masses.] H. Troedelii,~F. v M. Murteree ; Strzelecki Creek; 

 Mount Lyndhurst. Heads 12-22-flowered ; pappus-bristles 

 8-10, united in the lower half; stems erect, but varying much 

 in height, those from Strzelecki Creek 22 cm. high, those from 

 Mount Lyndhurst only 6-9 cm. [Found throughout the 

 country traversed, and in many places it grew in compact 

 masses.] H. eorymbiflorvm, Schlecht. Sandhills 15 miles west 

 of Innamincka. A small, probably stunted form, only 6-12 

 cm. high. [Seems to keep mostly to the sandy country, where 

 it was very plentiful.] H. striatum, Benth. Trinity Well. 

 H. floribundum, DC, and H. microglossum , Tate. Devils 

 Village, near Mount Lyndhurst. [The former is widely dis- 

 tributed and is mostly found in sandhill country.] H.

Kopperamanna. Also collected by R. Helms at Arkaringa 

 Creek, May 14, 1891, and placed in , the Tate Herbarium 

 Tinder Gnaphalium indutum, which it somewhat resembles 

 externally. A very distinct species, probably nearest to //. 

 moschatum, Benth., with the same woolly achenes, but the 

 plant is more compact and smaller than most forms of H. 

 moschatum, the leaves are narrower, the involucral bracts 

 much more woolly and not shining, the clusters are lateral 

 and in the forks as well as terminal, and are supported by a 

 few leaves at the base, while the flowers in each head are 

 reduced to one. [This plant was not observed further east, 

 but around Kopperamanna it was found in dense patches on 

 flooded ground, producing the effect of patches of cotton wool 

 at a distance.] 



Tlelichrysum semifertile, F. v. M. Cooper Creek, between 

 Innamincka and Kanowana. Flowers in each head about 20, 

 of which several, sometimes almost half, are sterile ; pappus 

 bristles 16 to over 20. Specimens from Innamincka (and 

 from west of Port Augusta) have erect stems, perhaps due to 

 the surrounding plants. This species forms a link between
