As H. Harms has already pointed out (in Bot. Jahrb. xxm. 20-21 

 (1896) ) Pentapanax racemosum and P. subcordatum are better separated 

 from the other species of Pentapanax; they are terrestrial plants with the 

 inflorescence arranged in racemes.

Dr. Hayata seems to have based his description of the flowers on the 

 figures drawn by F. Hayami who mistook the black fungus on the half 

 rotten specimen for hairs. He also overlooked the existence of Pentapanax 

 verticillatum, P. yunnanense and P. Henryi in China and wrote of the genus 

 as new to the East Asiatic flora.
