Phyllodia crasso-coriacea raro oblongo-lanceolata. Capitula laete lutea. 

 Calyx r" circiter longus glaber campanulato-cylindraceus ; dentes 

 breves triangulares conniventes. Petala lanceolato-linearia inferne 

 cohaerentia. Legumina coriacea fusca corapressa oblonga ad crassum 

 marginem flexuosa oligosperma circ. \^" longa, fere |" lata, in 

 stipitem brevem contracta, intus continua. Semina compresso-ovata 

 e sordide cano et nigro variegata. Strophiolum lividum cyrabiformi- 

 ianceolatum acuminatum in funiculum longissimum varie implexum 

 rufum transiens. 

 [In publishing this species as A. Muelleri, I stated my reasons foriiot 



adopting Dr. Miiller's manuscript name, which appeared to me too little 



appropriate in a genus which contains so many species with phyllodia 



twice or three times as large. — G. B.]

 tibus teretibus striatis, stipulis brevibus setaeeis v. subulatis deciduis, 

 phyllodiis parvis triangularibus crasso-coriaceis paucinerviis acutis

Phyllodia 1^-3'" longa et lata, '\\% A. decipientis non absimilia, nervo 

 infimo magis prominente. Flores I'" longi. Calyx satis laxus. Le-

lUustris Bentham forsan optime judicans hancce speciem cum sua A. 

 sublanata combinat, tacens autem de bracteolarum indole et ramo-
