamaecrista fasciculata) plant growing at the edge of the road. It was one of the few of these plants we saw. Usually the roadside is lined with these plants.


We did find matelea vines; the tell-tale pairs of large, heart-shaped leaves gave them away. But they were…


the Angularfruit MIlkvine (Matelea gonocarpos). The amazing finding was a cluster of three large seedpods from one cluster of flowers. I’m used to seeing one pod on a vine but to find three was outstanding. 

As I was making my way along the embankment to check another vine (that didn’t have any pods), I had to step over a vine and there, at knee height, was a…


small, cute pod. I wonder if it will develop to maturity; it was way behind the others in development. 

Across the road, I spotted a leaf that I recognized immediately. A…


Yellow Passionflower (Passiflora lutea). Unfortunately, the vine wasn’t blooming, but it was healthy. It will be interesting to check this vine out earlier in the season. These are beautiful little flowers and worthwhile searching out. 


Below it was a Dodder (Cuscuta sp.) plant in bloom. 

A little further along the road, I spotted a few...


Allegheny Monkeyflower (Mimulus ringens) flowers. The plants were growing in a roadside ditch and were only a couple of feet high – small compared with the six-foot high plants near our creek.


A Spurred Butterflypea (Centrosema virginianum) vine had climbed up a tree beside the road and was blooming profusely. Many of the flowers were above head height.


Skippers were enjoying feeding on the flowers. 

I was delighted to find an…


Eastern Hophornbeam (Ostrya virginiana) blooming at the side of the road. 

One of the most exciting sightings along this road was a…


Smallflower Pawpaw (Asimina parviflora) growing on the roadside embankment. I spotted it and asked W to back up to take a closer look. When we stopped, I could see the…


fruit before I got out of the car.


This plant had quite a number of fruit; five alone on one branch. They weren’t ripe and I expect the local wildlife will get to the fruit first when they do ripen.


I’ve seen Rosepink (Sabatia angularis) in several locations but this was the first time I had seen them…


developing seed capsules.


Toward the end of this section of road, we passed a field with some sheep. At first, it looked they had been shorn but then I noticed that…


some of them still had wool attached. These sheep were ‘self-shearing’ sheep that were shedding their wool naturally. 

The final sighting on this section of road was…


Perennial Wildbean (Strophostyles umbellata) that were blooming in the hedgerows by the road. 

In spite of the clearing of the roadside, we had some nice spottings on this road. From here, we continued onto our ‘regular’ route in Wilkes County.

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…

Buds. Maroon Carolina Milkvine (Matelea carolinensis)

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.

A closer view of one of the flowers. These flowers have a matte surface. Newly opened flowers we have found in Greene County…

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.
