#501 They called me Piper celtidiforme, also known as Piper fosbergii, Piper warburgii, and Piper usterii. I pay homage to the male botanists Fosberg (I couldn’t find his records), Uster (I couldn’t find his records), and E. F. Warburg, Edmund Frederic Warburg, or Otto Warburg. They first catalogued me in 1828.
