Discussion

Varieties 5 (5 in the flora).

Crataegus succulenta ranges through the southern Great Lakes area to the middle St. Lawrence and southern New England, to Minnesota, to Iowa, Missouri (very rare), and Ohio, the Appalachians to North Carolina. An outlier has recently been recognized in Manitoba.

The dark twig colors of Crataegus succulenta are dramatic in winter and the coral red expanding bud scales are conspicuous in spring, more so than in most other species of hawthorn except C. macracantha. In summer, its commonly bluish green leaves, eglandular petioles, and impressed venation combine with thorn and twig characteristics to make this and C. macracantha usually instantly recognizable.

Crataegus succulenta often forms suckering thickets in the north.

Varieties 9 (9 in the flora).

Crataegus chrysocarpa is one of the most wide-ranging North American species of the genus, occurring from inland of the Cascades and Coastal Ranges of Oregon, Washington, and British Columbia to the Atlantic from Newfoundland to New England; it is correspondingly variable. Ashe’s type from the Rocky Mountain foothills in northern Colorado is from the south of the range. East of the Rocky Mountains, C. chrysocarpa is the most northerly and cold-adapted species of hawthorn in North America and nearly reaches Hudson Bay in Ontario. Rare northeastern forms are arborescent (to 70 dm).

Variety chrysocarpa is by far the most common form through most of the species range; numerous well-marked to only slightly different forms, many accepted here at varietal level, occur in different parts of the range. The main regional variant is var. piperi, a well-marked intermontane form.

One to two year old twigs of var. chrysocarpa are much darker in the east (reddish tan or darker) than in the west (light tan to gray-brown).
