 Subglabra, ramulis compresso-angulosis, phyllodiis coriaceis oblongis 

 subfalcatis brevissime petiolatis basi glanduligeris apice obtusis et 

 glanduloso-apiculatis tenuiter trinerviis subtilissime crebroque longi- 

 tudinaliter venosis, spicis axillaribus pedunculatis solitariis longius- 

 cule cylindraceis, sepalis subliberis oblongis laxis membraneis corolla 

 6-fida dimidio brevioribus, leguminibus 



Ad rivum Sturt's Creek, No. 97. 



Phyllodia l|-2|^" longa, 5-8'" lata (in unico suppetente specimine). 



Spices circiter sesquiunciales. Corollce vix 1'" longse. Species A. 



gonocladcB proxima. 



[The specimens are small and in flower only ; but they do not appear 

 to me to be in any point distinguishable from the A. aulacocarpa. — 

 G. B.] 



99. Acacia aulacocarpa. All. Cunn. 



^. brevifolia (F. Muell. MSS.), phyllodiis obUque ovatis 1-1|" longis. 

 Suttor Desert, No. 39. 



Legumen iw&cwai polUcare in stipitem semuncialem sensim contractum. 

 [Probably a distinct species : the pod is broader, narrowed into a 

 much longer stipes than in Cunningham's specimens, which, however, 

 are not ripe. The phyllodia are very much shorter. — G. B.]

Hand preetermittere volui speciem ut videtur raram A. acradenice pro-

[Very distinct in the unusually large size of the individual flowers. —
