It is sometimes difficult to say how many nerves there 

 are in A. ixiophylla as the texture of the phyllodes may be 

 thickish and resinous, and it is difficult to distinguish 

 between the nerves and the striae. Mueller expresses the 

 idea in the use of the word "immerse" when speaking of 

 the veins of A. glutinosa. One sees long fissures but one 

 cannot exactly state their character with a lens. 



Gland. — Mr. Baker, in describing A. fuliginea speaks of 

 " gland wanting," but that is a slip. There is in all A. 

 ixiophylla material (whether attributed to A. fuliginea or 

 not), a rather large gland, but it is near the base of the 

 phyllode and not easy to see unless the phyllode is detached. 

 The liability to pass it over is enhanced by the ruggedness 

 of the surface of the phyllode owing to the glandular pro- 

 tuberances. 



Indument. — There is variation in the species. Bentham 

 expresses it as " glabrous or pubescent glutinous." This 

 is worthy of emphasis. The name fuliginea is owing to the 

 sootiness of the phyllodes, which can be observed in A. 

 ixiophylla from widely separated localities. 



Inflorescence. — (c) The inflorescence is referred to by 

 Bentham, . . . "solitary, or very shortly racemose." . . . 

 Most of the racemes 2-3 headed." In B. PI. ii, 387, 

 "Peduncles in pairs on short racemes of three or four." 



Mr. Baker says of A. fuliginea (d) "The inflorescence is 

 not in racemes," and again ..." Solitary or in pairs on 

 the end of the newly formed branchlets." 



Careful examination of a long series of A. ixiophylla (in- 

 cluding specimens labelled A. fuliginea by Mr. Baker) shows 

 that the flower-heads are in pairs on short racemes. In 

 one case (viz. Miles, Queensland, P. M. Bailey), the flower- 

 heads are solitary, in pairs or threes, on short racemes. It 

 will be seen that they all come under A. ixiophylla as 

 described by Bentham.
