Parietaria praetermissa Hinton

Parietaria praetermissa is an annual, trailing herb up to 55 cm (22 inches) tall. Leaves are ovate or lanceolate, up to 6.5 cm (2.6 inches) long.^[3][4][5]

According to Hinton,^[3] Parietaria praetermissa was for many years erroneous called Parietaria floridana. However, when Hinton examined the type specimen of P. floridana, he discovered that it was a different species, the only that had been called Parietaria nummularia. Under the rules of botanical nomenclature, this meant that P. nummularia needed to be renamed P. floridana, and the species that had long been called P. floridana was in fact an undescribed species, one which Hinton described as P. praetermissa.
