4. E. graphitinum {F. v. M. and Tate), Ewart and Cookson. Plate VI. — 

 A small glabrous herb with tufted leaves and small fibrous root, plants varying 

 in size, when in flower from 3 to 13.2 cms. Leaves radical, sessile, linear .5 to 

 1.8 cms. long, and .1 to .4 cms. wide, tapering to a short, sharp point. Scapes 

 slender, twisted 2 to 12 cms. long. Flower heads glabrous, globular. Long 

 fine hairs arise from the elongated receptacle, between the flowers, but are not 

 seen on the outer surface of the head. Outer empty bracts thin and oblong. 

 Flowering bracts linear-spathulate, with a blunt point. 



Male Flower. Outer perianth segments 3, linear with an obtuse apex 

 inserted near the base of the flower stalk. Inner perianth segments none, 

 represented by 3 small black glands at centre of flower. Stamens 6, anthers 

 large, dehiscing longitudinally. 



Female flower. Outer perianth segments 3, somewhat acuminate. Irmer 

 segments 3, narrow-linear longer than segments of outer perianth with a few 

 short hair-like outgrowths from the obtuse apex. Ovary consists of 3, 1-seeded 

 carpels which open by two valves when seeds are ripe. Style single with 3 long 

 stigmas. 



Collected in 1889 by Col. Tietkens from west end of MacdonneU Ranges, 

 and also from 12 miles from McKinley River. Named by Baron von Mueller 

 and Professor Tate, who recorded it as a new species in Trans. Roy. Soc, S.A., 

 Vol. XIIL, 1890, and Vol. XIX., 1895, and in Report of Horn Exped., III. 

 No description was given and plant was recorded as a nomzn nudum in Kew 

 Index. Additional material was supplied by Professor Osborne from the 

 Adelaide Herbarium, and it has actually proved to be a valid species, hence the 

 above description has been made with figures illustrating its structure which 

 appear on Plate VI. 



5. E. lividum, F. v. M. — York Sound, A. Cunningham ; near M'Adam 

 Range, F. v. Mueller. 



6. E. monoscapum, F. v. M. — Margins of water-courses towards M'Adam 

 Range, F. v. Mueller. 



7. E. nigricans, B. Br. — Carron Creek, Carpentaria, Gulliver.
