| | Site: Blue Hole Area, Pigeon Mountain, Walker County, GA Date: 2010-April-18 | Photographer: Gerald C. Williamson | | Some say that the leaf of Cynoglossum looks like a hounds tongue, giving the genus its name. The blossom is pale blue, so pale that it may be difficult to detect any blue in the flower at all, especially in the shaded forests where they often grow. | |

Nikon D40 | | The blossom of Cynoglossum virginianum var. virginianum, the variety on this page, has 5 pale blue rounded lobes which may overlap somewhat. The corolla lobes of var. boreale (Northern Hounds-tongue) are smaller, oblong, and do not overlap. Some authorities classify var. boreale as a separate species - Cynoglossum boreale. | | Click on the photo for a larger image
