Acacia lutea cannot be conspecific with A. macracantha, 
which is described and figured (H. et B. Pl. Légum. 95, t. 28)

seen no specimens from Mexico. Acacia lutea Leavenworth 
being a synonym of Neptunia lutea Benth., the combination 
Acacia lutea (Mill.) Hitche. is valid under International Rules.
