A new and rare species of Nymphoides (Menyanthaceae) from the North West of Western Australia
DAVIS, R.W., HAMMER, T.A. AND THIELE, K.R.
Nymphoides walshiae R.W.Davis & K.R.Thiele, a new and rare species of Nymphoides Ség., is described. This new species is geographically disjunct from other Nymphoides species, occurring in a small area of arid Western Australia near the Cape Range. A molecular phylogenetic analysis based on ITS sequences suggests that it occupies a phylogenetically isolated position sister to the largest clade in the genus. It lacks some of the more common features seen in the genus Nymphoides. A scanning electron microscope image displaying the seed surface and outline is provided.
