hemispherical operculum and almost entire absence of angularity in calyx or 

 operculum. I proposed the name gracilis for this variety, i.e., JE. calycogona, 

 Turcz., var. gracilis, in Proc. Linn. Soc. N.S.W., 1902, p. 223. 



5. Eucalyptus yilgarnensis, Diels. 



" No. 332, Plantae Australias occidentalis, t. (May), 1901, Yilgarn and Cool- 

 gardie Goldfields in silvis valde apertis, E. Pritzel," is referable to the above variety. 



Doubtful Varieties. 



(c) E. gracilis, F.v.M., var. Thozetiana, F.v.M. {E. Thozetiana, F.v.M.) 



In the " Eucalyptographia " (under U. gracilis) the following passage 

 occurs : — 



Either as a variety, or perhaps even as a species can be distinguished from E. gracilis, an 

 Eucalyptus gathered by the lamented late Monsieur A. Thozet in his last botanical journey to 

 Expedition Range. 



This Eucalyptus, wluch should bear his name, can be distinguished by its longer leaves, narrow - 

 ellipsoid flower-buds, smaller, more or less conspicuously angular calyces and also smaller and particularly 

 narrower fruit, irrespective of the size of the tree, which rises to a height of 60 feet, according to 

 Mr. E. Bowman and Mr. P. O'Shanesy, who noticed it near the Mackenzie and Comet River." 



All the localities mentioned are in Queensland. 

 I have examined specimens from — 

 {a) Expedition Range, Queensland. (M. Thozet, in Herb. Melb.) 

 This is the specimen referred to in the preceding passage. 



(6) " Eucalyptus from the Mackenzie River, Queensland. It sheds all the 

 bark except that on the butt of the trunk." (W. Woolls, who labelled it 

 E. tesselaris.) 



{c) and {d) Warrego and Flinders River, Queensland (F. M. Bailey). The 

 fruits are small, narrow, and sub-cylindrical, but perhaps not perfectly ripe. 



The buds are very narrow and pointed when young ; as they become mature 

 they become plumper, and somewhat resemble those of E. odorata. The leaves are 

 coriaceous and with inconspicuous veins. 



While these specimens probably belong to E. calycogona, in my opinion these 

 Queensland trees appear to show transit to the narrow-leaved forms of E. odorata. 

 Additional material, including ripe fruits, and further particulars as to habit, bark, 

 timber, etc., are necessary before the position of this tree can be stated without 

 doubt. 



{d) For a second doubtful variety, further removed (if a variety) from E. 

 calycogona than E. Thozetiana, see E. ochrophloia, F.v.M., below p. 86.
