MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



[Vvl. 8, No, 5 



Helichrysum odoratissimum (L.) Less. Syn Gen, Comp. 301, 1832; Moeser, Bot. 

 Jahrb. 44: 242. 1910. 

 Gnaphalium odoratissimum L. Sp. PI. 855. 1753.

 high, leaves greyish, flowers bright golden-yellow, 1400 m., May 28, 1946, 16071. 

 Mlanje District: Mlanje Mountain; Luchenya Plateau, frequent in grassland edging 

 forest, herb 40-50 cm. high with numerous suberect branches forming a shapely

I am quite unable to see specific differences between H. 'odoratissimum and 

 H. hochstetteri. The individual capitula are slightly larger and more-flowered in 

 south tropical Africa and the Cape, and correspondingly smaller and fewer-flow- 

 ered in the northern part of the range, but there seems a gradual transition from 

 one to the other in the intermediate part.
