Although the name was originally given by Klotzsch, the first official publication can be considered to be the one by Bentham. But Bentham’s description is very scanty, and Muller-Argoviensis’ description is the first one which is of any real value. This gives the main characters: “foliis subtus minute sparseque lepidotis” and “ovario dense rufo-tomentello.” However the ripe capsules were unknown and remained undescribed till today
