#518 They called me Rhabdadenia biflora, also known as Echites billbergii, Dipladenia billbergii, Echites ehrenbergii, Rhabdadenia ehrenbergii, and Echites bilbergii. I pay homage to the male botanists Gustaf Johan Billberg, Christian Gottfried Ehrenberg, and Bilberg (I couldn’t find his records). They first catalogued me in 1860.
