Discussion
Of conservation concern.
Variety sordida is rare in southern Missouri.
B. F. Bush noted on a herbarium label that var. sordida flowered later and had larger flowers than sympatric Crataegus collina, assumed to be var. collina. The bracteoles of var. sordida are particularly narrow (20:1). Variety sordida has not been recorded since the early 1900s.
