Crataegus castlegarensis occurs from around the northern Okanagan, British Columbia, to the northern California Coast Ranges, to northwestern Montana, and the Rocky Mountains to northeast of Salt Lake City, Utah. The species occurs also in the Cypress Hills of Alberta and Saskatchewan; it is found in habitats similar to those of C. douglasii and is at least as abundant as that species in a number of parts of its range. Crataegus castlegarensis is readily recognized by a combination of hairy inflorescence branches, pomes more or less orbicular, crimson or burgundy (with irregular earlier ripening) around the third week of August, soon becoming purple, often when nearby C. douglasii is already black, as well as a tendency to possess thorns on the young twigs branched at the base to become double, triple, or even sometimes quadruple. Such multiple thorns, though sometimes abundant on a bush, are more often few and may require searching for. Inflorescence pubescence, as in other species with this characteristic, may become sparse by fruiting. Crataegus castlegarensis is most similar to C. douglasii; its fruit is usually more orbicular, even oblately so, than is normal in that species, sometimes even with a recessed junction to the pedicel like an apple.

Most specimens of Crataegus leonensis are from Leon County, Florida, but a few come from southern Georgia. Crataegus leonensis is most similar to C. mira, of which it may prove to be an extreme form; it has smaller flowers and differently shaped, narrower leaves. An unnamed entity from northern Florida and southeastern Alabama to North Carolina, which could key to C. leonensis, is held to be closer to C. annosa. It differs from C. leonensis by larger leaves (3–5 cm) and fruit (12–15 mm), somewhat different leaf shape (broadly elliptic to rhombic, sharply lobed), always dense inflorescence indumentum, and cream anthers. Crataegus subflavida Murrill may be synonymous but has larger yellow pomes. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
