LAPSANA

From Botanical Knowledge
Jump to: navigation, search


Lapsana formerly included about 9 species, some from eastern Asia. Based on cladistic analysis of morphologic characters, the eastern Asian species have been removed to Lapasanastrum, a strongly supported monophyletic group characterized by spreading phyllaries and distinctive fruit anatomy (J. H. Pak and K. Bremer 1995).
