In regione austro-occidentali : in rupium fissuris montis " Ma- 

 troosberg " in ditione Worcester, alt. c. 5800 ped., Maio 1894; 

 Dr. R. Marloth, No. 1994. 



This is one of the plants which stands midway between Heli- 

 chrysum Vaill. and Helipterum DC, having less plumose pappus- 

 bristles than is generally the case in Helipterum, hardly more 

 plumose than those of Helichrysum sesamoides Thbg. ; yet its close 

 affinity to Helipterum eximium induces me to place it in this 

 genus. 



55. Athrixia asteroides Bolus & Schltr., sp. n. Suffi'utex 

 pluricaulis, gracilis, 40-60 cm. altus ; caulibus simplicibus vel 

 subsimplicibus, teretibus, scabro-puberulis, foliatis ; foliis erecto- 

 patentibus vel suberectis, sessilibus, linearibus acutis, basi sub- 

 cordatis, marginibus plus minusve revolutis, scabridis, internodia 

 duplo vel plus duplo excedentibus, 3-4 cm. longis, medio fere 

 0-2-0*4 cm. latis ; capitulis florum 2-3 cm. diametientibus, ad 

 terminalibus pluribus laxe subcorymbosis, longe pedunculatis, 

 distanter paucibracteatis, scabrido puberulis ; involucri foliolis 

 imbricatis, linearibus acutissimis. minute dorso puberulis ; fioribus 

 radii c. 20, iuvolucrum fere duplo excedentibus, e basi subfiliformi- 

 tubulosa in ligulam linearem acutam vel 3-dentatam, 0"8 cm. 

 longam, dilatatis, subtus sparsim puberulis; fioribus disci tubulosis,
