Ceratophyllum demersum L.[FNA3, HC, HC2]
coon's-tail

Publication: Sp. Pl. 2: 992. 1753.

Origin: Native

selected vouchers: WTU

Notes: FNA3: "Specimens of Ceratophyllum demersum with short basal spines or tubercles have been misidentified as C . submersum Linnaeus, a species not known in the New World despite reports to the contrary. Ceratophyllum demersum is the most common species of Ceratophyllum in North America and also the least likely to be found with fruit, its reproduction being primarily asexual. Predominantly low leaf order is, therefore, the most reliable means of identifying this species.

Noted for its prolific growth, Ceratophyllum demersum occasionally has attained status as a serious weed."
