Shrubs, 60 dm, branches strongly weeping (moving in slight wind). Stems: trunk bark dark brown, rimose; twigs: new growth pubescent, 1–2-years old dark purple-brown, slender; thorns on twigs ± straight, 1–2-years old dark purple-brown, fine, 2 cm.

Discussion
Crataegus floridana is frequent in north-central Florida and extends through much of Georgia with single records from Kershaw County, South Carolina, and Brunswick County, North Carolina.
Crataegus floridana resembles C. quaesita in its more or less obtrullate, but distally lobed leaves (which can always be observed fluttering in the wind) and longer petioles. The largest leaves in subser. Tenues may be found in Crataegus floridana; there is considerable size variation. The depth and sharpness of the lobes is variable, with a maximum in the proportionately broadest leaves, these having been called C. anisophylla. Differences from 146. C. meridiana are noted there.
