Following is the description : — 



Mallee patens oirciter 6' alta; primariis foliis non visis, niaturis foliis pallido- (glauco-) viridibus, 

 crassissimis, petiolatis, late lanceolatis ad fere ovatis circiter 5 cm. maxima latitudine, in acumen obtusum 

 attenuatis, venis obscuriusculis, vena peripherica a margine longe remota, venis lateralibus angulum circiter 

 30-45° costa media formantibus ; inflorescentia a.xillari, alabastris non visis ; floribus in pedunculis longis fere 

 teretibus, umbellis ad 7 floris in pedicellis brevioribus, stylo longissimo; fructibus in pedicellis brevibus 

 distinctis teretibus, junioribus campanulatis, maturis piriformibus, magnis, circiter 2 cm. longis, promineuter 

 costatis valvarum verticibus distincte depressis. 



A small, shrubby Mallee. about 6 feet high, and spreading 6-8 feet, branchlets terete or nearly so. 



Juvenile leaves not seen. 



Mature leaves pale -(glaucous-) green, apparently the same colour on both sides, very thick, 

 alternate, petiolate, broadly lanceolate to nearly ovate, with greatest width of about 5 cm. and length of 

 12 cm. and more, tapering into a blunt point, venation not very distinct; intramarginal veins well removed 

 from the edge, the lateral veins spreading and at an angle of about 30-45 degrees with the midrib. The 

 petioles, midribs and marginal vein yellowish. 



Inflorescence axillary, buds not seen, flowers on long, nearly terete peduncles, bearing umbels 

 with up to seven in the head on shorter, but distinct, nearly terete pedicels, a style remarkably protruding 

 beyond the stamens (pointing to rather a long operculum) for about the length of the calyx-tube, not capitate ; 

 anthers large, broad, opening in parallel slits, gland at back. 



Fruits on short but distinct, terete pedicels, when young distinctly urceolate or campanulate, 

 when ripe, somewhat decumbent, pear-shaped, large, about 2 cm. long at 1-5 cm. in greatest diameter, 

 distinctly yet not prominently and branchingly ribbed, narrower at the orifice, the narrow rim darker in 

 colour, and the tips of the valves distinctly sunk. 



Type, Ernest H. Ising, 407 miles, near Ooldea, South Australia, No. 1480, 5th 

 September, 1920. 



RANGE. 



At 407 miles (from Port Augusta), near Ooldea, on the Transcontinental Railway. 

 " In whitish, sandy soil, between sandhills." This locality is in South Australia (not 

 far from the Great Australian Bight), and it may be confidently predicted that the 

 species will be found, later on, in Western Austrab'a.
