In page Amorphophallus:

"

The oldest systematic record of the plants was in 1692, when Van Rheede tot Drakenstein published descriptions of two plants. The name "Amorphophallus" was first mentioned in 1834 by the Dutch botanist Blume[1] from Ancient Greek αμορφος amorphos "without form, misshapen" and φαλλος phallos "penis", referring to the shape of the prominent spadix.[citation needed] Between 1876 and 1911, Adolf Engler merged a number of other genera into Amorphophallus, with a final monograph published in 1911.[1]
