complete material, be looked upon as a connecting link 

 between A, triptycha and A. leptoneura. 



Var. tenuis var. nov. 



This is a form readily picked out from normal triptycha. 



The phyllodes are more slender and usually shorter, the 



young tips golden pubescent, the pistil densely tomentose. 



The Tammin specimens (J.H.M., Sept. 1909) may be taken 



as the type. 



Range (of the Variety). 

 In drier country. It has been obtained from the Wongan 

 Hills, 132 miles north of Perth, thence from Ounderdin to 

 Ooolgardie along the railway line, thence to Camps 56 and 

 61 of the Elder Expedition, say 200 miles north east of 

 Ooolgardie. Specific localities are Wongan Hills (Dr. A. 

 Morrison). Ounderdin (W. V. Fitzgerald as A. leptoneura). 

 Small shrub, Tammin (J.H.M.). Spreading shrub, 2-4 

 feet, Kellerberrin (W. V. Fitzgerald). Ooolgardie (L. 0. 

 Webster, 1900). 



Shrub of three feet, on sandhills, Oamps 56, 59, 61, Vic- 

 toria Desert. Elder Exploring Expedition 1891 (R. Helms). 

 Oamp 56, 19th September, is Lat. 29° 54' 35"; Oamp 59, 

 22nd September, specimen No. 9; Oamp 61, 25th September 

 (Queen Victoria Spring), is Lat. 30° 25' 38". I see no refer- 

 ence to this small prickly wattle in the journal, which is 

 not surprising. Mueller and Tate, in their account of the 

 botany of this Expedition (Journ. Roy. Soc. S*A., xvi, 351), 

 refer to this wattle as "A, triptycha F.v.M. (?)," showing 

 that they noted its difference from the normal species, but 

 I cannot make up my mind to give it specific rank.
