actual plant in Herb- Mus. Brit, proves tKat Plukenet's material 

 consists of a barren slioot of Mimosa ruhvicaulis and detached 

 fruits of an Acacia, What Rheede's plant is the writer cannot 

 definitely say. But the size of the capitula, as also some minor 

 points in the description, lead one to suspect that Mimosa ruhri- 

 caulis was used, at least in part, for both description and fig'ure. 



A new reference — Gronovius — is added by Linnaeus in his Sp. 

 PL, z,e., again he brings in an American plant. 



Briefly, then, it may be stated that (1) of the two Indian refer- 

 ences one is certainly to a mixture of an Acacia and a Mimosa^ and 

 the other, from w^hich Linnaeus derived his specific epithet, to a 

 figure for which the same Mimosa probably served at least in part, 

 and (2) an American plant is involved by Linnaeus, and in all 

 probability it was an American plant which Linnaeus had before 

 him when describing the species. 



"With these two main conclusions in view the writer feels com- 

 pelled to abolish the name M, InUia altogether, at least so far as 

 the Indian flora is concerned. 



The writer regards the material examined by him, all of which 

 has been referred to Acacia caesia and A. Iiitsia, as composed of 

 at least six species. In the enumeration and description of new 

 species which follows it will be noted that full synonymy is not 

 given, the reason being that the species have been so mixed up 

 that short of examining the actual specimens included under 

 either or both species by successive authors, it hos been found 

 impossible to decide w^hich particular plant is referred to.
