E. ovata Nees var. nana Sp. Moore in Journ. Linn. Soc. XXXIV. 229? 
Hab. in distr. Coolgardie pr. Bullabulling in silvis apertis lapidoso- 
lutosis fruct. m. Oct. (D. 5949). 
Ab E. Preissiana differt habitu, inflorescentia pauciflora; glumis latioribus obtusis, 
gluma florifera parte inferiore longe hirsuto-villosa. Æ. ovata Nees in Hook. Lond. 
Journ. Bot. Il. 446 quacum DBENTHAM Fl. Austr. VIL 630 E. Preissianam conjunxit e 
descriptione nimis brevi non certe intelligi potest; sed spiculo unico e herbario Neesiano 
museo Berolinensi communicato examinato eam ab E. Preissiana abhorrere persuasum 
habeo. Quae cum ita sint, species 3 in Australia occidentali indigenae atque arclius 
affines nobis accipiendas esse videtur.
