W.A., 85 miles N.E. by 



Range ; W.A., near Mount Squires, Victoria Desert (C. 54), 

 with glabrous achenes and with a pappus transitory to that of 

 llelipterum. 



Helicheysum ambiguum, Titrcz. S.A., Arkaringa Creek, 

 Everard Range. W.A., near Barrow Range, with narrower more 

 ciliolated involucral bracts; Victoria Desert (C. 50), Eraser 

 Range. 



Helichrysum APicuLATDM, De Cand. S.A., Warrina to 

 Everard Range; W.A., near Mount Ilbillee soakage, Eraser 

 Range. 



Helichrysum Ayersii, /'. v. M. S.A., towards Everard Range; 

 W.A., near Mount Squires. 



Helichrysum adsatum, BentJmm. 

 E. from E.sperance Bay (Gwynne). 



Headlets in an unopened state almost globular, or verging into 

 an ovate-ellipsoid form as also in H. lepidophyllum ; but like- 

 wise probably when fully developed campanular-hemiellipsoid. 

 The latter species, however, has its leaves always bent downvv'ard, 

 never erect ; they are moreover usually shorter and always pro- 

 portionately much broader. In the Elder-Expedition plant the 

 leaves are adnate at and near the median line of upper side to 

 their middle or even beyond, towards the margin free. It 

 differs mainly from H. diotopkyUum in having the leaves more 

 adnate, and not conspicuously and suddenly dilated at and near 

 the base and in having the floral bracts not yellowish. It is 

 distinct from the genuine H. decurrens in, though adnate, yet 

 not really decurrent leaves, which have an acute apex. From 

 fl. retusum it is removed by the form of the leaves and the color 

 of the flower-headlets.
