The article places emphasis on two new Hohenbergia plant species from Brazil, Hohenbergia halutheriana (H. halutheriana) and H. viridorubra, in honor of the late bromeliad taxonomist Harry E. Luther. It mentions some of the differences of H. halutheriana from H. itamarajuensis to which it is closely related, including shorter flowers. A detailed description of the parts of H. viridorubra, such as leaves, flowers and filaments, is also provided.
