There are so many plants that I may have overlooked because the flowers are very small, green and, it seems, the plants have to be a certain age before they bloom. Smilax rotundifolia (Roundleaf Greenbriar) appears to be another one of these plants. I’ve been looking at the plants round our place for many years. Finally, this year, I saw blooms.
Smilax rotundifolia is known by the common names Roundleaf Greenbrier, Common Greenbrier, Common Catbrier, Bullbrier, or Horsebrier. It’s fairly common in this area. At Fort Yargo State Park it grows along the trail on the right, just past the woods when leaving the bridge from the Section B boat launch (segment 2).
Early in the season, the leaves are not particularly rounded.
By the end of the season the leaves are quite rounded.

Five Uvularia species grow in the Carolinas and Georgia. Based on the leaf shape and the stalked flower arrangement, this plant appears to be either Uvularia grandiflora (Largeflower Bellwort) or Uvularia perfoliata (Perfoliate Bellwort). I didn’t see the flower. However, based on the known geographic disribution of U. grandiflora and U. perfoliata, this species is probably U. perfoliata. So far, I’ve only seen it at Fort Yargo State Park where I saw one plant along the trail on segment 12.
Another plant I almost missed. For a long time I thought the flowers hadn’t developed. I’m inclined to think now that I may have photographed the developing fruit. Can anyone throw any light on this? I’ll have to stalk this plant next Spring and see if I can photograph the bloom.
The plant. It stood about 2 feet high in the woods along the Rock Garden trail.

A little closer still.

Rebecca in the Woods sent me this link to her photos of the U. perfoliata fruit. Thanks Rebecca! This seems to confirm that 'my' fruit didn't develop. A challenge for next year.
The Uvularia species, U. grandiflora and U. perfoliata, are native to the United States and Canada. U. grandiflora has a wider range than U. perfoliata.
U. grandiflora grows in the eastern United States and Canada. In the United States, it grows in states including, and east of North and South Dakota, Iowa, Kansas, Oklahoma and Louisiana; it doesn’t grow in Maine or Florida. In Canada, it grows in Mannitoba, Ontario and Quebec. In Georgia it has only been reported from three counties – Chatooga, Walker, and Floyd - in the far northwest of the state.
U. perfoliata has a more limited range. In the United States, it grows in states including and east of Indiana, Kentucky, Oklahoma and Texas; it does grow in Maine and Florida. In Canada, it grows only in Ontario. In Georgia it has been reported from many counties.
