Discussion

Ctenolepis cerasiformis was collected by C. F. Reed in 1958 at temporary unloading sites for chrome ore from cargo ships in the Port of Baltimore. The plants are distinctive in their annual duration, deeply lobed leaves, foliaceous stipuliform bracts with stiffly ciliate margins, tiny white flowers, and small, few-seeded, smooth, red, berrylike fruits on relatively short peduncles.
