August 4th,
2012. I’m familiar with Aureolaria flava, the Smooth Yellow False Foxglove, which grows at Fort Yargo State Park. So when I saw
aureolarias blooming in the Oconee National Forest, I didn’t take much notice. And then I
saw a particularly pretty plant and decided to take a closer look.
It was
Aureloaria pectinata, the Combleaf Yellow False Foxglove. Compared with
Aureolaria flava which has opaque petals, Aureolaria pectinata has slightly
translucent petals. The flowers and
stems, and leaves have sticky glandular hairs as I found out when I moved a
stem to get a better view – hence the specific name ‘pectinata.’
The flower
The leaf.
Leaves are opposite and have a distinctly incised margins – giving the
plant the ‘combleaf’ name.
A bud which clearly shows the hairs.
A close up of the hairs clearly showing small
droplets of propolis. I didn't shoot this photo deliberately. I just notices the droplets in the previous photo and cropped it to highlight these. In fact, I'd forgotten that the plant was sticky until I saw this photograph.

Views of the flower to show the stamen and
stigma. The relative translucency of the petals and the veining are clearly
visible.
Aureolaria pectinata (Combleaf Yellow False
Foxglove, Southern Oak-leach) is native of the
United States where it’s found in states southeast of a line from Virginia to Missouri
and southwest to Oklahoma and Texas. In Georgia, it’s found in many counties
throughout the state. It has not been documented in Greene County or Oglethorpe
County.
