Near Darwin, C. J. F. Allen, Jan.-March, 1914. 



This species was first collected in 1912, and was in process of description as 

 a new species, when it was found that specimens collected in 1914 had been for- 

 warded to Kew, and described by Stapf and Jesson (Kew Bulletin, 1915, p. 93) 

 as a new species under Digitaria. There is nothing to add to the description 

 given. Large as is the genus Panicum (300 species) it is not larger than such 

 genera as Eucalyptus, Acacia, and Euphorbia, and the morphological dis- 

 tinctions upon which its subdivision into smaller genera is based are not larger 

 than those existing in the genera mentioned.
