to the Gilbert River in about 17° 30' S. Lat. It rises in the 

 Ironbark ridges to the east of Gilberton, and flows N. and 

 W. through the pastoral and mineral country of the Car- 

 pentaria downs. It is fed by the Oopperfield, Stockman^ 

 Elizabeth, Lagoon, Lee, and other 'small creeks. Granite 

 and porphyry." (Whitworth, corrected by Mr. Spowers). 



I give these particulars in the hope that better specimens 

 may be further searched for in this locality. Twigs bear- 

 ing ripe pods are particularly desired. 



The interesting point about the specimens described is 

 that they prove to be the specimens figured by Mueller in 

 his Iconography as A. delibrata, and it throws light on 

 Mueller's view of that, (a very different) species in his later 

 years. Had Mueller stated the locality of the specimens 

 depicted in the Iconography, he would have saved users of 

 the work much trouble as regards some of the plates. 



The Einasleigh specimens consist of a few twigs in early 

 fruit, with a few flowers almost in the last stage. Unfor- 

 tunately Mueller's plate is, in some respects, unreliable. 

 The pods shown on the right hand twig are broader than 

 in the original, and are shaded to give the idea of maturity. 

 These pods, more than any other part of the plate, have 

 caused trouble. The original specimens are so immature 

 that one cannot be certain that the seeds will be oblique 

 at maturity, but the figure of the pods on the twig not only 

 leads one to assume that they are ripe, but figure 7 certainly 

 shows them so. There is no warrant for showing the 

 funicle and arillus as at 7. Ripe seeds are shown at figures 

 8 etc., but they are the result of pictorial license. The 

 flowering specimen at the left of the plate cannot be found. 



Fragments of flowers are persistent on the rhachis until 

 the young pods are as much as two inches long. This is 

 shown in the Einasleigh specimens and also in the Icono- 

 graphy plate.
