Merrittia Merrill gen. nov. in Philipp. Journ. of Sei., Bot. V (1910) p. 396. 



The new genus here proposed I refer with considerable confidence 

 to the tribe Inideae, placing it next to the Blumea in the Inuleae-Pluche- 

 inae as defined by Hoffmann in Engler et Prantl's Natürl. Pflanzenfam. 

 To me the plant has much the aspect of some species of Blumea, vvhile 

 in floral structure it approximates that of Blumea and allied genera. It 

 differs from Blumea and other genera in the Inuleae- Plucheinae especially 

 in its rather densely pilose receptacles, a character quite at variance 

 with the genera to which Merrittia seems otherwise to be allied.
