Shrubs or trees, 20–50 dm, branches ± weeping. Stems: trunk bark ashy gray, rough or scaly; twigs: new growth densely white-canescent, 1-year old purple-brown or blackish, older dark gray; thorns on twigs absent or rare, straight or slightly recurved, 1-year old blackish or purple-brown, ± stout, 3–4.5 cm.

Discussion
Crataegus lassa is particularly abundant around its type locality of Selma, Alabama. The species normally has big, floppy leaves. The type material has rather shorter leaves than most specimens seen commonly near Selma today and is notable for having a few small terminal lobes. Crataegus illudens is barely different but has somewhat longer leaves and leaf tips more often entire. Crataegus panda is a form with a slightly shorter and relatively wider leaf, minutely crenate on the margins; also see the discussion under 144. C. lanata.
