or less ribbed, about 4 mm. in diameter. Anthers ovate-emarginate, opening in longi- 

 tudinal slits, with a prominent dorsal gland. Floral disc forming a thin, dark carnose 

 lining around the calyx-tube, and extending for a short distance over the top of the 

 ovary, which is much paler in colour. 



Fruit pyriform to cylindrical, truncate, gradually diminishing into the short, 

 thick pedicel; 10 mm. long, 6 mm. broad, the rim sharp and sloping inwards, 4-celled, 

 the valves rather short, all enclosed. Capsular disc forming with the staminal ring 

 a slightly thickened oblique band around the inner rim of the calyx -tube; staminal ring 

 present. Seeds not seen. 



RANGE. 



It has only been seen at Dongarra, in Western Australia, up to the present. 

 Dongarra is a railway station on the coast, 275 miles north of Fremantle, and 43 miles 

 south of Geraldton. 



In Part XXXVIII, p. 222, under E. dumosa, I made the following statement 

 from my notebook, made in 1909, when standing in front of the trees :— " At Dongarra, 

 not far from the beach, is a dense growth of slender white gums, ribbony at butt, 

 which reminds one of dense Mallee, but not true Mallee, 20-25 feet high, trunk 4 inches 

 diameter. Wood very tough, a little brown at heart. Operculum a little ribbed. 

 Broad, coarse suckers; glaucous buds. It is very close to the typical incrassata, 

 certainly a connecting link." 



AFFINITIES. 



1. With E. dumosa A. Cunn. See Part XXXVIII, p. 220. 



It seems to be more of a white gum than E. dumosa, and perhaps a somewhat 

 larger type of mallee, but this is not certain. It is also more glaucous, especially in the 

 juvenile leaves and buds. The operculum is also shorter and the fruit larger and more 

 pyriform. 



2. With E. eonglobata (R.Br.) Maiden. See Part IV, p. 100, also Part LVI, 



p. 274. 



It seems to resemble E. eonglobata in its mallee-like habit, but the stems are 

 straighter and whiter. The juvenile leaves of both species are glaucous, but those of 

 E. Dongarraensis are considerably coarser. In buds and fruits both species are easily 

 separated. 



3. With E. incrassata Labill, vide Part IT, p. 93. 



The juvenile leaves and the anthers of E. incrassata and E. Dongarraensis are 

 somewhat similar, and they appear to be the only botanical characters upon which 

 an affinity can be based. The juvenile leaves are, however, much broader and more 

 glaucous than those of E. incrassata.
