DESCRIPTION. 



CXX. E. cassia Benth. 



In B.E1. iii, 227 (1SGG), winch need not be transcribed. 



The type is Drummond's 5th Collection, Supplements No. 3G. 



It is not figured in the " Eucalyptographia." It is a tree of 2C-30 feet. 



Mueller and Tate, in describing the plants of the Elder Expedition, supple- 

 ment our knowledge of this species in the following manner : — 



Some of the leaves verge into a lanceolar-ovate form. Flowers (hitherto undescribed) when 

 expanding, sometimes less than a quarter inch long ; calyces just before opening measuring in total length 

 from two-thirds to one inch; tube turbinate-semiovate, often dilated near its edge, somewhat striate; 

 operculum about as long as the tube, hemispheric, suddenly terminating into a conspicuous narrow conic 

 protraction; stamens inflected while in bud, all fertile; filaments rigidulous, dull-yellowish when dried, 

 some attaining a length rather above half an inch ; anthers pale, cuneate-ellipsoid, broader towards the 

 base but pendent, bursting by longitudinal fissures ; style prominent, but considerably shorter than the 

 stamens ; stigma hardly broader than the summit of the style. (Troc. Roy. Soc. S.A., xvi, 358.) 



The roots of this Eucalypt, termed " Gungurru," are eaten. (Helms, op. 

 elf., p. 325.) 



RANGE. 



The species is confined to Western Australia. 



The type is stated to have come from the Murchison River. 



Mueller records it from Victoria Desert (No. C. G3), 40 miles north-west from 

 Eraser Range (R. Helms, Elder Expedition) ; also from Mount Stirling, and about 

 50 miles east from York (Hon. W. M. Parker). See Proc. B. S., S.A., xvi, 353. 

 The two last localities remove it from the desert to no great distance east of both 

 York and Albany, and all three localities are a good deal distant from the Murchison. 



AFFINITIES. 



1. With E. incrassata Labill. 



" The examination of the flowers now shows that this species should take its 

 systematic place near E. incrassata " (Mueller and Tate loc. cit.). I have only 

 seen Drummond's specimen of indubitable casia. Mueller's material may be my
