  • Discussion

    This has gone under the name of D. incana, but the latter is much less densely stellate and has a glabrous, much broader pod. I have seen only one specimen of true D. incana from this continent, and it was collected in Labrador. Most of those under this name belong to D. cana, which ranges from Labrador to the Yukon Territory, south in the mountains to Colorado. The following is regarded as the type.
