* Sparganium angustifolium ‘Michx., an American plant, takes precedence of 8. 
angustifolium R.Br., therefore R. Brown’s name is untenable for the Australian plant. 
(Engler’s Pflanzenreich iv, 10, Sparganiacex, p. 19, 1900.) Prof. Rothert, who 
examined all the Sydney herbarium Australian Sparganiums in 1909, thinks the New 
South Wales species is identical with 9. stenophyllwm Maxim, an Asiatic species. 
{Z. nana. Roth. (B.FI. vii, 176) is not an Australian plant, according to Ascherson and 
Graebner’s Monograph of Potamogetonacex (1907) ; it is probably a wrong determination 
of one of the two New South Wales species.
