10a. Enlarged ; dorsal view, showing the very thin circumferential wing. The wing of this species appears 



to be of a more delicate texture than any other species. 

 106. Enlarged : ventral view showing the small hilum in the centre of the endosperm and the net-like 



ridges or rudimentary wings almost surrounding it, and which connect with the circumferential 



wing. 

 10c. Enlarged ; dorsal view of a very thin seed, showing the delicate nature of the wing, which is so thin 



that a very slight pressure causes it to roll over. Note also the four faint ridges on the back. 

 lOd. Enlarged ; dorsal view of another seed, showing the expanded, undulate, circumferential wing, with 



an inner rudimentary wing on the back of the endosperm. Coastal South- West Australia (D. A. 



Herbert). 



Series Curviptera. 



11. E. EuruKoppinensis n.sp., natural size. 



11a. Enlarged; vertical position of seed, showing the nerve-like wings on the side and the smooth space 



between them. 

 116. Enlarged, showing a quadrangular seed, with longitudinal ridges, which end in a short curved wing, 

 lie. Enlarged, showing twin seeds, with a very narrow circumferential rudimentary wing. 

 lid. Enlarged ; a triangular seed, showing the hilum and the curved wing, 

 lie. Enlarged; another view of lid. 

 11/. Enlarged; a more D-shaped seed, showing the confluent rudimentary wing, lateral wing, and the 



curved terminal wing, also a faint line down the centre of the seed. 

 llg. Enlarged; a somewhat triangular seed, with the small curved terminal wing and two sharp lateral 



ridges. Burracoppin, 192 miles east of Perth, Western Australia (Forester F. M. C. Schock, July, 



1917). 



PLATE 259. 



Series Micromembranese. 



1. E. Lehntanni Preiss, natural size. Black seeds, with slight evidence of membranous edge. 



la. Enlarged; ventral view, showing the small hilum and the very faint radiating ridges, and also the 



membranous margin. 

 16. Enlarged; ventral view of a more uniform seed, showing the obscure hilum and the slightly raisad 



radiating ridges, also the circumferential membrane. 

 le. Enlarged; ventral view of a more triangular seed, with a prominent hilum and stronger nerves. It 



is much thicker than la and 16. 

 Id. Enlarged ; dorsal view of a more orbicular seed, showing the slightly convex back and the marginal 



membrane, 

 le. Enlarged; ventral view of a very compressed seed, showing the depressed hilum. It is abruptly 



truncate at one end, while the opposite end is expanded for a short distance into a thin membrane.. 



Cultivated (?) near Albany, Western Australia (J. Wellstead, January, 1920). 



2. E. comuta Labill., natural size. 



2a. Enlarged ; ventral view of a somewhat triangular seed, showing the small hilum and a slightly toothedi 



margin. 

 26. Enlarged ; ventral view of an ovate seed, which is obliquely truncate at one end. 

 2c. Enlarged; ventral view of an oblong seed. 

 2d. Enlarged ; ventral view of an orbicular seed. 



2e. Enlarged ; ventral view of an orbicular seed, showing slight radiating ridges. 

 2/. Enlarged; dorsal view of a seed showing the smooth back. King George's Sound, South- West Australia; 



(C. E. Lane-Poole, September, 1915). 



3. E. occidentalis Endl., natural size, with slight indications of a ragged membranous edge. 



3a. Enlarged; ventral view of a somewhat ovate seed, showing the large hilum and the faint^ radiating; 

 ridges, also a thin membrane.
