Bidens vulgata Greene. (North America.) The specimens in New Zealand herbaria under the name of B. tripartitus Linn., a European species, have been wrongly determined and actually belong to B. vulgata Greene. Our plant differs markedly in leaf and achene characters from B. tripartitus Linn., and the name therefore requires to be expunged.
