May 12th, 2012. Milkworts have been blooming.
Polygala polygama (Racemed Milkwort). The Racemed Milkwort is probably the most widely distributed milkwort in Georgia.
A closer view of individual flowers
Another milkwort that appears to be rare in Georgia is Boykin’s Milkwort (Polygala boykinii). We saw a few plants in bloom beside the Red-cockaded Woodpecker Trail in May 2011. Just a few plants. This year, as we stopped along Starr Road, still in Jasper County, before we reached the Piedmont NWR, W spotted a patch of Boykin’s Milkwort plants beside the road.
A cluster of spikes seen from the truck. It’s easy to see how they might be overlooked.
A little closer, and…
closer still.
The leaves near the top of the spike are clearly alternate but...
are arranged in sets of five near the bottom of the spike.

Closer views of the spike. Individual flowers are between 1/4 to ½ inches across.

Closer views of the flowers. It was windy that day and difficult to get good shots of the individual flowers. These flowers are only about ¼ the size of the flowers of the Racemed Milkwort.
Polygala boykinii (Boykin's milkwort) is native of the United States where it’s found only in Tennessee, Georgia, Florida, Alabama, Mississippi and Louisiana.. In Georgia, it’s only been documented officially in a few counties - Houston, Randolph, Baker, Decatur and Seminole – in southwest Georgia. Our finds in Jasper and Jones counties would place this species two counties north of Houston County.

May 26th, 2012. There’s a tiny granite outcrop by a rural road in Greene County that we visit regularly throughout the year. It’s on our way back from Hancock County. It’s probably not much more than 50’ x 20’ in area but it has some of the essential granite outcrop plants; Appalachian Stitchwort (Minuartia glabra), Elf Orpine (Diamorpha smallii), Grimmia moss, lichen and last, but not least, fairly large areas of Appalachian Fameflower (Phemeranthus teretifolius).
The Appalachian Fameflower is fascinating because flowers don’t open until late afternoon and then only for a few hours. If the flower is not fertilized by a passing insect while it is open, it will self-fertilize. We first saw this plant in bloom at the Rock and Shoals Natural Area near Athens in 2011. The flowers were closed when we arrived at the granite outcrop at 4:30 pm. As we photographed what we thought were buds, the flowers began to open until they were completed open after about 10 minutes.
Then, late last year, we found them at the granite outcrop in Greene County. Last week, we stopped by the outcrop. We couldn’t see the plants from the truck but when we got out, we could see carpets of the succulent leaves that heralded their ‘arrival’ again this year. Yesterday we stopped by again. The flowers weren’t immediately visible but, again, when we walked over to the outcrop we could see that the plants were blooming.
A small area carpeted with the fameflower plants.
A close up of the plant. This is a perennial and the black stub at the base of the succulent leaves is evidence that these plants are several years old.
An individual plant in bloom. The flowers are only about 1/2 inch in diameter.
A couple of flowers.
A single flower in profile. Individual flower stems may have several flowers. Developing buds are visible below the open flower.

This Variegated Fritillary (Euptoieta claudia) was actively working this patch of flowers and probably pollinating it at the same time.
Phemeranthus teretifolius is one of two Phemeranthus sp. that may be found in Georgia and the Carolinas. Phemeranthus teretifolius is known by several common names: Quill Fameflower, Appalachian Rock-pink, Appalachian Fameflower, or Rock Portulaca. Phemeranthus teretifolius is native to the United States: From Pennsylvania, Maryland, West Virginia, Kentucky, Tennessee, the Carolinas, Georgia and Alabama. Phemeranthus teretifolius is distributed more widely in the Piedmont in Georgia than is Phemeranthus mengesii.
