| Distribution | Collected in Madison, Forsyth, Mecklenburg, and Durham counties. A specimen from Wake County needs an ID check; it appears to be Linaria canadensis.
Native of Eurasia; in N.A. essentially throughout Canada and the U.S., except the Southwest. | |
| Abundance | Very rare. Individual populations, such as the one(s) in Durham County, can be very large. | |
| Habitat | Railroad edges on diabase sill, other railroad edges -- there are several collections in Durham County from such sites. The Forsyth and Madison county records do not have label data available. | |
| Phenology | Flowering and fruiting May-October. | |
| Identification | Dwarf Snapdragon is a glandular-pubescent, branched annual up to a foot tall (but usually much less). The leaves are mostly alternate, linear-elliptic, reaching at most only 2 cm long. The flowers grow singly in leaf axils, whitish to more often light lavender blue, with a yellow throat. There are 2 upper petals and 3 lower, one of which has a short, backward-pointing spur. It may be confused with Canada Toadflax (Linaria canadensis), but that plant is taller, unbranched, the leaves linear, and has a prostrate basal rosette of leafy branches. | |
