Crataegus flabellata occurs along the Niagara Escarpment in Ontario, on both sides of Lake Ontario and the St. Lawrence, to New Brunswick and Nova Scotia, and to Massachusetts. Reports for Newfoundland have not been substantiated. Crataegus flabellata is distinctive with its leaf blades glossy dark green, ovate to broadly elliptic, cuneate at the base, and with deep acuminate lobes. Specimens with less glandularity or serration of the sepal margins may resemble C. fluviatilis. In spite of the obvious differences in morphology and range, C. flabellata and C. macrosperma often have been combined by floristicians. From C. chrysocarpa, C. flabellata is distinguished by its shinier, ellipsoid, glabrous fruit, by the usually deeper, acuminate lobes of its glossy, dark green leaves, and by longer, slightly more acute sepals. Typically, the inflorescences and hypanthia of eastern C. chrysocarpa are densely hairy, practically tomentose, unlike C. flabellata with its more sparsely hairy pedicels and glabrous distal hypanthia. It is conceivable that, due to morphological intermediacy and the sympatry of all three species within the range of C. flabellata, this species represents the result of ancient hybridization between C. chrysocarpa and C. macrosperma. Crataegus flabellata is usually divided into two varieties: var. flabellata (10 stamens) and var. grayana (20 stamens), the latter being particularly common in southern Quebec. There appears to be little, if any, other constant differentiating feature. Crataegus crudelis, also from Quebec, is a form recognized by long thorns (to 10 cm). The name Crataegus densiflora Sargent, which pertains to C. flabellata, is illegitimate. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Crataegus lacrimata is found abundantly over parts of the Florida panhandle and through adjacent Alabama and Georgia to South Carolina. Crataegus lacrimata is an upright, usually single-stemmed shrub with slender, more or less weeping branches and small, narrow, glabrous, bright green leaves. The plants are easily recognized among ser. Lacrimatae, the whole plant being almost completely glabrous, having narrow, nearly unlobed leaves, and being the only member of the series to possess more or less eglandular bracteoles. Only with poor material might the pubescent inflorescence of C. munda (dwarf, non-lacrimate) or C. crocea (tall, lacrimate) be confused. A form similar to C. lacrimata and with the same range, but apparently discontinuously larger, has longer leaves (blades 2.2–4 cm versus 1–1.7 cm) and larger flowers (petals 7–9 mm versus 5–7 mm) and more orange-colored ripe fruit.
