Discussion
Crataegus intricata ranges in Appalachia from southern New England to Georgia and Alabama. The distribution given above, relative to similar taxa, may be somewhat over-represented because the species has been the default identification for doubtful (particularly fruiting) material of much ser. Intricatae with glabrous leaves and inflorescences.
Crataegus intricata is the common, widespread member of this series with lobed leaves, ten stamens, white or cream anthers, and glabrous inflorescences. Depth and sharpness of lobes and location of widest part of leaf are somewhat variable, as is plant stature, some forms appearing mature at 1–2 m.
W. W. Eggleston collected a distinctive form in the Crataegus intricata complex in September 1908 from North Carolina, in which the short-shoot leaves are broadly ovate to deltate with shallow obtuse lobes. This has a printed label naming it C. virgata Ashe. Though type material of C. virgata could not be located, the protologue by Ashe could fit. It is possible that all the southeastern forms from the intricata complex with shallow and obtuse lobes, proportionately wide leaves, and cream anthers represent C. virgata.
