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.

Crataegus dispar is a somewhat scarce species, concentrated in South Carolina and with scattered records from Alabama, Florida, and Georgia. The author notes the species in South Carolina grows in extremely dry conditions. Crataegus dispar is one of the most easily recognized members of ser. Lacrimatae, even identifiable in specimens lacking reproductive parts and sometimes from extension shoots alone. Of note are the wide extension-shoot leaves, often deeply incised into wide-spreading, sharp segments lobed nearly to the sinuses, rather as in C. marshallii.
