 On forested slopes and ridges up to 1,600 m altitude. India to 

 southern China and Formosa through Malaya to tropical Aus- 

 tralia. 



The Old World form has long been referred to Ichnanthus 

 pollens (Sw.) Munro, the type of which was from tropical Amer- 

 ica. The Indian, Chinese, Philippine, Malayan, and Australian 

 material consistently differs from the American material in its 

 larger spikelets. A fragment of Bailey's type of Panicum 

 vicinum has kindly been supplied to me by Mr. T. C. White of 

 Brisbane, and it is identical with the Asiatic and Malayan form. 

 I had long suspected that our form was specifically distinct from 

 the American one, because as it occurs in the Old World it is a 

 native, not an introduced, grass. This suspicion has been verified 

 by Prof. A. S. Hitchcock, who went over the material with me, 

 first in Washington and more recently in Manila, and who like- 

 wise considers the Old World form to be specifically distinct 

 from the American one. 



In addition to the Philippine material and the Australian type 

 mentioned above the species is represented in the Bureau of 

 Science herbarium by specimens from the Malayan Peninsula, 

 southern China, Formosa, Sumatra, Java, New Guinea, and 

 Australia.
