Editorial Note
Since the publication of Bean the seven species constituting Penstemon subgen. Hesperothamnus (Keck) Keck – mainly chaparral shrubs with a tendency to very woody stems – have been referred to the segregate genus Keckiella Straw. The two genera are distinguished by nectary structure (glandular hairs on the stamens in Penstemon, while Keckiella has nectariferous hypogynous discs) and by the attachment of the fertile stamens on the corolla (at two levels in Penstemon, a single level in Keckiella) (Straw 1966, Flora of North America 2025). A fuller, revised treatment of this genus will be provided when funding is available. If you would like to sponsor the work please write to editor@treesandshrubsonline.org
